Shrimp Cocktail Recipe: Tender Shrimp at 145°F (63°C)

Is shrimp cocktail raw or cooked? Cooked, to 145°F (63°C)

Shrimp cocktail is cooked shrimp, chilled and served cold. It is not ceviche, where raw seafood is “cooked” by lime juice (our shrimp ceviche explains that dish and its risks); every shrimp in a cocktail has been heated until opaque. What no ranking recipe gives you is the number. The FDA says “Most seafood should be cooked to an internal temperature of 145°F” (63°C). For shrimp in particular, both the FDA and FoodSafety.gov give a visual test instead, flesh that is “pearly” and “opaque”, and FoodSafety.gov’s chart prints no number for shrimp at all. The FDA Food Code, the model rulebook for US restaurant kitchens rather than home advice, is more specific: fish must reach 145°F (63°C) for 15 seconds, and its definition of fish includes crustaceans such as shrimp.

Cooks who chase tenderness quote a lower figure. J. Kenji López-Alt’s sous-vide tests at Serious Eats found shrimp “soft and mushy” below 125°F (52°C) and “tough and rubbery” above 140°F (60°C), with 135°F (57°C) “barely opaque” and juicy. That window is real, but it is for shrimp held at one temperature right through, and the low end of it is not opaque. For a party platter that will sit out, feed guests you do not know, and include pregnant or older guests, we cook to opaque all the way through, which is the FDA’s 145°F (63°C).

The reason that costs so little texture is the method. Kenji’s own line on boiling is blunt: “At a boiling-hot 212°F (100°C), the outsides of your shrimp are going to get tough no matter what.” A jumbo shrimp dropped into a rolling boil has a centre at 145°F (63°C) and an outer layer far hotter. Started in cold water and never heated past 170°F (77°C), the outer layer cannot overshoot by much, so a shrimp that is safely opaque in the middle is still tender at the edge. The cut test in step 5 and a thermometer in the thick end are how you know.

Four ways to cook shrimp cocktail, and why we start cold

Recipes for shrimp cocktail split into four camps, and the difference between them is how hot the water is when the shrimp are in it. The rolling boil is the oldest: Chef John’s Allrecipes version boils jumbo shrimp in a court bouillon for “about 5 minutes”. It is the fastest and the easiest to overdo, for the reason Kenji gives above: 212°F (100°C) water toughens the outside before a big shrimp’s centre is done.

The second camp drops the shrimp into boiling water and lets the temperature fall. Once Upon a Chef keeps the pot on the burner and cooks 16/20s for “exactly 3 1/2 minutes” in salted, sugared water, noting that “The water will not really return to a boil once you add the shrimp; that’s okay”; The Kitchn takes the pot off the heat and pulls them after 1 1/2 to 2 minutes. The falling temperature limits the overshoot, and it is a good method if you trust the timer and your shrimp size. Its weakness is that the time depends on how much water, how many shrimp and how cold they were.

The third camp, which this page uses, starts cold. America’s Test Kitchen’s 2012 recipe heats shrimp from cold water to 170°F (77°C), then finishes them covered off the heat. Serious Eats goes gentler still: Daniel Gritzer starts shrimp in a court bouillon cooled down with an equal amount of cold water and stops at 150°F (66°C), writing that “By starting cold and not exceeding 150°F [66°C], instead of dropping them into boiling liquid, you get the plumpest, most tender shrimp from edge to edge.” We stop the water at 170°F (77°C) rather than 150°F (66°C) because the shrimp must reach 145°F (63°C) in the centre, and with water at 150°F (66°C) that last stretch is slow to judge.

The fourth idea is a brine, and it is an add-on to any method rather than a method. Serious Eats dry-brines shrimp with salt and baking soda (1 teaspoon kosher salt and 1/4 teaspoon baking soda per pound, 450 g, in its brining guide) for 15 minutes to an hour in the fridge, which keeps them plump and juicy; Gritzer describes the texture as a “tightly-filled water balloon”. Once Upon a Chef’s salt and sugar in the boiling water is different: three and a half minutes is seasoning, not a brine. If you want the snappier texture, toss the 2 pounds (900 g) of deveined shrimp with 2 teaspoons of kosher salt and 1/2 teaspoon of baking soda an hour before step 4, refrigerate, and halve the poaching salt to 2 tablespoons (about 18 g) Diamond Crystal.

How many shrimp per person, and a 20-guest scale line

Shrimp are sold by count: 16/20 means 16 to 20 shrimp per pound (35 to 44 per kg), so each raw shell-on 16/20 weighs about 23 to 28 g. This recipe’s 2 pounds (900 g) is about 36 shrimp, 4 to 5 per guest for 8, which matches The Kitchn’s “3 to 5 shrimp per person” for a starter. Peeling and cooking shrink them: by the USDA Food Buying Guide’s yield figure, 1 pound (450 g) of shell-on shrimp gives about 0.54 pound (245 g) of cooked, peeled meat, so 2 pounds (900 g) shell-on is about 490 g (just over 1 pound) on the platter, roughly 14 g per shrimp.

Count labels drift too. A foodservice rule of thumb is one size lost to peeling and another to cooking, so a bag of cooked, peeled 26/30 cocktail shrimp is about the same shrimp as a raw shell-on 16/20. Buy by the raw count if you are cooking, and do not compare a cooked bag’s count with a raw one’s.

Our guide, by role on the menu, for 16/20 shrimp: 4 to 5 each when shrimp cocktail is one starter among several; 6 to 8 each when it is the only starter; 12 to 14 each as a main course. For 20 guests at a drinks party with other food, 4 each is 80 shrimp, about 4 1/2 pounds (2 kg) of raw shell-on 16/20; if shrimp is the star, 6 to 8 each is 120 to 160 shrimp, 7 to 9 pounds (3.2 to 4.1 kg). Cook in 2-pound (900 g) batches with fresh water and ice each time rather than crowding one pot. Two batches of sauce (about 2 2/3 cups, 640 ml) give 20 guests 2 tablespoons each. Our catering calculator does the same arithmetic for the rest of the menu.

Buying shrimp: frozen beats fresh, and read the label

By 2023, according to a NOAA Fisheries report, “93% of shrimp consumed in the U.S. were imported”, most of it farmed. Almost all of it travels frozen. Cook’s Illustrated found that “virtually all shrimp sold at fish counters were bought previously frozen and thawed by the fishmonger”, and that within a day of thawing the texture starts to soften. So the bag in the freezer case, individually quick-frozen (IQF) and thawed by you the night before, is usually fresher than the “fresh” shrimp on ice.

Turn the bag over. The ingredient list should say shrimp, perhaps with water for the protective ice glaze. Sodium tripolyphosphate (STPP) and similar “moisture retention agents” are soaked in to hold water; the National Fisheries Institute’s labelling guidance says they must be declared, and they add sodium. For shrimp cocktail they matter more than in a curry: the shrimp is eaten plain and cold, and a soaked shrimp poaches up bouncy, slightly translucent and salty, with any added salt in the poach doubling up. Black spots on shells are an enzyme reaction, not spoilage, according to the American Shrimp Processors Association, though they show on a cold platter.

Size: 16/20 jumbo is the standard in the recipes we read (America’s Test Kitchen, Once Upon a Chef, The Kitchn) and the easiest to cook evenly; 21/25 gives more shrimp per pound for a crowd and cooks a minute or two faster. Shell-on, deveined “EZ-peel” shrimp are the best compromise: the shell is already slit and the vein gone, but the shell is still there for cooking.

Cocktail sauce: the 4 to 1 ratio, and why the horseradish fades

What is in shrimp cocktail sauce? Ketchup and prepared horseradish, sharpened with lemon, Worcestershire and hot sauce. The recipes we read range from 3 parts ketchup to 1 of horseradish (Chef John, with chili sauce in the mix) to 24 to 1 (The Kitchn, which gets its heat from hot sauce, chili paste and pepper instead). America’s Test Kitchen’s 4 to 1 sits in the middle, and it is ours: 1 cup (240 ml) ketchup to 1/4 cup (60 ml) horseradish, starting at 3 tablespoons and tasting. US bottled chili sauce can replace a quarter of the ketchup for texture; it is a tomato condiment with vinegar and onion, not a hot sauce, and Heinz’s carries more sodium per tablespoon than ketchup.

The heat in horseradish is a volatile compound, allyl isothiocyanate, made when grating breaks the root’s cells, and vinegar stops the reaction at whatever level it has reached. From then on it only goes one way. A 2021 review in Horticulturae notes that ground horseradish “will slowly lose its pungency, become darkened, and develop off flavors even under proper refrigeration”, and Oregon State University Extension says homemade horseradish relish loses its pungency within 1 to 2 months in the fridge. The Kitchn says a made-ahead sauce tastes hotter; any extra heat would have to come from its chili paste, hot sauce and black pepper, not the horseradish. Our advice: make the sauce up to a week ahead, and stir in the horseradish, or a spoonful more, on the day. An old jar is weaker than a new one, so taste.

Cocktail sauce without horseradish works, but it is a different heat. Use hot sauce or a pinch of cayenne with extra lemon: chili heat lingers in the mouth, while horseradish hits the nose and fades. Two cousins use a different sauce entirely. A British prawn cocktail is dressed in Marie Rose sauce, mayonnaise with tomato ketchup, Worcestershire and lemon, usually over small prawns and shredded lettuce in a glass. A Mexican cóctel de camarones sets cooked shrimp in a loose, spoonable tomato and lime broth with onion, cilantro (coriander) and avocado, more like a cold soup than a dip.

History: a New York club’s oyster cocktail, 1891

The parent of shrimp cocktail is the oyster cocktail, and the earliest account we found is a New York Herald report reprinted in the Red Lake Falls News of Minnesota on 26 March 1891. It credits “the young barkeeper of the Manhattan club”, at Fifth Avenue and Thirty-fourth Street, and says that “alcoholic liquors do not enter into its composition”: lemon juice, Tabasco, pepper sauce, a trace of vinegar, salt and pepper, poured over half a dozen Blue Point oysters in a goblet. The paper explains the name: “The idea of the newly devised drink is to combine the preliminary cocktail and the first course of a dinner.” The cocktail was the slot in the meal, not the liquor. No ranking recipe page we read mentions this credit.

Tomato and horseradish arrived quickly. In March 1892 a London item reprinted in New York’s Medical Record had the Manhattan Club’s version “fill[ed] up with tomato juice” and laced with horseradish, and the San Francisco Argonaut reported that “tabasco, chilli, lemon-juice, and horse-radish” left an oyster cocktail “heated to a fiery temperature”. In 1904 the stage star May Irwin printed an “Oyster Cocktail Sauce” in May Irwin’s Home Cooking: lemon juice, grated horseradish, onion, Worcestershire, Tabasco and a quarter cup of ketchup, the ingredients of today’s sauce, though heavier on lemon, and bottled “oyster cocktail sauce” was on grocery shelves by 1905. Fannie Farmer’s revised Boston Cooking-School Cook Book (1906) said to “serve in cocktail glasses”. Shrimp came last, as an afterthought: Lowney’s Cook Book (Boston, 1907) gives a clam cocktail, then one line, “Shrimp Cocktail. Substitute one pint shrimp for clams, and proceed as for clam cocktail.” By 1910 to 1916 it was on hotel menus from Arkansas to Atlanta and Victoria, British Columbia, usually priced at or below the lobster cocktail.

Three popular origin stories do not survive the record. The Gold Rush miner who dropped oysters into his whisky glass turns up earliest, in the record we found, in a 1928 trade paper, The Restaurateur, which dates the event “about 1866”, well after the Gold Rush and some sixty years before the article, with no name or saloon. The idea that Prohibition left cocktail glasses idle and restaurants filled them with shrimp is undone by Steuben and the United States Glass Co., which were selling oyster cocktail glasses in 1907 to 1910, a decade before Prohibition. And Al Levy of Los Angeles, called “Inventor of the Oyster Cocktail” in his 1941 New York Times obituary, is described in an 1897 Los Angeles Times profile as a former waiter who had started out a few years earlier selling oyster cocktails from a pushcart, an existing street trade, and who then copied a San Francisco fad for bottled oyster cocktails. The profile never calls him the inventor; even his obituary’s text says only that he “popularized” it.

The later landmarks are firmer. The Golden Gate in downtown Las Vegas began selling a 50-cent shrimp cocktail in 1959 and raised it to 99 cents only in 1991. “Prawn cocktail” is on a Hong Kong hotel menu by 1934 and in British cookbooks by 1939, and boomed from the 1960s; “Marie-Rose” was a classical French name for a shrimp garnish before it was a pink sauce, and the Mary Rose Trust has dismissed the story that its wreck divers invented it: “Not one of them has any recollection of this happening.”
