How to make a crudité platter weighed per guest, blanched by the clock, arranged by colour

Crudités are, in Merriam-Webster’s words, “pieces of raw vegetables (such as celery or carrot sticks) served as an hors d’oeuvre often with a dip.” For the food the word is plural, in English and French. Say kroo-dih-TAY in the US, stress at the end (Merriam-Webster: \ˌkrü-di-ˈtā\); British speakers stress the first syllable, /ˈkruː.dɪ.teɪ/ (Cambridge Dictionary); French is [kʁy.di.te], with the French ü.

A correction to the pages that rank: cru means raw; crudité means rawness, “état ou qualité de ce qui est cru” (TLFi). And the French plate need not be raw: Larousse’s crudités are “légumes crus ou cuits (betterave, poireau) servis froids et assaisonnés de vinaigrette”, raw or cooked vegetables served cold in vinaigrette, eaten with a fork. The American tray of sticks and dip is French in name, American in format.

Is it a veggie tray? In substance, yes, as My Quiet Kitchen says. The veggie tray grew from the relish tray (its story is on the Thanksgiving board) and the supermarket tub of ranch; a crudité platter is cut to size, arranged by colour and carries two or three dips.

Our picks, inside the published figures below: 5 oz (140 g) of trimmed vegetables a guest when the platter is the main nibble before a meal, 3 oz (85 g) when it is one of several appetizers, 6 oz (170 g) for a long party with no meal; 3 tbsp of dip a guest. Buy about a third more by weight.

Cups mislead: a cup of snap peas weighs 2.2 oz (63 g), a cup of cherry tomatoes 5.3 oz (149 g); six common crudités average 3.7 oz (104 g) a cup (USDA), close to ATK’s per-guest floor of 4 oz (115 g). Store trays count smaller: a Taylor Farms serving is 1 cup (240 ml) of vegetables plus 3 tbsp of ranch, 123 g in all, about 2.7 oz (78 g) of vegetables, so its “About 12 servings” feed about eight guests at ATK’s floor.

Purchase weight is what the ranking pages leave out. The USDA Food Buying Guide gets 0.70 lb (318 g) of sticks from 1 lb (454 g) of carrots; asparagus loses 47% at the butt end (USDA SR28), so buy twice what you serve. For broccoli and cauliflower florets the USDA datasets disagree, keeping anywhere from 39% to 89% of a cauliflower, because each starts from a different head; we use about 60%. Alberta’s 1983 quantity guide allowed even more: serve 120 to 160 g, buy 170 to 250 g, about half as much again, “because of large amount of waste”.

Platter sizes are ours, scaled from Skinnytaste’s 15.5 in (39 cm) round for six. Past about 16 guests, split into two platters and keep a third in the fridge: USDA FSIS advises replacing small platters “often, rather than adding fresh food to a serving dish already on the table.” For the rest of the food, use the party food calculator or the catering calculator.

The freezer times are the National Center for Home Food Preservation’s, for a different job: before months in a freezer, blanching must stop the enzymes that dull flavour and colour. A platter is eaten the same day and needs only colour and a softer bite: about a quarter of the time or less for broccoli and beans, half for cauliflower. Better Homes & Gardens’ “3 minutes” for broccoli is the freezer figure.

Bring a big pot to a rolling boil, salt it, and set a bowl of ice water beside it. Blanch one vegetable at a time in small batches, so the water comes straight back to the boil, and time from there. Lift them into the ice until cold right through, drain, spin in a salad spinner and spread on towels: wet vegetables thin the dip.

Salt is for flavour. ATK uses “½ cup of table salt per 2 quarts of water”, ½ cup (145 g) in 2 quarts (1.9 L), about 7% by weight; Daniel Gritzer’s tests at Serious Eats found salt changed flavour, not colour or crunch. Our pick is about 3%, close to sea water: 3 tbsp of table salt to 2 quarts (1.9 L). The ice matters more: in Gritzer’s blind tastings, ice-cooled vegetables were “consistently crisper, greener, and fresher-tasting” (Laila Ibrahim’s summary, Serious Eats, 2026).

Why green goes bright, then olive: in the first seconds, gas trapped between the cells is driven out and stops scattering light (J. Kenji López-Alt, Serious Eats). Then heat and acid swap the magnesium in chlorophyll for hydrogen, making olive pheophytin, faster the more acidic the liquid ¹; boiling makes more of it than steaming ². So: short time, ice at once, and no lemony dip on blanched greens until they are eaten.

Mix long and short cuts of one vegetable, as ATK suggests, and spears, coins and florets give rhythm even in one colour. A julienne, ⅛ in (3 mm) thick, is too thin to dip: keep it, a chiffonade of mint and a cucumber brunoise for the dips, and a tourné radish for showing off. The knife-cuts chart draws each cut at full size; knife skills covers the grip.

Water or towel? Carrots, celery, jicama and radishes stay crisp submerged: water moves into their cells and pushes them taut, which is also how limp celery revives. Broccoli and cauliflower waterlog, so they get a damp towel. Peppers and cucumbers go in dry and airtight.

The white blush on carrot sticks is not spoilage. It starts as surface drying that scatters light, grows faster in drier air and partly reverses in water ³; after a few days lignin forms on the cut cells and the white stays ⁴. McGill’s Office for Science and Society: neither has “anything to do with the safety”.

Two hours at room temperature, one hour above 90°F (32°C): the FDA and USDA FSIS rule, set out in full on the flagship. Under the FDA Food Code (2026 edition, unchanged from 2022 on this point), heat-treated plant food needs time and temperature control, so every blanched vegetable does, along with cut tomatoes, cut leafy greens (torn radicchio counts), raw sprouts (garnish with herbs instead) and every dip here: dairy, egg, bean, anchovy, roasted-pepper and garlic-in-oil dips all count. Raw carrot, celery, pepper and cucumber sticks are not on the Food Code’s list, but USDA still says to refrigerate cut vegetables within 2 hours, so clock the whole platter. Blanching broccoli makes it more regulated, not less.

Wash hands for 20 seconds and cut on a board that has not had raw meat on it (FDA). Wash the vegetables under running water before peeling, scrub cucumbers with a clean brush, skip soap and produce washes (FDA), and dry well. Hold it cold: FSIS suggests “nesting dishes in bowls of ice”, so set the dip bowls in crushed ice (it extends the clock only while the dip stays at 40°F (4°C) or colder), chill the platter, and swap in a fresh one from the fridge rather than topping up. Packaged trays are not exempt: in 2018, pre-packaged vegetable trays of broccoli, cauliflower, carrots and dill dip were linked to a cyclosporiasis outbreak: 250 laboratory-confirmed cases in people from four Midwest states, eight of them hospitalized (CDC; the trays were bought in three, since Michigan’s cases bought theirs in Wisconsin).

Four pigment families paint the platter. Chlorophyll (broccoli, beans, cucumber, snap peas) goes olive with acid and time. Carotenoids (carrots, peppers, tomatoes, orange cauliflower) are fat-soluble ⁵, so they stay put in water and beside wet dips. Anthocyanins (purple carrots and cauliflower, radicchio, radish skins) dissolve in water and change with pH: red in acid, blue and unstable above about pH 6 ⁵, ⁶. Hard, alkaline tap water can tint purple cauliflower blue-green, and a purple stick left standing in a white dip stains it. Betalains (beets) hold colour from about pH 3 to 7 but bleed into anything wet ⁷: keep red beets away from white dips, or use golden and Chioggia.

Read it as a colour wheel with no neighbours the same: our colour on the plate guide explains why, and the plate colour pairing tool picks a platter to set it off.

Three 40 oz (1.13 kg) Walmart trays cost $35.91 and, if about 63% vegetables by weight like a Taylor Farms serving (78 of 123 g), give 16 guests about 4¾ oz (135 g) each. Homemade is about $12.50 of vegetables at 2023 prices, plus dips, with nine vegetables cut, blanched and coloured your way; the dips and three years of price rises narrow the gap, so make it for variety and freshness more than the saving.

For about five hundred years, crudités also meant indigestion. The first French sense, in 1398, is the state of being hard to digest (TLFi); the Académie française kept the stomach sense, “Il a des crudités d’estomac”, from its 1762 edition to its 1932 one. Doctors forbade raw food: the Montpellier consultation Tobias Smollett printed in 1766 bans “autres crudites, alimens grossiers, ou de difficille digestion”. Escoffier’s Guide culinaire (1907) never uses the word.

Vitamins turned it round. In 1919 Gustave Houlbert told nursing and pregnant women to eat “des crudités tels que des hors-d’œuvres”; in 1931 the naturist doctor Paul Carton prescribed “Les hors d’œuvre vitalisants”. “Assiette de crudités” is in print by 1955 (“plat de crudités” by the 1930s).

English had the word before its dictionaries: Etymonline says 1960, but James Beard and Sam Aaron wrote in 1954 of “serving a variety of raw vegetables (the French call this les crudités) with two or three good dips or dunks”. California Dip (1954 to 1955) was first served with potato chips and crackers; ranch was devised in Alaska around 1950, and “Veggie Tray (with Ranch Dip)” was in a Wisconsin student dining ad by 1990.

Shaped trays are older than Pinterest. Southern Living served dip “from a wreath of fresh vegetables” in 1979, and on 21 December 1983 the Twin Falls Times-News pinned vegetables to a styrofoam cone: “The easy-to-create vegetable Christmas tree is an alternative to the relish tray.” The relish tray’s story is on the Thanksgiving board.
