ผัดไทยPad thai

Rice noodles stir-fried with shrimp, dried-shrimp, shallot and egg in a tamarind–fish-sauce–palm-sugar sauce, served on a bed of fresh sprouts with lime, crushed peanuts and chili. The whole plate is a balancing act — sour, salty, sweet, hot, umami — and the wok work gives it the char you can't get any other way.

Technique notes

This is a stir-fry at full speed, and its hard part is the wok-heat part: the wok must be hot enough that the noodles sear instead of steam and the sauce clings instead of pools, but everything is added in a few minutes flat, so the mise en place is the recipe — every element pre-measured and on the bench before the wok is lit. The sauce is the balancing half of the dish: tamarind for the sour, fish sauce for the salt-and-umami, palm sugar for the sweet, dried shrimp for the depth — and you finish it at the table, not in the pan (see the last step). The rice noodles need to be soaked, not boiled, so they finish in the wok; and the cutting — julienne of the sprout stems, clean shrimp shells off — is what decides whether the texture reads as "pad thai" or as a stir-fry with noodles in it.

Equipment

Wok or 28 cm (11 in) heavy skillet
Wide, flat-bottomed bowl for soaking the noodles
Mortar and pestle (or a small dry pan) for the dried shrimp
Deep serving bowls — the sprouts sit under the noodles

Ingredients

200 g (7 oz) medium-diameter (5–6 mm) rice noodles, from a fresh block or a good dried one
200 g (7 oz) peeled medium shrimp, or 150 g (5 oz) chicken thigh cut in 1 cm strips if you can't get shrimp
40 g (3) dried shrimp (kai khae) — small, the brown kind, not the big pink shrimp of the packet
40 g (3) shallots (or a 1 (100 g) spring onion), minced fine
5 g (1 clove) garlic, grated
5 g (½ tsp) ground dried chili (or 2 (10 g) bird's eye chilies, minced) — for the heat of the sauce itself
2 (from 120 ml) eggs
30 g (2 tbsp) tamarind concentrate (or 20 g of good tamarind paste, strained) — the sour
20 ml (1⅓ tbsp) fish sauce — the salt and umami
12 g (1 tbsp) palm sugar (or dark brown), grated to a fine powder — the sweet
15 ml (1 tbsp) peanut or vegetable oil, plus 15 ml of the oil from the fried dried shrimp
200 g (7 oz) fresh mung-bean sprouts (the thick white kind, not the thin Asian-market "baby" ones)
50 g (2 stems) long beans, 4 cm lengths (or more bean sprouts)
25 g (1 bunch) chives (or scallion), cut in 4 cm lengths
2 (90 ml) limes, cut into wedges — for the table
3 (20 g) bird's eye chilies, cut on the diagonal — for the table
25 g (⅓ cup, loose) roasted peanuts, crushed to a rough crumb — for the table

Method

Soak the noodles. Put them in the warmest tap water you'll comfortably take and weigh them down with a plate so they're under the surface. 20–25 min until pliable but with a chalky center — they must still bite, because the wok finishes them. If they're fully soft now, they'll be mush then. (Dry, packet noodles? Soak them in near-boiling water and cut to 15 cm lengths first, so they all go into the wok at the same time.)
Make the dried-shrimp paste and the sauce. In a dry, unheated pan or mortar, pound the dried shrimp to a rough, gritty meal — not a powder, you want bits in the wok. Into a small bowl, combine the tamarind, the fish sauce, the palm sugar, the garlic, the ground chili (or the minced bird's eye), and 50 ml (2 fl oz) of cold water; stir until the sugar and tamarind are dissolved. Taste it: it should be aggressive — much stronger than the finished dish will be, because it thins over the noodles. That's the balance you're building before the wok is lit.
Everything else on the bench. Peel the shrimp, mince the shallots, cut the beans, trim the sprouts to 8 cm lengths, separate the yolks, and crack each one into its own small cup. Have the peanut oil measuring spoon ready, the crushed peanuts, the chilies on the diagonal, and the lime wedges at the table. Every one of these is a 10–20 second job in the wok, and you won't have any more than that between one and the next.
Light the wok and dry-fry the shrimp. On a high flame, get the wok properly hot — 2 min, a thin wisp of smoke is the cue. Pour in the 15 ml oil, shake it around, add the dried-shrimp meal, and dry-fry it 30–60 s until it's deep brown, crisp, and the oil in the wok has turned a rich amber and smells of nut and sea. This is the "wok smell" step from the heat article — the flavor of the dish starts here, not with the noodles. Leave this oil in the wok; you're adding everything to it.
The shrimp (or chicken). Toss the peeled shrimp into the oiled wok and stir-fry 30–45 s, just until the edges turn from grey-white to pink and the flesh firms — the center should still be a touch raw, because it'll sit on top of the noodles and finish. Tip them into a bowl and set aside. The oil left in the wok is now carrying their flavor, and that's exactly what you want for the next stage.
The shallots. The same oil, same wok, same heat. Add the shallot and fry 45–60 s, stirring, until the edges just begin to brown and the raw onion smell has turned sweet. This is the "aromatics in hot fat" move from the stir-fry article — you're not making a base, you're just giving the fat a head start before the noodles meet it.
The noodles and the egg. Add the drained noodles in a single loose handful, and the instant they're in the wok, add the two raw eggs in a thin stream along the surface of the noodles — not into one pile. The eggs break up as the noodles come together, and the film they set on the noodle surface is what lets the wok char them instead of letting them steam. Stir-fry, tossing and turning with tongs or a spatula, 1–2 min, until the noodles are glossy, the edges are just beginning to darken, and no pale, chalky centers are left. The noodle article covers exactly this point of doneness; look for "a char on the edge, a bite in the center."
The sauce and the rest. Push the noodles to one side of the wok, pour the sauce down the middle, and 15–20 s of it will spit and steam — that's the point, the steam is what loosens any dry edges. Toss the noodles in, and in the same motion tip in the shrimp, the long beans and the chives. 30 s at most: the beans are there to soften, not to cook through, and the chives are a color, not a vegetable. Taste one noodle against the sauce — it should read sour first, salty second, sweet to carry it. If it's flat, a few drops of the fish sauce before the table is the fix; if it's bitter, a small extra measure of the palm sugar.
Plate it — and finish it at the table. Tip the noodles out of the wok. Into each deep bowl, put a generous bed of the fresh, uncooked bean sprouts and a few chives on top of them; on top of that, the noodles. Scatter the crushed peanuts, the cut chilies, and a lime wedge on the side. Squeeze the lime over the noodles before eating, not in — the acid loosens the sauce and cuts the richness, and that's the balance you can't get if you add it before the noodles are cooked. The peanuts are the crunch, and the chilies are there because most people under-estimate the heat of the table.

Common failures

Mushy, gummy noodles. Soaked too long (step 1 said 20–25 min, not 40), or the wok was too cold in step 7 so they steamed instead of searing, or both. The fix for a wok that won't get hot: a heavy skillet on a high ring, or split the batch into two and cook each one properly.
Flat, "pad thai from a kit" flavor. The sauce in step 2 wasn't tasted before it went in, or the dried shrimp didn't get the dry-fry in step 4. The dried shrimp is where the "Thai" comes from in the background flavor; the sauce balance (sour-first, then salty) is where the dish comes from at the front of the mouth.
Raw, grey shrimp. Over-cooked in step 5, or tipped out onto a cold plate where they stalled and went rubbery. The shrimp should be just barely cooked when it leaves the wok, because it finishes on the noodles; a 10-second overcook is the whole reason the shrimp in pad thai is sometimes a chewy disappointment.
Everything is cold and limp at the table. The plate came out of the wok slow. The bowls should be at the side of the wok, ready; the sprouts, peanuts, and chilies are already measured out in step 3. The whole plate is a 90-second assembly — that's the speed it's meant to happen at.

Variations & substitutions

Chicken. Swap the shrimp for 150 g of chicken thigh (step 5): cook it until just past white, and keep the dried shrimp in the wok — the dried shrimp and the fresh protein are different jobs, and dropping the dried shrimp with the fresh one is how home versions lose the depth.
No tamarind concentrate. 20 g of tamarind paste (the thick, dark block), soaked in 40 ml of hot water and strained through a fine sieve, is the same move with more time; a good bottle of tamarind concentrate (the kind from the Thai aisle, not the "tamarind-flavored" syrup of the baking aisle) is the same move with less.
Milder. The heat in this recipe is split two ways: the ground chili in the sauce (step 2), and the raw chilies at the table (step 9). Drop the first to 2 g, and leave the chilies at the table for the ones who want the heat — the table-side chili is the polite part of the dish.

What to serve with it

This is a whole meal on its own — the noodles, the shrimp, the egg, the sprouts, the peanuts are the plate. A som tum (green papaya salad) is the classic counterpart: same table, same acid, completely different body, and the two of them together cover the whole sour–salt–sweet–hot range. If you want a second element that doesn't compete, a green curry with jasmine rice finishes the meal on the rich, coconut side and lets the pad thai do the light, charred work. An iced Thai tea (or a cold lager) is the drink that goes with it, by long tradition, and there's no reason to argue with that.
