Prawn & noodle salad with crispy shallots
About this recipe
Vietnamese cooking layers fresh herbs (mint, basil, cilantro) into nearly every dish, served alongside grilled meats, broths (pho being the most famous), and the salty-sour-sweet-spicy balance of nuoc cham. Heat is on the table, not built into every dish.
As a seafood dish, Prawn & noodle salad with crispy shallots demands timing precision: the difference between perfect and overcooked is often less than 90 seconds, and the result of overshooting is a textural penalty there's no fixing.
The scaler above rewrites every measurement to your target serving count, with proper culinary fractions (½, ⅓, ¼) instead of decimals so the recipe stays measurable. Cook Mode steps you through it hands-free.

Method
- step 1
- For the crispy shallots, heat 5cm of oil until hot in a wok. You will know the oil is hot enough when one piece of shallot sizzles as soon as it’s dropped in. Toss the shallot slices with flour, shake off excess and fry in the oil until golden. They fry quickly, about 1 min. Drain on kitchen paper, sprinkle with salt and set aside.
- step 2
- To make the dressing, mix the lime juice, sugar, fish sauce and garlic and set aside. In a large mixing bowl, pour boiling water over the noodles. Leave them for 2 mins or until they are just cooked, then rinse under cold water. Drain well, shaking the sieve numerous times to get out the excess water, then place back in the bowl. Add prawns, onion, chilli, cucumber and herbs. Pour the dressing over, mix, then sprinkle with the shallots and peanuts.
Cooking notes
Scaling works best when you weigh ingredients rather than measure by volume — small differences in packing can compound at higher multipliers.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Prawn & noodle salad with crispy shallots
Prawn & noodle salad with crispy shallots is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Seafood is the most scaling-sensitive protein because the overcooking window is narrow and the penalty is steep. Scale Prawn & noodle salad with crispy shallots per piece if you can — cook three fillets in two batches rather than crowd the pan into one. Sauce-based seafood dishes scale linearly, but always taste before adding more salt: brininess from the seafood itself doesn't scale predictably.
Because this recipe is built around flour and sugar, weighing in grams (rather than measuring cups) is what separates a consistent bake from a one-time win. A cup of all-purpose flour can weigh 113 g or 150 g depending on how you scoop — that's a 30 % swing that ruins texture.

Beyond the recipe
Substitutions & make-ahead — Prawn & noodle salad with crispy shallots
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Prawn & noodle salad with crispy shallots is doing structurally — here's the practical version.
Substitution ideas
Brown sugar
Brown sugar = white sugar + molasses. For 1 cup light brown sugar, use 1 cup granulated sugar + 1 tbsp molasses; for dark brown, 2 tbsp molasses. Coconut sugar is a near-1:1 swap with slightly less caramel depth — works for both light and dark.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Seafood is the worst-tempered category for make-ahead — texture and flavour both degrade quickly after cooking. Prawn & noodle salad with crispy shallots should ideally be cooked the day it's served. If a make-ahead is unavoidable, prep components (the sauce, marinade, vegetables, garnishes) the day before and cook the fish or shellfish at the last moment. Cooked seafood develops a pronounced fishy off-flavour within 24 hours even when properly refrigerated.
