Quick Caramel Lemongrass Prawns with Mango-Herb Rice Noodles and Chili-Lime Dust
Modern Vietnamese week-night cooking—fast wok heat, fresh herbs, and the sweet-salt punch of nước mắm. Lime-sharp acid lands first, fast-tracked by palm sugar sweetness. Fish-sauce salinity rolls in next, chased by gentle chili heat. Toasty sesame hides at the back, smoothing the ride with quiet umami.
Ingredient List (Serve 4 GF)
• Raw tiger prawns, peeled, 24 (about 600 g)

Step-by-Step Instructions
Step 1 – Mise En Place (5 min)
Set out a carbon-steel wok, pot for noodles, spider strainer, and mortar. These tools move hot and fast—vital for a 30-minute run.
Step 2 – Chili-Lime Dust (3 min)
Pound sesame, salt, lime zest, and chili flakes in mortar until coarse. Keep dry.
Step 3 – Hydrate Noodles (6 min)
Boil 1 L water, drop rice vermicelli for 2 min, drain, rinse cold, hold.
Step 4 – Caramel Build (4 min)
In wok on medium, melt palm sugar with 15 ml water to a bronze syrup. Stir once the edges darken to avoid crystals.
Step 5 – Flash Aromatics (1 min)
Add oil, lemongrass, garlic, chili. Sizzle 30 sec—watch for golden edges, not brown.
Step 6 – Prawn Sear (4 min)
Raise heat. Toss prawns in a single layer. Flip when they blush pink.
Step 7 – Sauce Finish (2 min)
Splash in fish sauce and lime juice. The caramel foams, coats prawns, and turns sticky.
Step 8 – Toss & Plate (3 min)
Twirl noodles into bowls, spoon prawns and sauce over. Scatter mango, radish, herbs. Dust with chili-lime mix. Serve hot.
Troubleshooting
• Caramel seized? Add a spoon of hot water, re-melt.
• Sauce thin? Boil 30 sec longer.
• Noodles clump? Quick rinse under warm water.
Scalability: Double all quantities, same timings—use a wider wok.
Cooking Methods
• Rapid palm-sugar caramel for glossy glaze
• One-pan wok sear to keep protein moist
• Mortar-ground spice dust for last-second texture
Optional Spice Blend: Crushed toasted star anise with black pepper for extra warmth.
