Method
Each step includes heat, a visible cue, and a recovery.

Step 1 · follow the visible cue
Prepare the measured ingredients
Give the different textures their own space: large prawns, unsalted butter, and curry leaves. Match the listed amounts, prepare each for its own cooking time, and keep wet components away from ingredients that need a dry surface.
Look for: The first checkpoint is large prawns, unsalted butter, and curry leaves are evenly prepared, accurately measured, and free of unintended surface water.

Step 2 · follow the visible cue
Build the defining flavour
Layer in bird's-eye chilli, garlic, and evaporated milk. Add them in a deliberate order so strong aromatics soften without burning and delicate notes remain noticeable in Butter prawns.
Look for: The second checkpoint is bird's-eye chilli, garlic, and evaporated milk smell rounded and remain recognisable, with no black flecks, raw spice aroma, or separated fat.

Step 3 · follow the visible cue
Cook with controlled heat
Keep the richest part controlled while you sear dried prawns quickly, toast oats and aromatics in a measured amount of butter, then return the prawns for one final toss. Regulate heat and exposed moisture throughout this stage instead of correcting the texture later with extra oil, sugar, or sauce.
Look for: The cooking checkpoint is prawns form a loose C shape with browned shells, while the crisp oat crumbs remain separate and dry. Check the thickest or coolest part rather than judging only the browned surface.

Step 4 · follow the visible cue
Finish and verify the texture
To preserve contrast, add oats and lime. Stop when prawns form a loose C shape with browned shells, while the crisp oat crumbs remain separate and dry, allow only the rest required for the structure to settle, and divide Butter prawns evenly into two portions.
Look for: The serving checkpoint is Butter prawns holds its intended shape and prawns form a loose C shape with browned shells, while the crisp oat crumbs remain separate and dry; no excess liquid, fat, or loose coating collects around the serving plate.
