Quick diagnosis: Prawns tighten as proteins coagulate. A gentle C-shape is usually earlier than a tight O-shape, but size and species still require proper verification.
What the Symptoms Tell You
Prawns form tight rings, become dry and resist biting.
Why This Usually Happens
The most common causes are connected to temperature, ratio, timing, ingredient condition or technique. Compare the dish with these specific checks:
- They cooked too long or remained in hot sauce.
- Sizes were mixed.
- Carryover and reheating were ignored.
Professional Rescue Method
- Remove from heat and hot liquid immediately.
- Serve with moist sauce or chop for a filling.
- Do not boil longer; toughness will increase.
Safety and Quality Limit
Use approved sourcing and safe cooking guidance; colour and curl alone cannot establish safety.
Prevent It Next Time
- Sort by size and add late.
- Cook in a single controlled batch.
- Remove just before final carryover completes.
Chef’s Verification Test
Cut the largest prawn: flesh should be appropriately opaque and moist, not glassy or dry.
