Quick diagnosis: Surface energy is too intense for the time heat needs to reach the centre. Lowering heat or using a two-stage method restores control.
What the Symptoms Tell You
Exterior becomes dark or bitter while the centre remains cold, raw or firm.
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:
- Portions were too thick or very cold.
- Pan, grill or oil was too hot.
- Sugar or coating browned faster than the centre cooked.
Professional Rescue Method
- Move food away from direct heat.
- Finish with gentler oven or covered heat when the method allows.
- Discard severely burnt coating and verify the centre safely before service.
Safety and Quality Limit
Never serve a raw unsafe centre. Avoid holding partially cooked food for later completion unless an approved process exists.
Prevent It Next Time
- Standardise thickness and temper only under safe procedure.
- Use sear-then-finish methods.
- Measure centre doneness, not colour alone.
Chef’s Verification Test
Check the thickest centre and surface separately; both must meet the intended quality and safety target.
