How to Use the Thawing Time Calculator
Choose a thawing method and enter the weight and thickness of the frozen food, then press Estimate Thawing. You get a rough time range in hours or minutes.
Safe ways to thaw
Fridge: plan ahead; allow roughly 24 hours per 5 lb (2.3 kg).
Cold water: submerge sealed food and change the water every 30 minutes.
Microwave: fine for defrosting, but cook the food straight away afterwards.
Never thaw food on the counter or in warm water.
