To flash-freeze is to freeze produce very rapidly, just after it has been picked or caught — the quality strategy of the frozen-food industry at its best. Peas travel from field to freezer in hours; fish are frozen on the boat; berries go from bush to blast freezer the same day. The speed matters because ice-crystal size decides texture: flash freezing forms crystals too small to rupture cell walls, so the thawed food keeps its structure, colour, and much of its fresh flavour. The “just after picking” is as important as the speed — freezing locks in the harvest moment, halting the enzymatic and microbial decline that starts immediately. Flash-frozen at peak ripeness often beats “fresh” produce that spent a week in transit — the freezer as a time machine for harvest day.
