Freezing does not improve food. It pauses it. Whatever quality goes in is the best you will get out, so freeze things at their best, not when they are about to turn.
- Cool it first. Never put hot food straight in the freezer. It raises the temperature of everything around it and can push other items into an unsafe range. Cool it quickly — shallow containers, not one deep pot — then freeze.
- Portion before freezing. A single block of four servings means you must defrost all four. Freeze in the size you will actually use.
- Get the air out. Freezer burn is dehydration. Wrap tightly, press the air out of bags, fill containers close to the top.
- Label everything with what and when. Every unlabelled bag becomes a mystery you will eventually throw away.
- Defrost in the fridge, not on the counter. It takes longer and it is the only method that keeps the food out of the temperature range where bacteria multiply.
Rough timings for best quality: cooked meals 2 to 3 months, raw meat 4 to 6 months, bread 3 months, soups and stocks 3 months. These are quality guidelines, not safety limits — food kept properly frozen stays safe, it just stops tasting good.
