To freeze or not to freeze?

Filo pastry
It can be frozen, but dries out very quickly and becomes harder to work with. YES if you’re scrunching on top of a fish pie (like our filo-topped fish pie). NO if you’re using to make parcels or samosas.

It can be frozen, but once defrosted, the texture can become grainy. YES if you’re freezing small amounts that can be splashed into a sauce. NO to whole tubs.

Although most pack information says YES, we say NO if it’s for a cheeseboard, but YES if it’s for cooking.

What is freezer burn?

Food that has not been covered properly during freezing will dry out and turn white in patches. Freezer burn may affect the quality of the food, but it is still safe to eat.

Good to know

  • The recommendations above are for a three-star rating freezer, which should be kept at -18C. If your freezer is kept at a higher temperature, food will deteriorate faster.
  • It’s important to label frozen foods with the contents and date they were frozen. Sticky labels often come unstuck in the freezer, so pop labels inside the food bag.
  • Never refreeze frozen food (unless it’s been cooked into another dish) – this can encourage bacteria to multiply to dangerous levels.
