Hello,
They should be frozen before frying.
Once the cakes are shaped, open-freeze them until solid, then store in polythene or a plastic container. Cook from frozen, allowing an extra 10 minutes’ cooking time for defrosting. Alternatively, defrost in the fridge overnight before cooking.
They can be stored in the freezer for up to 3 months
Best wishes
