How much should you batch-cook? Scale a recipe and split fridge from freezer

Batch cooking is easy until you do the sums: a recipe for four is not a recipe for ten, and not every portion can wait in the fridge until Friday.

This planner scales a recipe to the number of portions you want, shows how many go in the fridge and how many in the freezer, and explains what scales (ingredients) and what doesn't (cooking times, seasoning). It follows UK and US food-safety guidance and the British Dietetic Association's freezing advice.
