The planning notebook

Know what’s behind the number.

Practical guides to the assumptions that shape your shopping list.

Portions

Start with a portion size you know, then adjust for the meal you want to serve.

Scaling

One multiplier resizes the shopping list. The cooking method needs its own checks.

Value

A larger package can cost less per kilogram, but the arithmetic is only the first check.

Shopping

Turn a calculated recipe quantity into the amount you actually need to buy.

Worked example
