Reading Recipes Critically
Judging whether a recipe fits the way you actually eat before you cook it.
Last revised
Key takeaways
- Stated portions: often smaller than people actually serve
- Salt: add at the end and taste; you can never remove it
- Most useful single change: Read the whole recipe before starting, including timings.
- Commonest mistake: Starting a recipe you have not read to the end.
- See a doctor if any of the signs under "When to get help" below apply to you.
Why it matters
A recipe is a set of assumptions about time, equipment and portions, and most failures are a mismatch rather than bad cooking.
The numbers, in one place
| Measure | Figure |
|---|---|
| Stated portions | often smaller than people actually serve |
| Salt | add at the end and taste; you can never remove it |
| Oil quantities | measure with a spoon rather than pouring |
| Substitution rule | swap like for like in structure, not only in flavour |
| Eatwell plate composition | about a third vegetables, a third starchy food |
What helps
- Read the whole recipe before starting, including timings
- Check the portion count against how much you will actually serve
- Add half the salt, taste, then adjust
- Add a vegetable to almost any recipe without changing the method
What to avoid
- Starting a recipe you have not read to the end
- Assuming a stated portion matches a real one
- Substituting ingredients that play a structural role, such as eggs in baking

When to get help
Check recipes carefully for allergens if you or anyone you cook for has a food allergy, and be aware of cross-contamination. If you have been given a therapeutic diet — low potassium, low sodium, carbohydrate counting — check substitutions with your dietitian rather than improvising.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
