Reading Recipes Critically: What to Do, in Order
Reading Recipes Critically: what is worth doing, what is worth avoiding, and when to stop and see a doctor.
Judging whether a recipe fits the way you actually eat before you cook it. A recipe is a set of assumptions about time, equipment and portions, and most failures are a mismatch rather than bad cooking.
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 speak to a doctor" below apply to you.
Do
- 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
Do not
- 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
The numbers behind the list
The list is built from the numbers below, which come from the bodies cited at the end.
| 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 |
If you change one thing
Read the whole recipe before starting, including timings. It heads the list. If you take nothing else from this page, take that.

When to speak to a doctor
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.
