How to Use Baking Ratios
Professional bakers think in ratios rather than fixed recipes. A ratio expresses the proportional relationship between ingredients by weight. Once you know the base ratio for a baked good (e.g. bread is roughly 5:3 flour to water), you can scale to any batch size, substitute ingredients intelligently, and diagnose texture problems. Weight (grams) not volume is the language of ratios.

The Formula
Bread (basic): 5 parts flour : 3 parts water : 0.1 parts yeast : 0.1 parts salt Cake (creaming method): 1 part butter : 1 part sugar : 1 part egg : 1 part flour Muffins: 2 parts flour : 2 parts liquid : 1 part egg : 1 part fat Shortcrust pastry: 3 parts flour : 2 parts fat : 1 part liquid Pancakes: 2 parts flour : 2 parts liquid : 1 part egg : ½ part fat
Variable Definitions
| Symbol | Name | Description |
|---|---|---|
| Part | Ratio Unit | One unit of weight (g or oz) — all ingredients are expressed relative to the same unit |
| Hydration | Hydration % | In bread, hydration = (water weight / flour weight) × 100. 60% hydration is a firm dough; 75%+ is a slack, open-crumb dough. |
Step-by-Step Example
Use the 1:1:1:1 cake ratio to make a cake using 200g of butter.

Solution
- 1All parts = 200 g:
1 part = 200 g - 2Butter:
200 g - 3Caster sugar:
200 g - 4Eggs (200 g ≈ 4 large eggs):

Common Mistakes to Avoid
Using volume instead of weight for ratios — cups of flour and cups of sugar weigh very different amounts, making volume ratios unreliable.
Skipping salt in bread — even a small amount (1–2%) is essential for flavour and gluten development.
Over-hydrating muffin batter — muffins should be mixed until just combined; over-mixing activates gluten and makes them tough.
Treating ratios as absolute — ratios define structure, but eggs, leavening, and flavourings need adjusting based on specific ingredients used.
