Sourdough Hydration — Why It Matters
Hydration is the ratio of water to flour in your dough. A 60-65% dough is firm and easy to shape; a 70-75% dough is sticky but bakes into a more open crumb.Use the calculator above: 500g flour + 350g water = 70%. Most artisan sourdough loaves sit between 65% and 80%.
Cake Serving Guide
Use the calculator for exact numbers — the rule of thumb: a round cake gives about 0.314 party servings per square inch of surface area.
| Cake Size | Party Servings | Wedding Servings |
|---|---|---|
| 6 inch | 9 | 5 |
| 8 inch | 16 | 9 |
| 9 inch | 20 | 12 |
| 10 inch | 25 | 14 |
