Paste a link to any recipe. Scappi reads it, leaves out the ads and the life story, and emails you a clean copy you can halve, double or scale to any number of servings, in US cups and spoons or metric.
Multiplying every amount gets you most of the way. These are the parts that need a little more thought.
Cups and spoons pick up small errors, and scaling multiplies them. Grams stay accurate at any size, which matters most for flour, sugar and butter.
Eggs, cans and packets rarely divide evenly. Round to the nearest whole one, and adjust liquid a little if you rounded down a large egg.
Salt, chili and strong spices don’t always need the full multiple. Add about three quarters of the scaled amount, taste, and add the rest if it needs it.
A doubled batter in the same pan is deeper and bakes differently. Use a larger pan or two pans so the depth stays close to the original.
Oven temperatures stay the same. A larger roast or a deeper pan needs more time, but not twice as much, so start checking early and go by doneness.
Baking powder, soda and yeast scale with the recipe for a double or triple batch. Much larger batches are better made as several smaller ones.
When you only need one amount, this is what the common measures come to. The recipe converter above does every ingredient at once, for any number of servings.
| The recipe says | Half | Double |
|---|---|---|
| 1 cup | ½ cup | 2 cups |
| ¾ cup | 6 tbsp | 1½ cups |
| ⅔ cup | ⅓ cup | 1⅓ cups |
| ½ cup | ¼ cup | 1 cup |
| ⅓ cup | 2 tbsp + 2 tsp | ⅔ cup |
| ¼ cup | 2 tbsp | ½ cup |
| 1 tbsp | 1½ tsp | 2 tbsp |
| 1 tsp | ½ tsp | 2 tsp |
| ½ tsp | ¼ tsp | 1 tsp |
| 1 egg | Half a beaten egg, about 25 g | 2 eggs |
A cup is 16 tablespoons and a tablespoon is 3 teaspoons, which is where the odd halves come from.
The recipe you get by email opens on the web, where you can scale it and switch units. In the Scappi app the original recipe is always one tap away, and you can also adapt it to your taste, cook it step by step with timers, and keep it with all your other recipes, always available.
