How many egg whites make a cup
One large egg white weighs about 30 g, or 2 tablespoons, so it takes roughly 7–8 large whites to fill a cup (about 243 g). That's handy when you're baking from cartoned liquid whites or scaling a recipe up or down — instead of cracking and guessing, you can weigh to the exact amount. For meringues and angel food cake, weighing matters: too much or too little white throws off the structure.
| Amount | Large egg whites |
|---|---|
| 1 cup (≈243 g) | 7–8 whites |
| ½ cup (≈122 g) | about 4 whites |
| ¼ cup (≈61 g) | about 2 whites |
