A 3-egg recipe is the classic reason people give up on half batches. The ingredient factor is simple: ×0.5. The egg line becomes 1.5 eggs, which means one whole egg plus half of another egg. You do not need a special tool; you need a fork and, ideally, a scale.
The scaling ratio
Half of 3 eggs is 1½ eggs. A US large egg is about 50 g out of the shell, so half a large egg is about 25 g of whisked whole egg.
Quick reference
Use this egg table when scaling recipes with large eggs.
| Original eggs | Half batch | How to measure |
|---|---|---|
| 1 egg | ½ egg | 25 g whisked egg |
| 2 eggs | 1 egg | Use one whole egg |
| 3 eggs | 1½ eggs | One whole egg plus 25 g whisked egg |
| 4 eggs | 2 eggs | Clean split |
| 5 eggs | 2½ eggs | Two whole eggs plus 25 g whisked egg |
The clean half-egg method
- Crack one egg into a small bowl and whisk until no streaks remain.
- Set a second bowl on the scale and tare it.
- Pour in 25 g of the whisked egg for half an egg.
- Save the rest for egg wash, scrambled eggs or another small recipe.
Worked example: half of a 3-egg muffin recipe
Original: 3 eggs · 2 cups flour · 1 cup milk · ½ cup oil · ¾ cup sugar. Half batch: 1½ eggs · 1 cup flour · ½ cup milk · ¼ cup oil · 6 tbsp sugar.
Use one whole egg plus 25 g whisked egg. Muffin bake time stays close to the original if each muffin cup is filled to the same level.
Egg shortcuts and where they work
- Using only a yolk is not the same as using half an egg; it adds fat without the white's structure.
- A small egg can work in pancakes or meatballs, but it is too rough for delicate cakes.
- Whisk thoroughly before weighing so the half egg includes white and yolk in the right balance.
- Refrigerate leftover whisked egg promptly and cook it fully when you use it.
