The halving problem
Most quantities halve cleanly, but some do not: 1/3 cup becomes 1/6 cup, which no measuring set includes. The tool rounds to the nearest measurable fraction and shows the exact decimal underneath, so you can decide between 2 tbsp + 2 tsp and a scale.
Workarounds that actually work
- 1/6 cup: use 2 tbsp + 2 tsp
- Half an egg: beat one egg and weigh 25 g, or use 1 yolk + 1 tbsp water for binding
- Tiny amounts: below 1/8 tsp, use a pinch — precision past that is imaginary
- Scale instead: a 0.1 g kitchen scale beats any fraction for small quantities
When halving fails
Custards, mousses and breads are ratio-sensitive: halving the volume changes how heat penetrates and how gluten develops. For a cake, a smaller tin at the same depth works better than halving the batter into the original tin.
Single-person cooking
Halving is the standard move for cooking for one, but consider making the full batch and refrigerating or freezing portions — the effort is nearly identical and the second meal is free.
Frequently Asked Questions
How do I halve 3/4 cup?
3/8 cup, which measures as 1/4 cup + 2 tbsp.
Can I halve a recipe with one egg?
Yes — beat it and use half by weight (about 25 g), or substitute 1 yolk plus a tablespoon of water.
Why does halving change the texture?
Smaller volumes heat faster and lose moisture differently; expect shorter bake times and sometimes a denser crumb.
