Why halving a recipe goes wrong
Halving 2 cups is easy. Halving ¾ cup or⅓ cup is where recipes fall apart — the answer isn't a measuring cup you own. The trick is converting to tablespoons: a cup is 16 tablespoons, a tablespoon is 3 teaspoons, so every awkward fraction turns into spoons you actually have. That's exactly what this site does for you, for every amount a recipe can throw at you.
One thing to watch: eggs and leaveners don't scale neatly. Half a recipe calling for one egg means whisking an egg and using half (about 2 tablespoons). And when doubling baked goods, scale baking powder and soda to about 1¾× rather than a full 2× — doubling them exactly can leave a metallic taste.
