Walnut halves vs chopped: why the cup differs
Walnut halves stack loosely, so a cup holds about 117 g, while chopped walnuts settle into the gaps and a cup weighs a little more. That's why a recipe's wording matters: 1 cup walnuts, then chopped, is less than 1 cup of already-chopped walnuts.
For the most reliable result, weigh them — and if a recipe just says 1 cup walnuts, measure them as halves and chop afterward.
