Walnuts (Halves): How Many Grams in a Cup?
Walnuts are the classic example of volumetric inaccuracy. Due to their irregular shape, walnut halves create massive air gaps in a measuring cup. A cup of whole halves can weigh 30% less than a cup of chopped nuts. Weighing is the only way to ensure your banana bread is rich and nutty, rather than dry or sparse.

FAQ
- Toasted vs. Raw: Does weight change?
- Slightly. Toasting removes moisture (making them lighter by ~3-5%), but boosts flavor immensely. Ideally, weigh them raw as listed in most recipes, then toast.
- Should I chop before or after measuring?
- This is the 'million dollar question' of volume recipes. '1 cup chopped walnuts' usually means chop THEN measure. '1 cup walnuts, chopped' means measure THEN chop. Using a scale (grams) eliminates this linguistic confusion entirely.
