Why measuring walnut halves by cup goes wrong
Walnut halves weigh about 100 grams per cup. Chopped walnuts pack tighter — a cup of finely chopped weighs closer to 115 g. The same applies to most tree nuts: the smaller the pieces, the heavier the cup.
Practical tips for working with walnut halves
Chop walnuts before you measure them if the recipe says 'chopped walnuts.' Measuring halves and then chopping changes the actual quantity by 15 percent. Toast chopped walnuts at 350 °F for 6 minutes; they go from raw-tasting and faintly tannic to warm, deeply nutty, and lightly crisp. Cool completely before folding into batter or they'll melt the butter.
Note from this ingredient's record: Halves and pieces. Chopping them drops volume by about 15 percent — chop first, then measure if you want consistency.
