Pecans are light — weigh them for baking
Pecans are one of the lightest nuts by volume: a cup of halves is only about 99 g. Chopped pecans settle denser, so a cup of chopped weighs a little more than a cup of halves. For pie and cookie recipes that live or die on the nut amount, weighing is the safest bet.
A quick toast at 350°F for 7–9 minutes brings out their buttery flavor before you fold them into batter or press them onto a pie.
