Common mistakes to avoid with pecans

  • Measuring whole pecans and chopped pecans as equivalent — chopped pecans pack more densely and weigh significantly more per cup.
  • Using stale pecans that have gone rancid — store in the freezer for maximum freshness.
  • Toasting pecans at too high a temperature (above 175°C / 350°F), which burns the natural oils quickly.
