Walnuts (Halves)

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.

Toast lightly for granola, pesto, brownies, or to finish roasted vegetables.

Storage & tools

• Refrigerate perishable foods within 2 hours (1 hour if above 90°F/32°C).
• Keep the refrigerator at or below 40°F (4°C) and the freezer at 0°F (-18°C).
• Cool hot foods in shallow containers so they chill faster and more safely.
• Use an appliance thermometer to verify fridge and freezer temperatures.

Keep airtight; refrigerate or freeze to prevent oils going rancid.

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.
