Onion (Chopped)

'One medium onion' is cooking's vaguest measurement: it can range from 100g to 300g. For a soup, it might not matter, but in sauces, meatballs, or fillings, excess onion releases water that can ruin the texture. Weighing chopped onion gives you total control over flavor and moisture.

Weigh for sautés, soups, and sauces to balance aromatics.

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.

Refrigerate sealed; use within a few days to avoid sulfur odors spreading.
