Onion (Chopped): How Many Grams in a Teaspoon?
'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.
