Shallot
Shallots are milder and sweeter than yellow onion. Use in dressings, pan sauces, and gentle stews; skip when you need the raw bite of a sharp onion. See our Shallot converter.
Spring Onion
Best raw: salsas, dressings, and garnish. Spring onion whites are much milder than yellow onion, so cook gently or you lose the allium entirely. See our Spring Onion converter.
Garlic
Mincing garlic for the same dish? Garlic cloves (2–7 g) bring pungent bite where onion brings sweet body. See our Garlic converter.
Radish
Want a crisp, peppery bite? Radishes (8–25 g) are sharp and crunchy, good raw in slaws or quick pickles. See our Radish converter.
Chopped Onion
Already chopping? The chopped onion converter moves straight between cups, grams, and spoons of prepped onion. See our Chopped Onion converter.
