Chives provide a mild onion flavor and are best used fresh and added at the end of cooking. They don't caramelize or develop depth like cooked onions, so use half the amount and adjust for freshness.
Garlic is much more potent than onion; use sparingly and adjust to taste. Best in cooked dishes where its pungency mellows.
Green onions are much milder and fresher; use slightly less and add near the end of cooking to preserve flavor. Better for garnish or fresh applications than deep flavor building.
Leeks are milder and slightly sweeter than onions; use equal volumes but use the white and light green parts only, and clean thoroughly as they trap soil between layers.
Direct substitution by volume. Smaller pieces cook faster and distribute flavor more evenly through the dish.
Blend fresh onions into a smooth paste. Use half the volume; intensity is stronger and distributes very evenly in sauces.
Use 1/4 teaspoon onion powder per medium fresh onion (or about 3-4 tbsp per cup). Powder is much more concentrated; best for soups, sauces, and dry rubs rather than dishes needing texture.
Roasting reduces onion moisture and concentrates sweetness. Use 25% less by volume; flavor becomes mellower and caramelized.
Scallions are milder and less dense; use 50% more by volume. Best used raw or added near the end of cooking to preserve their fresh flavor.
Spring onions are milder and less dense than regular onions; use slightly more and add them later in cooking to preserve their delicate flavor.
