Spring Onion varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common spring onion varieties compare.

Variety	Best for
Scallion (green onion)	All-purpose use raw or cooked: mild, crisp, and fresh; the standard supermarket spring onion.
Welsh onion (negi)	Stir-fries and cooked dishes: more pungent and heat-tolerant than common scallions.
Bunching onion	Asian dishes and pickling: slightly bulbous base, bold flavour, very versatile.

Which should I pick?

For most recipes (stir-fries, salads, soups, and garnishes) a standard scallion (green onion) is the default: mild, fresh, and edible from root to tip. Welsh onions are more pungent and hold up better to heat; use them when you want stronger flavour in cooked dishes. Bunching onions have a slightly bulbous base and bolder flavour: the everyday choice in many Asian cuisines.
