Spinach 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 spinach varieties compare.

Variety	Best for
Baby Spinach	Salads, smoothies, and quick sautés: tender small leaves that need no prep and wilt evenly.
Savoy Spinach	Cooked dishes, soups, and stews: crinkled leaves with a robust texture that holds up to long cooking.
Flat-Leaf Spinach	All-purpose cooking and fresh use: large smooth leaves that work raw or cooked.

Which should I pick?

Baby spinach suits most recipes, raw or cooked: tender leaves that need no trimming and wilt evenly. Flat-leaf is the all-purpose pick when baby spinach is unavailable, working raw in salads or cooked in pasta and curries. Save crinkled savoy for long-cooked soups and stews, where its robust texture holds up better than tender leaves.
