“Small, medium, large. That’s apparel size,” states vegetable expert and also cookbook writer Deborah Madison. “Vegetables nothing come small, medium, large.”

While over there are definitions using weights and also diameters in “The book of Yields” and also “The Chef’s publication of Formulas, Yields and Sizes,” the usual home cook isn’t lugging a size chart under the develop aisle. And when it comes to cookbooks, one author’s medium could be another’s large, and also so on. Medium might be the smallest you can find of certain vegetables anyway.

Madison, bless her heart, is someone who provides the effort to shed a tiny light ~ above what she method when she describes sizes. Leaf v her publication “The new Vegetarian cooking for Everyone” and you’ll find with every vegetable’s information page, a discussion of average sizes and what she method when she calls because that a particular size.

But no every cookbook writer or various other recipe source is as diligent, and not every recipe provides an identical volume or weight as soon as specifying a specific size. What then?

A little much more carrot in her minestrone, a tiny less onion in your fajitas — the okay. After all, among the an excellent things about savory food preparation — as opposed come baking — is the capability to tweak a recipe without damaging consequences.

If she in find of tiny produce, either since of a cooking recipes or the variety of people in her house, your best bet is a farmers market. As soon as I went to one downtown D.C. Industry recently, I found everything from very tiny onions and also peppers to huge tomatoes and also squash. One vendor’s eggplant an option alone included tiny Fairy Tales, slender Asian and the timeless Italian, varying in dimension from small to extra large (according to my own personal definitions, that course).

Even putting in the effort, your find for a small or tool head the cabbage, for example, might fail. In that case, try to be creative with leftovers. “It’s okay to eat the exact same vegetable much more than one day,” Madison says. Just don’t let them languish in your create drawer.

More than anything, she says, “I just want civilization to relax. … Recipes aren’t yes, really necessarily collection in stone.”
