Fresh to Dried Herb Converter

What drying takes: All of it — the raw green aroma is the whole ingredient.

Ratios and refusals from Fresh vs Dried Herb Conversion, and the cilantro profile. Volume ratios are a starting point; taste before you add more.

Every herb, and what it does when dried

Fresh to dried, by volume. "Stop" means the swap should not be made at all for that job.
