Decide your cooking method (sauté, roast, simmer) and whether you need a mild flavor or a deeper one.
Pick the substitute from the WPRM list that matches your texture goal: closest bite, meaty bite, tender fast-cook, or canned for stews.
Use the listed ratio: start with the same amount as button mushrooms, then adjust for intensity (shiitake) or moisture (canned).
Cook in the same time window as button mushrooms, but add tender mushrooms (like oyster) a little later.
Taste at the end and adjust seasoning: add a pinch of salt for muted brands or a small splash of broth for dryness.
