Portobello Mushroom 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 portobello mushroom varieties compare.

Variety	Best for
Portobello (Standard)	Burgers, grilling, and stuffing: mature brown cap with deep gills, dense and meaty when cooked.
King Oyster	Vegan scallops and steaks: thick white stems that take a sear; closest meaty substitute when portobello is out.
Lion's Mane	Vegan crab cakes and steak swaps: shaggy white clusters that pull apart into a tender, almost seafood-like texture.

Which should I pick?

For burgers, grilling, and stuffing, the standard mature Portobello cap is the pick: dense, meaty flesh that holds up under heat. No portobello? Thick-cut King Oyster gives a similarly meaty bite. For a vegan steak swap, Lion's Mane has a tender, almost crab-like texture.
