Using the logic that the best way to fake an expensive mushroom is to use an inexpensive mushroom with a dubious transfer of flavor. Please spare us the lecture on the integrity of ingredients with the comments,that is not the point of this post. This is just plain silliness in the kitchen.
Porcini : Expensive-Highly Perishable.
Royal Trumpet : Dirt Cheap-Keeps well.
The story goes…..
Sonicate slightly steamed dry Cepes into 90% Grapeseed-10% Hazelnut Oil.
Pack the oil and Royal Trumpets into a vacuum pouch.
Cook in the bath.
Cool.
Remove from pouch and wipe clean.
Slice, season with salt and Sear in a pan.
It tastes like and has the texture of a pretty good Porcini.
