Let's talk Porcini Mushroom Powder.
I recently ordered some from The Spice House.I debated about a few uses but had read that in a burger seasoning, the porcini powder offered depth and richness that many seasonings do not support. I tried it. Very successful!
1 pound ground grass-fed beef
3/4 teaspoon porcini mushroom powder
Mix ground beef and divide into patties. Grill over medium-high heat until desired temperature is reached.
