Yum, yum, yum. This needs no other introduction than that.
Start with about 1.5 ounces of dried porcini mushrooms. Soak them in about 2 cups boiling water for at least an hour.
Finely chop half an onion. I prefer red onions, or sweet onions when I can find them. Remove the mushrooms from the water, squeezing the excess from them. Reserve all the liquid. Chop the mushrooms.
Saute the onion in a bit of olive oil with about 4 cloves minced garlic. When the onion is translucent, add more olive oil and add the mushrooms. I used about 4 tablespoons of olive oil, in total. Saute a few more minutes.
Add your seasonings. I use sea salt, fresh black pepper, and a bit of marjoram. Add some thickly sliced portobello caps and sautee a few minutes until the portobello’s are starting to release their liquid.
Add enough of the reserved soaking liquid to make it like a sauce. I usually put all or most of it in and cook it down a little bit, then add parmesan cheese if it seems too thin. The parmesan thickens it up.
I know this recipe is very inexact – like most of my recipes! – but it’s hard to screw it up.
Best served over ravioli.
