I discovered frozen mixed mushrooms (apparently with some pieces of porcini in it, but I couldn’t see many). In any case, unable to forage now, these looked good to me.
I used a 300g bag of frozen mixed mushrooms
30g dried porcini mushrooms,
a few garlic cloves
The dried porcini mushrooms need to be soaked for a an hour or so.
Sauté the garlic with the olive oil, add the frozen mushrooms, and after five minutes the porcini mushrooms and their soaking water. Add the tomato passata (about a cup) and simmer for 30 minutes. Stir often and add water if necessary. Add salt to taste.
I served these mushrooms with polenta, and then, since I had a few left over, I made some pasta the day after, but I'll talk about that tomorrow!
