To reconstitute the porcini, put the mushrooms in a bowl and pour hot water over them to cover, about 2 cups.
-
2
Soak until the mushrooms soften, 30 minutes.
-
3
Carefully lift the mushrooms out of the liquid with a fork, so as not to disturb the sediment settling at the bottom.
-
4
Coarsely chop the mushrooms; you should have about 3/4 cup.
-
5
Strain the porcini soaking water into a measuring cup through a coffee filter or a double layer of paper towels; you should have 1 1/2 cups.
-
6
Put a large skillet over medium heat and coat with 2 tablespoons of the oil.
-
7
When the oil is shimmering, add the onion.

Cook, stirring, until the onion begins to soften, about 3 minutes.

Toss in half of the garlic, all of the thyme and rosemary, and season with salt and pepper.

Add the chopped porcini, the tomatoes, and the short ribs.

Pour in the wine and continue to cook until the liquid has evaporated, roughly 10 minutes.

18
While the pasta is cooking, prepare the escarole.
