- Place porcini in small bowl. Pour enough boiling water over just to cover. Let stand until mushrooms soften, about 30 minutes. Rinse and drain well. Chop mushrooms and reserve.

Add porcini mushrooms and chopped carrot and simmer until risotto is very thick (wooden spoon drawn across bottom of pan will leave wide path) and rice is tender, stirring frequently and adding remaining chicken broth by 1/4 cupfuls if rice needs additional cooking, about 18 minutes. Mix in Pecorino Romano cheese and chopped tarragon; season risotto mixture to taste with salt and pepper. Transfer to bowl. Mix in egg. Cover and refrigerate overnight.
- Form mixture into six 3- to 3 1/2-inch-diameter patties, using about 1/2 cup risotto for each. Melt 1 tablespoon butter in large nonstick skillet over medium heat. Add risotto patties and cook until brown, about 5 minutes per side. transfer risotto cakes to plates. Garnish with tarragon sprigs and carrot curls.
