This is a quick and easy recipe, a must-make when you have leftover risotto. It's almost a reason to make extra; that's how good they are. You can easily double or triple this recipe.
Mix 2 cups leftover risotto with ½ cup grated sharp cheese in a bowl.
Make four patties with the cold risotto, about 1 inch high.
On a shallow plate, put ¾ cup flour and season with ¼ teaspoon salt and black pepper to taste. Stir to combine.
Add the risotto cakes and coat them on both sides, lightly shaking off excess.
Melt 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-low heat.
Add the floured cakes in a single layer and cook slowly, until very crisp, about 4 minutes on each side. If browning too quickly lower the heat. You want the heat to reach the center of the cakes and melt the cheese.
Have paper towels ready and blot them before serving.
Place the cakes on a serving platter or wooden board and serve immediately with 4 lemon wedges and some greens.
