How to make this recipe
- Light a grill or preheat a grill pan. Brush the lemon slices with oil and grill over high heat, turning once, until lightly charred, 2 to 3 minutes total. Transfer to a cutting board and let cool. Finely dice the lemon.
- Meanwhile, in a large saucepan of salted boiling water, blanch the broccoli rabe until tender, about 3 minutes. Drain and cool under running water; drain again. Transfer the broccoli rabe to a food processor and puree until smooth. Scrape the puree into a measuring cup (you should have about 1 cup).
- In a medium saucepan, bring the vegetable stock and 2 cups of water just to a boil; keep warm. In a large saucepan, melt 4 tablespoons of the butter. Add the onion, garlic and a generous pinch of salt and cook over moderate heat, stirring occasionally, until softened, about 5 minutes. Add the rice and cook, stirring, until coated and opaque, about 3 minutes. Add the wine and cook, stirring, until absorbed, about 7 minutes. Add half of the warm vegetable stock and cook over moderately low heat, stirring, until nearly absorbed, about 7 minutes. Add the remaining vegetable stock and cook, stirring, until nearly absorbed and the rice is al dente, 8 to 10 minutes longer.
- Stir the broccoli rabe puree into the risotto along with the grated Parmigiano-Reggiano cheese, tarragon, parsley and the remaining 2 tablespoons of butter. Cook, stirring, until the risotto is creamy and heated through, about 3 minutes. Season the risotto with salt and pepper. Spoon into shallow bowls and top with the chopped grilled lemon and dollops of mascarpone.
The broccoli rabe puree can be refrigerated overnight.
Northern Italian white wines have a refreshing brightness that mitigates the bitterness of green vegetables.
