Ravioli with walnuts, goat’s cheese & cavolo nero sauce

Method

• step 1

  Bring a large pan of lightly salted water to the boil, then add the cavolo nero. Cook for 1-2 mins until the kale turns bright green and softens. Lift out with tongs into a colander, keeping the cooking water to boil the pasta. Run cold water over the kale, squeeze out any excess water, then transfer to a food processor. Add the oil, garlic, lemon juice and 1 tsp salt, then blitz to a fine pesto. Season to taste and transfer to a small pan. Gently warm over a medium-low heat.

• step 2

  Clean the food processor. For the goat’s cheese paste, tip in the nuts, sage, goat’s cheese, a good squeeze of lemon juice and the oil, then blitz to a paste. Season, then warm in another small pan over a medium-low heat, stirring occasionally.

• step 3

  Bring the pan of cavolo water to the boil again, adding more water if needed. Add the pasta sheets and simmer following pack instructions. Drain, keeping back a cup of the pasta water to add to the sauce (about 400ml). Cut the pasta sheets in half and toss in a little olive oil.

• step 4

  Stir the reserved pasta water through the cavolo sauce and keep on a low heat. If the sauce looks thick, thin down with a little more water, or increase the heat a little if too thin; it should be pourable like double cream. Spoon a pool of sauce onto each plate. Layer the lasagne sheets on top with spoonfuls of the goat’s cheese paste in-between each layer. Top with the last sheet of pasta and ladle over a little more sauce, then scatter over the cheese.
