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

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.

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.

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.

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.
