Step 1

Begin by making the Simple tomato sauce, heat the olive oil in a saucepan, add the garlic clove and cook until just softened. Add the chopped tomatoes and season. Cook slowly for 25 mins, stirring now and then, until very thick. Do this a day or two ahead of assembling the rotolo, or freeze it for up to 2 months.

Step 2

Wilt the spinach in a pan over a medium heat, then leave to cool. Squeeze well to remove the excess water, then roughly chop the spinach. Season and leave to cool completely.

Step 3

Gently fry the garlic in the butter until softened, then remove from the heat and add the marjoram. Tip into a bowl and add the spinach, ricotta and Parmesan.

Step 4

Roll out the pasta (see step-by-step images). Cut the sheets into 3 or 4 pieces, each roughly 40cm long, and place them on a white tea towel. Using a little water and a pastry brush, stick the sheets together, allowing a 1cm overlap.

Step 5

Using a spatula, spread the filling over the pasta as evenly as possible, leaving a 1cm border around the edge.

Step 6

Fold over the edge of the pasta nearest to you and, using the tea towel and the weight of the pasta, roll it away from you like you would a Swiss roll.

Step 7

Brush the open edge of the pasta with a little water and press together to seal.

Step 8

Wrap the pasta roll tightly in the tea towel and tie a piece of string round it every 10cm or so (or use a butcher’s knot – see step-by-step images). Tie the ends with string to secure them, leaving a long piece of string at each end to act as a handle.

Step 9

Bring a large pan of salted water to the boil (a fish kettle is ideal, but a deep roasting tin filled with water works well too) and cook the rotolo for 20 mins. Remove from the water and leave to cool. Heat oven to 190C/170C fan/gas 5.

Step 10

Gently unwrap the rotolo and cut it into 3cm slices. Arrange the slices in a baking dish. Spoon over the Simple tomato sauce, sprinkle with Parmesan and drizzle with a little olive oil. Bake for 15 mins until the pasta is hot and crisping around the edges.
