Angelo McDonnell, executive chef of the Igor's Group, focused on one ingredient for his recent book, Hot Tomatoes. He incorporated the fruit, which comes in more than 4,000 varieties, in every recipe in the book.

Lay the sliced Serrano ham on a baking tray lined with parchment paper. Bake at 100 degrees for 30 minutes, or until crisp. Bring a large pot of salted water to the boil. Blanch the tomatoes in the boiling water for five seconds then drain them and plunge into iced water. Remove the skins. Combine the ingredients for the dressing, stirring in the truffles at the end. Toss the tomatoes with 150ml of the dressing then divide into bowls or cups with the salad greens and crispy ham, and serve.

Heat the oil in a skillet and when the pan is very hot, sear the chops on both sides.

Spoon the balsamic cherry tomatoes onto plates and top with the lamb chops. Garnish with parsley and fried tomato.

Cook over a low heat for one hour, stirring frequently. Taste for seasonings and adjust if necessary. To make the gnocchi, bake the potatoes at 180 degrees until tender. Peel the potatoes then put the flesh through a food mill. Add about 200 grams of flour, the egg yolks, tomato paste, 60 grams of butter, the breadcrumbs and salt and pepper, to taste. Mix until it forms a dough; if it's sticky, add more flour. On a lightly floured surface, roll the dough into a long snake, cut into even pieces and roll them between your hands to form small finger shapes. Bring a large pot of salted water to the boil and poach the gnocchi - they're ready when they float to the surface. Drain then saute them in a skillet with 15 grams of butter. Whisk together the ingredients for the mascarpone cream. Spoon the gnocchi into bowls, top with the mascarpone cream and conpoy and garnish with crisp basil leaves.
