Place the blanched almonds in a dry skillet/frying pan over a medium heat and toast until lightly brown on both sides. Place them in a food processor and pulse until relatively fine crumbs.
Meanwhile, lightly prick the skin of the tomatoes in a few places. Put the tomatoes in a bowl and pour over boiling water and leave for a minute or two until the skin starts to peel away where you have pricked the skin.
Take the tomatoes out of the hot water and remove all of the skin. Cut the tomatoes in half, remove the core and roughly dice.
Peel the garlic and roughly chop. Add the tomatoes, garlic, basil, pecorino cheese and oil to the ground almonds and pulse to bring the mixture together.
Stir through pasta of your choice, cooked al dente, and top with a little additional pecorino.
Notes
This quantity of sauce works with around 12oz - 1lb pasta (375-500g), serving 3 to 4 people, depending on how thickly sauce-covered you prefer it.I didn't use any mint in the pictures here as I didn't have any, but it appears in many recipes and will add that bit of extra freshness.
