An easy recipe: Ragusan red pesto

Here's a recipe a great sicilian cook gave me. It sounds pretty easy and delicious
(serves 4 people):

Ingredients:
You will need 10 fresh basil leaves, 1 garlic clove, 30 gr. of pinenuts, ½ teaspoon of concentrated tomato paste, 2 ripe tomatoes, 5 tablespoons of ricotta cheese, extra virgin olive oil, salt and grated parmesan cheese to taste. You can add sun dried tomatoes (optional)

Preparation:
Peal and remove the seeds from the tomatoes, springle with salt and leave for about half an hour so they loose some of the juice. Blend tomatoes with pinenuts, garlic and basil. Add olive oil and 2 tablespoons of sun dried tomatoes (optional). Mix the pureed ricotta cheese with the pesto mix from the blender (do not add ricotta to the blender). Serve as a topping for pasta and sprinkle with grated parmesan cheese.
