How to make
Blanch the almonds in hot water, by keeping them in the water for no more than 1 minute. The peel is then removed from each almond.
Cut an X on the bottom of the tomatoes with a knife. They are blanched for a few minutes in hot water, so that the peel can be removed afterwards. They are cut into larger pieces and the seeds are removed.
The almonds and walnuts are blended together. Add the garlic, basil, tomatoes, Parmesan and as much salt and black pepper as you like.
Everything is blended well. Then add the olive oil and tomato puree and blend again.
The spaghetti is cooked in salted water, then strained, by keeping some of the water.
The extra clove of garlic is finely chopped and the onion is cut into small pieces. Fry the onion in heated oil or butter, then fry the garlic with it.
Pour the pesto, pour a little of the water from cooking and mix. Add the spaghetti and mix well.
The spaghetti with homemade tomato pesto can be sprinkled with more parmesan when being served.
