In a saucepan, fry the onion with the pepper and add the whole peeled garlic. Let cook for five minutes over low heat.
Next, we put clove, salt and black peppercorns. Add the grated tomato and cook for four minutes.
We put the sofrito in the blender (except the garlic that we can throw it) and puree the mixture with a little water or chicken broth.
