It will require a lot of vegetables: at least a couple of generous bunches of fresh basil, natural cheese, 200 grams, half a glass of olive oil and walnuts (walnuts / pine nuts), a little garlic to taste, 2 cloves are recommended.
Chop the veggies, mince the nuts and garlic, grate the cheese, or mix everything directly in a blender / food processor. When everything is chopped, add the butter, continue to beat until smooth and thick enough. Salting is not necessary, the richness of the vegetables and the specificity of the nuts, seasoned with a note of garlic, create a composition of sufficient and quite intense flavor.
For fruit cheese sauce, you need honey, almonds, lemon juice, delicate soft cheese, vanilla, nutmeg. The ingredients are mixed well until smooth. For meat or fish dishes, the cheese sauce recipe suggests a spicier and more spicy cheese, complemented with additives of tomato, mustard, spicy note or lemon, curry, slightly harsh aromatic herbs (parsley, rucolla, onion), curry and peppers.
You can just experiment ad infinitum. Or you can make a basic sour cream cheese sauce and dilute, try various combinations right at the table.
