For the tagliatelle with walnut-sorrel pesto, first cook the tagliatelle until al dente.
Crack the walnuts and peel off the skin, grind in a mortar – DO NOT roast! Wash parsley and sorrel, pat dry and chop finely. Put both in a mortar and grind with olive oil and grated parmesan. If you like it spicier, you can season the pesto with salt and pepper. Arrange the tagliatelle in a deep plate, add the pesto and enjoy the tagliatelle with walnut-sorrel pesto.
Preparation Tip:
Fresh walnuts are very easy to peel and have a very intense flavor, roasting would soften this flavor. Together with the sorrel makes for the tagliatelle with walnut-sorrel pesto a very great combination.
