Serves 2Ingredients

Also mentioned in the method: pasta
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Bring a large pan of water to the boil and cook the linguine or spaghetti according to the packet directions until just tender, about 10 to 12 minutes.
While the pasta cooks, put the watercress, garlic clove, half the grated Parmesan, the toasted flaked almonds, the olive oil, lemon juice and sugar into a food processor or blender.
Blend until you have a coarse, spoonable pesto, scraping down the sides as needed. Add a splash of the hot pasta cooking water if it is too thick.
Drain the pasta, reserving a small splash of the cooking water. Return the pasta to the pan over low heat.
Add the pesto to the hot pasta and toss well, loosening with a little more reserved water if needed, until evenly coated.
Divide between two warm bowls and top with the shaved Parmesan and a few extra almonds if you like. Serve straight away.
