This is from a website called something like Thorngrove - back with the link in a minute. (Lots of parsley pesto recipes on google). A lot of them have lemon in the ingredients, though this one doesn't happen to.
Flatleaf Parsley & Walnut Pesto
It occurs to me I should mention that I sent my Euro Blogging By Post parcel to Austria, into the hands of Gerda of Dinner for One. Amongst the items was a jar of home-made Flatleaf Parsley & Walnut Pesto, one of my favorite dressings for pasta. Pesto can actually be made from herbs other than basil, and I encourage you to try different ones out. Once you get over the shock of the new I think you'll find them delicious. Gerda wrote to say she and her friends thought this was "incredible" (yes! converts!) and could I post the recipe. I tend to improvise a bit with pesto as it varies depending on what I have to hand, but here's prettymuch what I did for that batch:
Flatleaf Parsley & Walnut Pesto
1 really big bunch of Italian Flatleaf Parsley
2 large pinches of Maldon Salt or Sea Salt
2 cloves of Garlic, crushed
4 Tb Parmesan, grated
2 Tb Pine Nuts
3 Tb Walnuts
1 Tb soft Butter
1/2 cup Olive Oil*
Put half the parsley, salt and garlic in a food processor and whizz it around until finely chopped.
Traditionally you break up the herbs with a mortar & pestle, but that really doesn't work for parsley...
Add the rest of the parsley, salt and garlic and whizz until combined finely.
Crush the walnuts and pinenuts in a mortar and pestle, reserving 3 or 4 or the walnuts.
Add the cheese, nuts and butter to the mixture bit by bit, whizzing until combined.
Very very slowly, dribble in the oil, whizzing until the mixture is a fine blended paste. This should take a while to ensure the oil is completely mixed in.
Break the remaining walnuts into small pieces and add to the finished pesto for a bit of texture - this step is optional.
Put pesto in a cooled sterilized jar** (so the pesto doesn't accidentally cook) and cover the top with half a centimetre of oil.
This should keep it good without refrigeration for at least a month. Once open, refrigerate and eat within 4 days.
