Some may think its silly to grow your own sorrel when you have it growing wild just around the corner. Well in Sweden they warn you not to eat the wild sorrel as it contains too much oxalic acid to be healthy. I don’t think that’s a worry when it comes to the milder cultivated sorrel, but I’m not sure.

Anyway this pesto was one of my absolute favorites last summer. For some unknown reason I  forgot to post it until now. However sorrel is in some places in season again so here it is.

about 2 cups (about ½ liter) of young Cultivated Sorrel leaves
2 garlic cloves
a hand full of walnuts
fresh red chili to your own taste (I used about ½” = 1.3 cm)
½ cup (100 ml) grated parmesan
olive oil
a few sprigs of parsley (optional)
season with: salt and pepper

I picked about 2 cups of very young Cultivated Sorrel leaves. Rinse the leaves in cold water and drain while you prepare the other ingredients. Chop the walnuts and the chili a little. Grate the Parmesan roughly.
When the sorrel is dry, run them in the food processor (or use a mortar and pestle). Add chopped garlic and run the machine a bit before adding chili, walnuts,  (parsley) and parmesan. Drizzle some olive oil over. Blend the mixture carefully as it should have a crunchy texture. If necessary add some more olive oil. Season with salt and fresh pepper. Serve the pesto as an appetizer on crackers. I also think the sourness in this pesto works terrificly well with fish.

This pesto is also a great summer present, especially when you have a garden like mine where sorrel or lettuce grows much better than most flowers.
