When Life Hands You Lemons…

… halve them, remove as many seeds as you can without being overly paranoid about it, chop them into bits your food processor can handle, and place them in the food processor with salt and sumac. The ratio is about 1 tbsp each for every batch of six lemons. Process until you get a sort of chunky paste. Pack in jars and drizzle some olive oil on top. Leave to ferment for a week. What you get is a wonderful pickled lemon paste, which works beautifully as a sandwich filler, salad dressing, an original and tasty avocado topping, a nice complement to grains and beans,  and, with the addition of basil leaves, a very lemony and special pesto.
