Use a fresh organic cucumber. Slice the cucumber. Add 1 teaspoon of salt and 2 tablespoons of lemon. If available, you can add some dill. Mix all ingredients and bring under pressure in a pickle press, if you have one. If you don't have a pickle press, you can use a bowl, that you fill with the ingredients and cover with a plate and a stone on top of it. Let it sit like this for a day. This makes a great and very tasty pickle, rich in enzymes. You can keep it in the fridge for a few days. The salt and lemon act as preservatives.
