There is no doubt that leek juice is an acquired taste so do not add too much the first time you try this! Leeks are very rich in sulphur, and therefore great for detoxing, and hugely strong flavour (they will make your eyes water too)! Be sure to juice them with something sweet to counteract the strong flavour. Coriander is rich in vitamins and minerals, and adds a wonderful earthy flavour to this juice.
1/4 small leek (including the upper green leaves)
1 large tomato
1 small handful coriander (use fresh parsley if you prefer the flavour, as I do)
Juice all the ingredients and stir well before serving.
