To take the zest from the lemons...
Buy organic lemons (not lemons that are untreated after harvest but may have been treated many times before!).
Wash them and remove the peel with a vegetable peeler, taking care to put the hand holding the lemon in a thick glove (in case it slips… and I can assure you it slips now and then). The peeler takes off the peel and not the white part, which turns bitter when cooked.
Lay several strips of peel on top of one another and cut as finely as possible with fine scissors.
