Cut the lemon into 4 wedges and arrange them with the other ingredients in a microwave safe container with a lid on.
Place the lemon mix in the microwave on a medium-high heat for 2 minutes. Stir the mixture and repeat this at least 5 times depending on the power of your microwave.
When finished, transfer the preserved lemon to an air-tight container and refrigerate for 24 hours before use.
Notes
If the organic lemons are unavailable, blanch them for 1 minute to remove pesticides, chemicals or wax that may be on them.
