  • 12 lemons organic and unwaxed


  • Pre-heat oven to 80C / 60C fan and line a couple of large baking trays with baking parchment.
  • Slice the lemons thinly using a very sharp knife. Discard any slices that are slightly ripped as these have a tendency to burn.
  • Place the lemon slices on the baking trays.
  • Bake in the oven for 2 hours.
  • Turn each lemon slice over.
  • Bake for a further 2 hours (*see notes)
  • Remove lemon slices from oven which should be golden and crisp to touch.
  • Leave to cool before processing in the grinder.
  • Grind the lemon slices in batches. Place a small amount of the dried lemon slices in the spice grinder (about 10). Use the guide on your grinder to confirm the maximum amount you can fill it.
  • Grind the slices for about a minute using the instructions on your grinder. The lemon slices will turn into a golden powder. You may need to give the powder a second grind to get a really fine powder.
  • Store the lemon powder in an airtight glass jar in a cool dark place for up to a year.


  • Cut the lemons as uniformly as possible.
  • You can use a mandoline set at 4mm width.
  • Don’t remove the seeds from the lemon slices before you put them in the oven but pop them out before you grind them.
  • *Check your lemons frequently in the oven. The lemon slices need about 4 hours in a very low oven. However, if you are cutting your lemon slices by hand then there may be some variation on how long they take. Check their progress regularly. Some slices may be done around 3½ hours depending on their thickness.
  • The lemon slices are ready when they are crisp and not damp to the touch, translucent and golden yellow.
  • Run the lemon slices through the spice grinder twice. After the initial grind, scrape the powder out of the grinder, whisk it together in a small bowl then pour back in the grinder for a second go. It should be powdery fine when finished.
  • Use the lemon powder in cakes, seasonings, tea or homemade beauty products.
