Homemade Lemon Lime Marmalade
Prep time
Cook time
Total time
Serves: 4-5 half pints
  • 1 pound lemons, thoroughly washed
  • 1 pound limes, thoroughly washed
  • 6 cups water
  • 7 cups white granulated sugar
  1. Cut off the very ends of the lemons and limes. Very thinly slice the lemons and limes. The easiest way to do this - and to do it quickly - is to use a mandoline slicer. Quarter the slices. Remove any seeds.
  2. Add the citrus to a medium-sized pot with the water and bring to a boil. Reduce the heat to a steady simmer and simmer for one our until the citrus is very soft. Give it an occasional stir.
  3. Add the sugar and return to a full boil. Reduce to a steady simmer and simmer for another 20-30 minutes or until a candy thermometer reaches 220-225 degrees F. (Using a candy thermometer will ensure proper results and makes the job easier, plus they're relatively inexpensive. I highly recommend buying a candy thermometer.)
  4. If you'd rather not get a candy thermometer you can use the "plate test." Simply place a plate in the freezer for a few minutes and then place a dab of marmalade on the cold plate. Tilt the plate to see if the marmalade is set. If it's too runny, it's not ready - continue simmering. If it congeals into a soft gel and only moves just a little, it's ready.
  5. Let the marmalade sit for 2-3 minutes, then skim the foam off the top of the marmalade and discard. Letting it sit will evenly distribute the citrus pieces so they don't float to the top when you place the mixture in your jars.
  6. Pour the marmalade into hot, sterilized jars leaving ¼ inch headspace from the top. To be extra safe, process the jars in a boiling water bath for 5 minutes. Keep the marmalade stored in a cool, dark place. It will keep for at least one year.
*A note about the rinds. You can use the lime rind whole but the white pith of the lemon is very bitter. You can use it as well, but just a heads up. If you prefer it less bitter, remove the white pith of the lemon and only use the outer yellow part. For the demo pictures below I have left the white pith intact.

*Also, citrus is sprayed and waxed and since we're using the rinds I recommend using organic lemons and limes.
