Cumquat Marmalade

Cumquats belong to a citrus subspecies. The oval cumquat can be easily identified by the oval shape of the fruit and has a sweet, oily skin and can be eaten whole, crystallised, or used to make jams, conserves and liqueurs. Nurseries have often confused round cumquats with the calamondin which is more rounded and has more segments and a sweeter flesh and rind flavour.

Although resembling a cumquat, the calamondin is similar to a very small mandarin and has a loose, bright orange skin when ripe. Note that the photo on the right shows an unripe calamondin fruit.Both cumquats and calamondins can be made into a tasty marmalade.


  • 750g cumquats
  • 1.5L water

  1. Slice fruit thinly, putting seeds in a basin with half litre of water.
  2. Cover fruit with 1 litre water and soak overnight.
  3. Next day, boil fruit and liquid, also water from seeds, until liquid is reduced to about one half.
  4. Add sugar and lemon juice. Stir until sugar dissolves.
