Instructions

  1. Scrub the fruit, and dry. Using a zester, remove the peel (from all three), being careful not to get any pith. If you do not have a zester, use a vegetable peeler, being careful to remove *only* the zest. Then, using a sharp knife, or shears, cut the peel into fine strips. I have also grated the peel, but it doesn't look as pretty.
  2. Place the zest in a small saucepan with the water and the baking soda, and bring to a boil. Reduce the heat and simmer for 20 minutes.
  3. In the meantime, slice the top and bottom of each fruit, so that it sits flat on your cutting board. Using a sharp knife and following the contour of the fruit, cut away all the pith, leaving only the pulp.
  4. While holding the fruit over a bowl (to catch all the juices), use the knife to cut out the flesh, leaving the membrane. Remember, it's the pith and the membrane that make marmalade bitter.
  5. Add the pulp and juice to the simmering zest (do not drain the zest). Simmer, covered, for 10 minutes.
  6. Measure 3 cups of the mixture and mix it together with the sugar in a large pot.
  7. Bring to a rapid boil. Stir and boil hard for 1 minute. Immediately remove the pot from the heat.
  8. Add the pouch of pectin, and stir for 10 minutes. This will cool the mixture slightly and prevent the zest from floating.
  9. Pour into sterilized jars and seal.
