Etrog (Esrog) Jelly

Recipe by RivkaD
READY IN: 2hrs
YIELD: 6 cups




  • GET RID OF BITTERNESS: Wash etrog and trim off the ends. Slice thinly, or chop. Put the slices and the seeds into a cheesecloth bag. Day 1: Cover with water and let stand at least 12 hours. Bring to a boil, and simmer uncovered for 20 minutes. Drain fruit. Cover with cold water & repeat on Day 2.
  • Day 3: Drain fruit, then cover with cold water & simmer uncovered 1 hour. Take out the bag of fruit and seeds. Let it cool down, then squeeze every drop into the pot and throw out the mush.
  • Mix pectin with 1/4 cup sugar. Add sugar, pectin & marmalade and simmer. To become jelly, there has to be the right concentration of sugar, so if you put in more water or less sugar it takes longer to boil down. It will probably reach 200º quickly, but then it takes up to an hour to get up to “jelly” temperature (220º–222º). After it gets to 215º stir constantly and DO NOT WALK AWAY – it burns easily. If it does burn, just dump the jelly into a clean bowl, wash out your pot, put the jelly back in and continue.
  • Put a saucer in the freezer to check for when your jelly is done. It should gel when you pour a little on your very cold saucer. If it still won’t set after getting to 220º, cook 15-20 minutes more! (You could also just quit & call it etrog syrup.) If you overshoot the “gel” point, you will end up with more of a candy than a jelly.
  • How to put in jars: Put your clean jars and lids in a pot, fill the pot and jars with cold water. Bring to a gentle boil for 10 minutes. Drain out a hot jar, fill with hot jelly leaving 1/4" "headspace," put on the hot lid tight. As it cools, the little button on the top that popped up when you first opened it will pop down again. This is what keeps out the bacteria that would spoil the jelly.
  • Keeps 3 years in pantry. After opening, keep in fridge 4-6 months.
