BeginnersCalcium LactateLM PectinXylitol

This low sugar alternative to a traditional jam lets the uniquely tart and slight bitterness of grapefruit to shine through. We added xylitol as a low-cal blood sugar friendly alternative to sugar for a lightly sweetened finish.

Ingredients

  • 300g (1¼ cup) Grapefruit Juice
  • 50g (4 tbsp) Grapefruit Zest
  • 65g (¼ cup + 1 tbsp + 1 tsp) Xylitol
  • 100g (¼ cup + 1 tsp) Water
  • 20g (2 ½ Tbsp) LM Pectin
  • 4g (1 tsp) Calcium Lactate

Equipment

  • Vegetable Peeler
  • Microplane
  • Small Heavy Bottom Pot
  • Sanitized Mason Jars

Timing

Active Time: 20 Minutes

Total Time: 2 Hours

Yield

1 Pint

  • Prepare Grapefruit

    Peel zest to your liking, either with a vegetable peeler then finely sliced or if you prefer a smoother marmalade microplane the zest.

    Place a large heavy bottom pot over medium heat. Add the grapefruit juice, water, and zest to the pan and allow it to simmer.

    Cook on low until the zest is cooked to your liking.

  • Add Dry Ingredients, Boil

    Dry blend the xylitol, LM pectin, and calcium lactate.

    Whisk the grapefruit mixture and sprinkle in the xylitol, LM pectin, and calcium lactate.

    Bring this mixture to a gentle boil and cook for 2 minutes.

    Pour this mixture into the sanitized jars and seal. Allow the jars to cool until they seal themselves.

    Store for up to a year if kept sealed or a month in the refrigerator.

I love your recipes. Can you please tell me what the calcium lactate in the recipe does? I might recommend that in your recipe write ups, you mention what any modernist ingredients do for the recipe so we can learn.

If I want to make this recipe with strawberries instead, do I replace the grapefruit juice and zest with an equal amount of strawberries (350 grams)?
Also, can I use a different sweetener other than Xylitol? Maybe Stevia?

yes, for the most part all the fruits are interchangeable and also yes the sugars can swapped as long traditional sugar isn’t used.
