Grapefruit Marmalade Recipe FAQs
How do I know if my grapefruits are ripe enough?
Absolutely! Choose grapefruits that feel heavy for their size and have smooth skin. They should be bright in color without dark spots or blemishes. The riper the grapefruit, the sweeter and more flavorful your marmalade will be.

Once sealed, you can store unopened jars of your grapefruit marmalade in a cool, dark cupboard for up to 1 year. After opening, keep it in the refrigerator where it will last for about 3 weeks. Ensure the lid is tightly sealed to keep it fresh and delicious!
Can I freeze grapefruit marmalade?
Very much! To freeze, transfer the marmalade into freezer-safe containers, leaving enough space at the top for expansion (about 1/2 inch). It can be stored in the freezer for up to 1 year. When ready to use, simply thaw in the fridge overnight or gently reheat on the stovetop.
What if my marmalade doesn’t set properly?
No worries! If your grapefruit marmalade isn’t setting, it may need more cooking time. Return it to the heat and boil again for 5-10 minutes. You can also do the plate test: spoon a little onto a cold plate and see if it gels after cooling for a minute. If it doesn’t, just keep cooking until it reaches the desired consistency.
Is grapefruit marmalade safe for pets?
While a small amount might be fine, it’s best to avoid sharing marmalade with pets, especially dogs. The sugar content and citrus can upset their stomachs. Always check with your vet for guidance on what’s safe for your furry friends.
What should I do if I want to make my marmalade less sweet?
Absolutely! You can reduce the sugar amount incrementally to find the balance that suits your taste. However, remember that sugar not only sweetens but also helps in preservation. A good starting point is to cut the sugar by one cup—just be sure to keep an eye on the set during cooking.
