The Method for Pink Grapefruit Marmalade

Step 1: Prepare the Grapefruits

Start by thoroughly washing the grapefruits to remove any dirt or residues. If they are unsprayed, you can enjoy the peel without worries. Cut each grapefruit in half and juice them, reserving both the juice and the peels. Make sure to remove any seeds from the juice as you go.

Step 2: Slice the Peels

Take the reserved grapefruit peels and slice them into thin strips. The thinner the slices, the more tender they will be after cooking. This is where the magic happens—those peels will infuse the marmalade with a wonderful bitterness that complements the sweetness.

Step 3: Cook the Peels

In a large pot, combine the sliced peels and the 5 cups of water. Bring the mixture to a boil, then reduce the heat and let it simmer for about 30 minutes. This softens the peels and helps release their flavor. After simmering, drain the peels but reserve the cooking liquid.

Step 4: Combine Ingredients

Return the softened peels to the pot and add the reserved grapefruit juice, the cooking liquid, sugar, and lemon juice. Stir well to combine all the ingredients.

Step 5: Cook the Marmalade

Bring the mixture to a boil over medium heat, stirring frequently to dissolve the sugar. Once the mixture reaches a rolling boil, allow it to cook for about 30-45 minutes. If using a candy thermometer, aim for a temperature of 220°F (104°C), which indicates the marmalade is ready to set.

Step 6: Test for Doneness

To check if the marmalade has reached the desired consistency, place a spoonful on a plate and let it cool for a minute. Run your finger through it; if it holds its shape and doesn’t run back together, it’s done!

Step 7: Jar the Marmalade

Once the marmalade is ready, carefully pour it into sterilized glass jars. Leave about 1/4 inch of headspace at the top. Seal the jars with lids while the marmalade is still hot, and let them cool completely.

Better Choices & Swaps

For a lower sugar option, consider using a sugar substitute suitable for canning.
You can mix in other citrus fruits like oranges or lemons for a unique flavor twist.
Swap out the lemon juice for lime juice for a different citrus profile.

Steer Clear of These

Do not use conventional grapefruits that may have pesticides, as they can affect the flavor and quality of the marmalade.
Steer clear of using artificial sweeteners that are not suitable for canning.
Avoid using overripe grapefruits; they may not set properly.

Best Ways to Store

Store your Pink Grapefruit Marmalade in a cool, dark place. Once opened, keep the jar in the refrigerator, where it will last for several weeks. Unopened jars can be stored at room temperature for up to a year. Always check for signs of spoilage before consuming.
