There’s something undeniably special about homemade marmalade, especially when it’s vibrant and zesty pink grapefruit marmalade. This recipe transforms the tartness of pink grapefruits into a sweet, spreadable delight that can elevate your breakfast toast or liven up your desserts. Imagine waking up to the bright, citrusy aroma wafting through your kitchen, as the sun rises and the day begins. With just a few simple ingredients, you can create a jar of sunshine that will last for months.
Why This Pink Grapefruit Marmalade Stands Out

What makes this pink grapefruit marmalade truly exceptional is its unique balance of flavors. The natural bitterness of the grapefruit peels harmonizes beautifully with the sweetness of sugar and the acidity of lemon juice. This marmalade is not just a condiment; it’s an experience. The pretty pink hue adds a pop of color to any breakfast table, while the tangy-sweet taste can transform plain yogurt or oatmeal into a gourmet dish. Plus, it’s made from fresh, organic ingredients, ensuring that every spoonful is as wholesome as it is delicious.

- Juice of 1 lemon
What You’ll Need (Gear)
- Large pot: For cooking the grapefruit and water mixture.

From Start to Finish: Pink Grapefruit Marmalade

Step 1: Prepare the Grapefruits
Begin by thoroughly washing your pink grapefruits to remove any dirt or residues. Cut them in half and juice them, ensuring to reserve the peels. You can use a juicer for this, but hand-squeezing works just as well if you don’t have one.
Step 2: Slice the Peels
Using a sharp knife, carefully remove the white pith from the grapefruit peels. This part can be quite bitter, and we want to keep the flavors balanced. Once the pith is removed, slice the peels into thin strips.
Step 3: Cook the Peels
In a large pot, combine the sliced peels with enough water to cover them. Bring this to a boil and then reduce the heat, simmering for about 30 minutes. This process helps to soften the peels and reduce bitterness. Drain and set aside.
Step 4: Combine Ingredients
In the same pot, add the cooked peels, grapefruit juice, lemon juice, and 5 cups of water. Stir well to combine. Gradually add in the sugar, mixing until it’s fully dissolved.
Step 5: Cook the Marmalade
Bring the mixture to a rolling boil over medium-high heat. Reduce heat slightly and let it simmer, stirring frequently. Cook until the marmalade reaches a temperature of 220°F (104°C) on a candy thermometer, which usually takes around 30-40 minutes.
Step 6: Test for Doneness
To check if your marmalade is set, place a small spoonful on a chilled plate and let it sit for a minute. Run your finger through it; if it holds its shape and does not run back together, it’s ready to be jarred.
Step 7: Jar the Marmalade
Carefully ladle the hot marmalade into sterilized jars, leaving about a quarter-inch of headspace at the top. Wipe the rims of the jars with a clean cloth to ensure a good seal, then place the lids on and screw them tightly.
Step 8: Process the Jars (Optional)
If you want to store your marmalade for an extended period, process the jars in a boiling water bath for 10 minutes. This step helps to seal the jars and ensures your pink grapefruit marmalade stays fresh longer.
