Introduction

This vibrant citrus marmalade blends grapefruit, lemons, and limes into a sweet, tangy preserve perfect for breakfast or baking. With simple ingredients and a careful cooking process, you can enjoy homemade marmalade bursting with fresh, zesty flavor.

A clear glass jar filled with shiny, dark orange-red jam sits on a brown plate. Next to the jar are three thick slices of bread stacked on top of each other; the top slice is spread with the same jam and a light yellow layer of butter beneath it. A silver spoon with jam rests leaning inside the jar, and a small butter knife with jam on its tip lies beside the plate. The background is blurred jars filled with more orange jam, all set on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 kg unwaxed citrus fruit (a mixture of grapefruit, lemons, and limes)
2.25 kg granulated sugar
Water (as needed, about 2½ litres initially)

Instructions

Step 1: Chill a saucer in the freezer to test the marmalade setting later. Wash the citrus fruits and remove the stalk ends.
Step 2: Place the whole citrus fruits in a large saucepan with 2½ litres of cold water. Bring to a boil, then cover and simmer for 2 hours 30 minutes, or until the skins are easily pierced with a small knife.
Step 3: Use a slotted spoon to remove the fruits from the liquid and let them cool for 10–15 minutes. Measure out 1.5 litres of the cooking liquid and return it to the pan, topping up with water if needed.
Step 4: Halve the cooled fruits, remove all pips and set aside. Slice the peel and flesh into thin strips about 0.2 cm thick, or to your liking. Return all peel, flesh, and juice back to the pan with the cooking liquid.
Step 5: Place the pips in a small piece of muslin cloth and tie securely with string. Add the muslin bag to the pan; this will aid the setting process.
Step 6: Stir in the sugar and bring the mixture to a boil. Boil rapidly for 45–50 minutes, stirring often. The marmalade should reach 105°C or set when tested.
Step 7: To test, drop a little marmalade onto the chilled saucer and cool for 1 minute. Press gently with a finger; if it wrinkles, it’s ready. If not, boil a little longer and test again.
Step 8: Remove the muslin bag with a slotted spoon. Let the marmalade cool in the pan for 10–15 minutes, then stir gently in one direction to remove air bubbles.
Step 9: Pour the marmalade into sterilised jars, seal with lids, and store.

Tips & Variations

Use a mixture of citrus fruits to balance sweetness and acidity for a complex flavor.
Adjust the peel thickness to change the texture; thinner strips create a smoother marmalade.
For a less bitter marmalade, soak peeled fruit in cold water for an hour before cooking.

Storage

Store sealed jars in a cool, dark place for up to one year. Once opened, keep refrigerated and consume within a few weeks. To reheat, warm gently in a saucepan or microwave, stirring occasionally.

How to Serve

A clear glass jar filled with orange-red jam with visible fruit pieces sits on a brown plate, next to three thick slices of crusty bread layered with melted butter and topped with a generous spoonful of the jam. A silver spoon rests inside the jar with some jam dripped onto the plate, while a knife with jam on its tip lies beside the plate on a dark cloth. In the blurred background, multiple glass jars of the jam are displayed against a dark backdrop. The whole scene is set on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use other citrus fruits instead of grapefruit, lemons, and limes?

Yes, you can experiment with oranges, tangerines, or even bitter Seville oranges. Mixing different citrus fruits alters the marmalade’s sweetness and bitterness, so adjust sugar accordingly.

Why is the muslin bag of pips important?

The pips contain natural pectin, which helps the marmalade set without needing additional additives. Removing the bag after cooking prevents unwanted seeds from ending up in your marmalade.
