Dark Muscovado & Whisky Marmalade Recipe
Introduction
This dark muscovado and whisky marmalade offers a rich twist on a classic preserve. Combining the bittersweet tang of Seville oranges with the deep molasses flavor of muscovado sugar and a warming hint of whisky, it’s perfect for adding a touch of elegance to your breakfast or afternoon tea.

Ingredients
- 1.3kg Seville oranges
- 2 lemons, juice only
- 2¼kg granulated or preserving sugar
- 450g dark muscovado sugar
- 150ml whisky
Instructions
- Step 1: Place the whole oranges and lemon juice in a large preserving pan and cover with 2 litres (4 pints) of water. If the water does not fully cover the fruit, use a smaller pan or weigh the oranges down with a heat-proof plate to keep them submerged. Bring to the boil, then cover and simmer gently for about 2 hours, or until the peel can be pierced easily with a fork.
- Step 2: Warm half of the granulated and muscovado sugars in a very low oven. Pour off the cooking water from the oranges into a jug, then tip the oranges into a bowl. Return the cooking liquid to the pan.
- Step 3: When the oranges are cool enough to handle, cut them in half and scoop out all the pips and pith, adding them to the reserved orange liquid in the pan. Bring this mixture to a boil for 6 minutes, then strain it through a sieve into a bowl, pressing the pulp with a wooden spoon to extract the pectin-rich liquid.
- Step 4: Pour half of the strained liquid back into a preserving pan. Cut the peel into chunky shreds with a sharp knife and add half of it to the liquid along with the warm granulated and muscovado sugars. Stir gently over low heat until the sugars dissolve completely.
- Step 5: Bring the mixture to the boil and boil rapidly for 15–25 minutes until it reaches the setting point. Stir in half the whisky, then remove from heat and skim off any scum from the surface. To help dissolve scum, add a small knob of butter and stir gently.
- Step 6: Let the marmalade stand in the pan for 20 minutes to cool slightly and allow the peel to settle. Then pot it into sterilised jars, seal, and label. Repeat all steps with the remaining fruit, sugars, and whisky for the second batch.
Tips & Variations
- Replace the whisky with Grand Marnier, Drambuie, or Cointreau for a different flavor profile.
- Use 2.6kg (6lb) granulated sugar instead of muscovado sugar and add 2 tablespoons black treacle (1 tablespoon per batch) to deepen the color and flavor of the marmalade.
Storage
Store the sealed jars of marmalade in a cool, dark place for up to 1 year. Once opened, keep refrigerated and use within a few weeks. Reheat gently before serving if desired to soften the marmalade.

FAQs
Why use Seville oranges for marmalade?
Seville oranges have a naturally bitter flavor and high pectin content, which helps the marmalade to set well and gives the preserve its characteristic tart taste.
Can I substitute the whisky with another type of alcohol?
Yes, spirits like Grand Marnier, Drambuie, or Cointreau work well as substitutes, adding unique flavors while maintaining the marmalade’s warmth and depth.

Ingredients
Main Ingredients
- 1.3 kg Seville oranges
- 2 lemons, juice only
- 2¼ kg granulated or preserving sugar
- 450 g dark muscovado sugar
- 150 ml whisky
Instructions
- Prepare and Simmer Fruit: Place the whole Seville oranges and freshly squeezed lemon juice into a large preserving pan and cover with 2 liters (4 pints) of water. If this volume doesn’t fully cover the fruit, use a smaller pan or weigh down the oranges with a heat-proof plate. Bring the mix to a boil, then cover and simmer gently for about 2 hours until the peel becomes easily pierced with a fork.
- Warm Sugar & Save Cooking Liquid: While the fruit cooks, warm half of both the granulated sugar and dark muscovado sugar in a very low oven to dissolve more easily later. Once the fruit is tender, carefully pour off the cooking water into a jug and transfer the oranges to a bowl.
- Cool and Prepare Fruit: Return the cooking liquid to the pan and let the oranges cool until they can be handled. Cut each orange in half, scoop out seeds and pith, and add these to the reserved cooking liquid in the pan.
- Extract Pectin from Seeds & Pith: Bring this mixture to a boil for 6 minutes, then sieve the liquid through a fine sieve, pressing the pulp with a wooden spoon to extract high-pectin juice which helps the marmalade set well. Discard solid remains afterwards.
- Cook First Batch: Pour half of the strained liquid into the preserving pan. Using a sharp knife, cut the peel into chunky shreds and add half of the shredded peel along with half of the warmed granulated and muscovado sugars to the pan. Stir over low heat until sugar is fully dissolved, then bring to a vigorous boil and cook for 15-25 minutes, until the marmalade reaches setting point.
- Add Whisky and Finish: Stir in half the whisky and remove the pan from heat. Skim off any scum from the surface; to dissolve excess scum, add a small knob of butter and gently stir. Let the marmalade stand for 20 minutes to cool slightly and allow the peel to settle.
- Jar and Repeat: Pot the marmalade into sterilised jars, seal, and label. Repeat the entire cooking process with the remaining peel, sugars, liquid, and whisky for the second batch.
Notes
- You can substitute whisky with Grand Marnier, Drambuie, or Cointreau for a different flavor profile.
- For a darker marmalade without muscovado sugar, replace it with 2.6 kg granulated sugar and add 2 tablespoons black treacle (1 tablespoon per batch) to deepen color and richness.
- Using a low oven to warm the sugar helps it dissolve more easily during cooking, preventing graininess.
- Scum on the surface is normal; the butter trick helps clarify the marmalade for better texture and appearance.
- Sterilising jars properly ensures long shelf-life and food safety of your marmalade.
