Ingredients

Directions

Prepare the fruit

  1. Peel the oranges and lemons.

  2. Cut up the fruit and squeeze them into a crock pot.

  3. Use a garlic press, potato ricer, juicer, or fruit squeezer to extract juice.

  4. Put the remaining fruit pulp into the crock pot as well.

Cook the mixture

  1. Add the raisins, honey, and spices. Stir.

  2. Do not add whiskey yet.

  3. Start the crock pot and let the mixture cook for about 2–4 hours. Stir occasionally.

  4. The mixture is complete when the fruit pulp is cooked down.

Strain and serve

  1. Strain the mixture into a pitcher.

  2. Mash down the fruit in the strainer to get all the liquid.

  3. Add the whiskey to the pitcher and stir. If you cook the whiskey, even for a short time, the alcohol will start to evaporate.

  4. Taste, and add more whiskey to your liking.

  5. Serve hot in shot glasses, espresso cups, or coffee mugs.

  6. After the first round, each serving can be reheated in the microwave.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oranges
Provide juice and citrus aroma that give the drink its bright, fresh flavour.
Lemons
Add acidity that balances the sweetness of the honey and raisins.
Raisins
Add body and natural sweetness as they soften and release their sugars during cooking.
Honey
Adds sweetness and a smooth, rounded body to the spiced citrus base.
Whiskey
Provides the alcohol and warming, oaky flavour, added after cooking so it is not evaporated.

The step that matters

Add the whiskey after cooking. Alcohol evaporates when heated, so even brief cooking drives off the whiskey and weakens the drink. Stirring it in off the heat keeps its strength and flavour.
