Recommendation: bundle these ingredients into a coffee filter, tied at the top so that it makes a sachet of the spices so that it's easier to separate them from the liquid when you're ready to pour.
Let the ingredients cool together for 30+ minutes, before adding the whiskey. In a shaker, I added 1 liquid egg white into the spiked mulled spices, giving the cocktail a smooth, rich taste and feel. So, it's basically a protein packed, antioxidant rich blend that boosts immunity and aids digestion .. guilt free yet festive Saturdays have never been more delicious!
