Walnut-Infused Whiskey
To create walnut-infused whiskey:
500ml Bushmills Original Irish Whiskey
100g walnuts
1. Add ingredients to a plastic or metal bowl covered with cling film and leave overnight.
2. Strain walnuts through a sieve or cloth into a clean glass or plastic bottle.
Alternatively, instead of walnut-infused whiskey, you can use Hazelnut liqueur.
