Whisky apple butter sauce is a rich and flavorful condiment that pairs perfectly with a variety of dishes. Made with a combination of sweet apples, butter, brown sugar, and a splash of whisky, this sauce has a deep caramelized flavor with a hint of smokiness. It is great for drizzling over pancakes, waffles, or ice cream, or as a glaze for roasted meats. The sauce can be made ahead of time and stored in the refrigerator for up to a week.
