I found this recipe on liquor.com.

bourbon, lime juice, ginger beer⁣

It’s #derbyday! 🐎 Since I already featured a mint julep in the project, I saved a Kentucky Mule for today.⁣

Like I’ve said before, if you add ginger beer and lime to ANYTHING it is technically a mule. Before today, I had tried a Moscow Mule and a Mexican Mule, so this is my third mule. I can say that my favorite so far is Mexican (tequila, lime, and ginger beer).⁣

I had a mint julep earlier today while watching the Kentucky Derby, so I can compare a mint julep to a Kentucky mule, almost back to back. Mint julep is the better drink for me. Bourbon and ginger beer are kind of weird together. Not loving this. But it’s pretty. ⁣😆
