In a cocktail shaker filled with ice, combine equal parts Skrewball whiskey and fruit liqueur.
Shake 10-15 seconds until icy cold.
Strain the shot mixture into a shot glass. Enjoy immediately.
Notes
Choose a grape liqueur for a grape jelly flavor or raspberry to simulate raspberry jam flavor.
If you want to make a jello shot version, try mixing Skrewball whiskey with grape jello.
If you need to substitute the screwball peanut butter whiskey, try Frangelico (which is hazelnut liqueur) instead. Some recipes also use Frangelico combined with Irish cream liqueur (such as Bailey's).
