Sweet Potato Sour Thanksgiving Cocktail - on a blue plate, topped with toasted marshmallows
Sweet Potato Sour Thanksgiving Cocktail

When I started drinking bourbon, I loved adding a splash to my Aunt Vernie’s sweet potato casserole, but now I forgo the dish altogether a create a decadent and delicious sweet potato cocktail. The best part is that I just save some of the syrup from canned sweet potato and use that to make the cocktail. Add in whiskey, lemon juice, and a generous helping of toasted marshmallows and you’ve got a great Thanksgiving cocktail on your hands.

What’s in a Whiskey Sour?

A whiskey sour is an easy cocktail consisting of whiskey, citrus (usually lemon), and a sweet element. An easy ratio to remember is 2:1:1 – 2 parts spirit: 1 part sweet: 1 part sour, and that ratio works for sours from margaritas to daiquiris to whiskey sours.

Many people associate whiskey sours with summer, but seasonal sours are some of my favorite variations. In this case, I’m using flavors from Thanksgiving – the sweet potato – as the sweet element in the cocktail.

Fall Flavors in this Sweet Potato Cocktail

It’s possible to make sweet potato casserole without the marshmallow topping, but in a cocktail version, they are required. Not only do they sweeten the cocktail, but they also make it look gorgeous and textured with piles of tiny toasted marshmallows.

This sweet potato cocktail includes a dash of St Elizabeth’s Allspice Dram to add clove, cinnamon, and baking spice flavors to the drink. If you don’t have allspice dram, add a dash of spiced or aged rum to the cocktail.

For the whiskey, I chose bourbon because I put bourbon in my sweet potatoes and in my Thanksgiving cocktails. I use a mid proof bourbon – Elijah Craig Small Batch or Jim Beam Black – to build up the baking spice notes and keep the cocktail from being overly sweet.

For garnish I added the toasted marshmallows and a skewer with a sweet potato wedge on it. Dusting the top with fresh grated nutmeg is another excellent garnish idea. If you would rather not pile the Thanksgiving cocktail high with marshmallows, a single large marshmallow, toasted and dusted with nutmeg is a perfect alternative.

As a whiskey sour, this cocktail is fast and easy. It takes more time to toast the marshmallows that it does to mix.

Add your whiskey, lemon juice, sweet potato syrup and allspice dram to the shaker and fill with ice. Shake for 10-12 seconds and strain into chilled coupe glass.

Sweet Potato Cocktail: Aunt Vernie’s Sweet Potato Sour

I’ll admit sweet potato casserole often tastes more like a dessert than a side at Thanksgiving, but I couldn’t resist using the syrup from canned sweet potatoes to add some fall vibes to a fun Thanksgiving cocktail. Topping this sweet potato cocktail with torched marshmallows may be a bit over the top, but I’d imagine that’s what Aunt Vernie would do. I use allspice dram for that tropical hit of allspice, clove, and pepper flavors, but a spiced rum is a fine substitute.
