It's the holidays, right? We still have time to sneak in a few indulgences? Good, just the excuse I need for these creamy garnet sweet potatoes splashed with smoky bourbon.

Funny thing is, if you looked in our liquor cabinet, you would find all sorts of wonderful things to drink—vermouth, marsala, madeira, rum, calvados, JD, Maker's Mark—yet nobody in our family actually drinks anything beyond an occasional glass of wine or beer. Or maybe a small glass of sherry or port.

All those high octane bottles are for use in cooking, including the bourbon. I love the taste of bourbon, with its slightly smoky edge. But I'm a lightweight when it comes to alcohol, so only use it for flavoring something wonderful, like chocolate bourbon cake, a New Orleans bread pudding, or these sweet potatoes.

Don't Skip the Bourbon

For those of you who avoid alcohol in cooking, I'm afraid this recipe is not for you.

Obviously you can easily make the mashed sweet potatoes without the bourbon; it will be great, just add some nutmeg and cinnamon to spice it up a bit.

I did experiment with reducing the alcohol content in this recipe by boiling the bourbon first to accelerate the evaporation, but while the alcohol was reduced, so was the taste of the bourbon. So if you want the wonderful note that the bourbon provides, you'll just have to add it as is.

The Best Sweet Potatoes to Use

Look for garnet sweet potatoes for this recipe. These sweet potatoes have a reddish-brown skin and bright orange flesh. They cook quickly, mash easily, and have a pleasantly sweet flavor.

How Long to Boil Sweet Potatoes

For these mashed sweet potatoes, peel the potatoes, cut them into large cubes, and then boil them until tender. This should take roughly 15 to 20 minutes.

What to Do With Leftover Mashed Sweet Potatoes

Leftover mashed sweet potatoes will keep for about 5 days in the fridge.

They can be reheated on their own for an easy weeknight side, or use them to top a shepherd's pie, fry them into thin potato pancakes, or mix them into a lightly boozy version of our sweet potato waffles.
