Naughty Sweet Potato Pie

This sweet potato pie earns its naughty name from the half-cup of orange liqueur (Grand Marnier or Cointreau) that goes into the custard. The alcohol mostly cooks off in the oven but leaves behind a bright orange-essence depth that plays against the warm cinnamon, ginger, and nutmeg. It’s the kind of small move that takes a familiar holiday pie somewhere unexpected.

Dealing with yam fibers is the unglamorous reality of homemade sweet potato pie. Even fully cooked yams have stringy connective tissue that wraps around mixer beaters. Stop and clean the beaters as needed; don’t try to power through. Strands left in the filling read as off-putting hairs in every slice.

Evaporated milk gives this pie its signature dense, creamy custard. Don’t substitute regular milk or even cream. Evaporated milk has been concentrated by removing about 60% of its water, which means you get rich body without thinning the filling.

Nutmeg leads here at a full teaspoon, more aggressive than most sweet potato pies. It’s intentional. The nutmeg balances the orange liqueur and keeps the spice from going one-note cinnamon.

Pro Tips

• Roast the sweet potatoes instead of boiling for deeper flavor. Boiled yams come out watery and dilute the custard.
• Cover the crust edges with foil after 30 minutes if they’re browning too quickly.
• Cool the pie completely (at least 2 hours, ideally overnight) before slicing. The custard needs time to set fully.

Variations

• Swap orange liqueur for bourbon or dark rum for a different spirit profile.
• Top with toasted pecans or a streusel crumble in the last 15 minutes of baking.
• Make it dairy-free by substituting full-fat coconut milk for the evaporated milk.
