Hot Rum – Dark Rum & Lemon Hot Toddy

The Hot Rum recipe is a straightforward hot toddy built around dark rum, fresh lemon, sugar, hot water, and cinnamon. Dark rum gives it depth and molasses character, while lemon keeps the drink bright and sugar smooths the edges. A cinnamon stick adds aroma without complicating a drink designed for easy, slow sipping.

A Rum Take on the Hot Toddy

Hot toddies have been made in various forms for centuries, typically combining a spirit with hot water, sugar, and sometimes citrus or spice. Whiskey versions became especially familiar, but rum works naturally in the same format. Its caramel and molasses notes pair well with lemon and warming spices, making rum toddies a natural cold-weather variation.

What You'll Need

Ingredients

• Dark Rum: Provides the drink's rich molasses, caramel, and barrel notes.
• Lemon Juice: Adds acidity that keeps the rum and sugar balanced.
• Sugar: Softens the citrus and rounds out the spirit.
• Hot Water: Dilutes the drink to a comfortable, sippable strength.
• Cinnamon Stick: Adds gentle spice and aroma as the drink rests.

Useful substitutions: Aged rum can replace Dark Rum for a slightly lighter profile. Honey can replace Sugar for a floral variation, though it will change the flavor and texture.

Equipment

• Heatproof Mug
• Spoon
• Jigger
• Measuring spoon
• Kettle or other source of hot water

Simple Ingredients, Clear Roles

This drink works because every ingredient has a specific job. The rum provides depth, lemon supplies contrast, sugar controls the tartness, and hot water opens the flavors without burying them. The Cinnamon Stick adds aroma gradually, so the spice stays in the background rather than dominating the drink.

Substitutions & Variations

• Aged rum: Swap Dark Rum for aged rum for a cleaner oak and vanilla profile.
• Spiced rum: Use spiced rum when you want more pronounced baking-spice notes.
• Honey: Replace Sugar with honey for a rounder, more aromatic sweetness.
• Demerara sugar: Use it in place of white Sugar for deeper caramel notes.
• Extra citrus aroma: Add a lemon peel alongside the Cinnamon Stick.

Helpful Tips

• Preheat the Mug with hot water, then empty it before building the drink.
• Dissolve the Sugar first so it does not settle at the bottom.
• Use fresh Lemon Juice for cleaner acidity.
• Add the Cinnamon Stick at the end rather than stirring in ground cinnamon.
• Taste after adding the Hot Water before making any sweetness adjustments.
• For a small batch, combine everything except the rum in a heatproof pitcher, then add Dark Rum shortly before serving.
