Cut one fresh lemon in half and squeeze out 2 ounces of juice using a citrus juicer or hand squeezer.

Pour 4 ounces of vodka into a small mixing bowl or pitcher, then add the freshly squeezed lemon juice and 2 ounces of water.

Start with 1/4 teaspoon of cayenne pepper, add it to the mixture, and taste a small sample to gauge the heat level.

Stir in 1 tablespoon of honey and whisk vigorously until the honey dissolves completely.

Use a bar spoon or regular spoon to stir the mixture for about 30 seconds until all ingredients are fully incorporated and the cayenne is evenly distributed.

Optional: Pour the mixture through a fine mesh strainer to remove any cayenne particles for a smoother texture.

Pour the strained mixture evenly into four 1.5-ounce shot glasses, filling each glass about three-quarters full.

Chill the filled shot glasses in the freezer for 10 to 15 minutes until ice-cold, or serve immediately at room temperature.
