Begin by lightly crushing the fennel seeds to release their volatile oils. This can be done using a mortar and pestle or the back of a spoon. The goal is to crack them open slightly, not to grind them into a powder.

Bring a cup of water to a boil. You can do this in a small saucepan or a kettle, depending on your preference.

Once the water is boiling, add the crushed fennel seeds. Reduce the heat and let it simmer for 5 to 10 minutes. The longer you steep, the more pronounced the flavor.

After steeping, strain the tea into your favorite mug. Add honey or your preferred sweetener if you desire a bit of sweetness. A slice of lemon can also be added for an extra layer of flavor.
