Start by collecting all your ingredients and equipment. Fresh elderflowers are crucial, so pick them on a dry day to avoid excess moisture.

In a saucepan, combine the water and sugar. Heat gently, stirring until the sugar completely dissolves, creating a simple syrup.

Remove the saucepan from heat. Stir in the zest and juice of the lemon.

In a large glass jar, place the elderflower heads. Pour the warm syrup over the flowers, ensuring they are fully submerged.

Pour the vodka into the jar, covering the elderflowers and syrup.

Seal the jar tightly and give it a gentle shake. Store it in a cool, dark place for about 5 days, shaking it daily.

After 5 days, strain the liquid through a fine mesh strainer or cheesecloth into a clean container.

Using a funnel, pour the finished liquor into clean glass bottles. Seal them tightly and store in the refrigerator.
