Instructions:
240 mL vodka, 240 mL gin, 240 mL silver tequila,3 clean jars,15 - 24 dried butterfly pea / blue pea flowers
Place each of the spirits in the 3 clean jars. Add 5 - 8 flowers into each jar, close tightly and lightly shake the contents to mix.
Label and leave the jars in a cool place to infuse overnight.
When the spirits turn dark purple or blue in color, strain the alcohol into bottles.
For the vodka and tequila
If the liquor is purple, and you prefer the alcohol to be blue, using the flat toothpick or a small spoon, transfer a pinch of baking soda into each of the bottles. Swirl to mix and check the color.
¼ tsp baking soda + flat toothpick
Repeat with very small amounts of baking soda, until it turns blue (stop adding as soon as you notice the desired blue color).
Store all infused liquors in a cool place (or fridge or freezer), until needed.
