Step one

Combine 13 grams of dried Butterfly Pea Flowers with up to 3 liters of water in a saucepan.

Step two

Cover and heat for 15 minutes on a medium/low setting.

Step three

Remove the cover.

Step four

Press the flowers against the edge of the pot with the back of a stirring spoon to release additional pigment. (You can do this as much as you'd like until the flowers turn white.)

Step five

Remove the flowers with the stirring spoon, or strain the dye.

Step six

You can make this recipe in batches. Depending on the amount of pigment in the flowers, you might be able to get a larger quantity of dye. Try varying the number of flowers or water in the recipe to get a weaker or more concentrated solution. You can use the dye straight away. You could also store it in a clean jar or glass for up to 3 days at room temperature. You can keep this in the fridge if you want to keep it longer. You can even freeze the dye once it is at room temperature. You substitute this dye for water in a biomaterial recipe.
