Add the petals and the water to a small saucepan over high heat.

As soon as the water starts to simmer, turn it down to low heat. Cover with a lid.

Allow to simmer for 30 minutes or until the petals lose all color (if using pink or red petals).

Let sit for 20 to 30 minutes to cool.

Strain through a fine-mesh sieve, to remove all the petals and small pieces.

Put in a jar and save in the refrigerator for up to 30 days.
