If you haven’t tried (or heard of) butterfly pea flowers, they are small plant that has an incredibly blue flower. It has been used as tea for centuries in south east Asian countries. It’s a caffeine free herbal tea.

One of the really cool things about this tea is when steeped it comes out a really dark blue colour, but when you add an acid like lemon juice, it changes the colour from blue to a bright purple. It’s really cool!

Now I haven’t seen this tea in stores around my area in southern Ontario, but I did find some while I was in Nova Scotia recently. It was at a specialty store that had lots of products from Asia. So if you have an Asian grocer around – you might be able to find it there.

So this sugar free iced tea lemonade is really delicious! One note I will say, is that if you don’t have simple syrup, then you can stir in 1-2 teaspoons of sugar substitute (icing/powdered is best that way it won’t crystalize)

I used Skinny Syrup Dragonfruit Acai, but I also have a delicious Skinny “simple syrup” that would also work great for this drink.
