It’s a challenge making fun and exciting birthday cakes for my son using natural food colouring, but somehow it always works out great. This year he was really into angry birds, and I can definitely do red and yellow thanks to paprika and turmeric! The red frosting was dyed with a commercial natural food colouring from the UK, but the yellow frosting I tint with my own ground turmeric. I love the way these turned out and they were a big hit with the boys.
PS: I recently found out the trick to making blueberry frosting blue, not purple, and also found out it doesn’t taste like blueberry (a good thing) – I will do a blue post once I have perfected the colour!
