My niece, S, was doing science experiments on an app on her school ipad. I watched her for a few minutes before deciding we could do an exciting experiment of our own in the kitchen. So, we gathered the ingredients for sherbet and measured and tasted and mixed. This recipe made enough sherbet for S to take to school with a packet of plastic spoons so all of her class mates could try some too.

S’s advice is not to taste Citric Acid on its own.

My advice is not to take a big teaspoonful of sherbet unless you enjoy foam coming out of your nose.

3 Tablespoons citric acid
1 Tablespoon bi-carb soda
10 Tablespoons icing sugar

Push all of the ingredients through a sieve and then mix really, really well.
