Want an easy way to get the kids in the kitchen, experimenting with flavours and sensations? Let them try making their own sherbet.
By mixing some citric acid with bi-carb soda they'll create a fizzy explosion in their mouth. They can also play around with different kinds of jelly crystals to make different colours and flavours.
Easy sherbet recipe
Adapted from Science by Email from the CSIRO
Serves 2–4 kids
- 1 teaspoon of citric acid (this is available at your supermarket)
- 1 teaspoon of bi-carb soda
- 3 tablespoons of icing sugar
- 2–3 tablespoons of jelly crystals (your prefered flavour)
- Mix all of the ingredients in a bowl.
- Take a pinch and taste.
- Add more bi-carb soda or citric acid if you want it to be fizzier or more sour. If you want it to taste sweeter, add more icing sugar.
- Once you have the sherbet flavoured to your liking, eat it or package away for later in an air-tight container. Make sure you don't let moisture get into it.
A little science in play
The sherbet recipe is actually a little bit of science happening in your own kitchen. The CSIRO
"When you combine an acid (the citric acid) and an alkaline (the bicarbonate soda) with saliva they mix together to create a gas in the form of lots of tiny bubbles. This is called an acid-based reaction and it's what gives sherbet its fizz. You are actually feeling the sensation of carbon dioxide bubbles on your tongue. These are the same bubbles that are in fizzy drinks."
quick gift idea
Making your own sherbet is also a great gift idea for kids and kids at heart. Make up three or four batches of sherbet using different jelly crystal flavours (this will also give you different colours). Take each sherbet mix and layer the different coloured powder in small jars or food gift bags and tie off with a ribbon.
