This comes from my children’s cookbook Lookit Cookit. Any child would love to make it - it involves mashing, squashing and stirring. And when they’ve tasted it, they’ll never want to eat a shop-bought one again.
If it’s not obvious from the pictures, you can find out more (and get dozens of other ideas for games and experiments) by buying the book. It’s available on the iPad here http://bit.ly/15iTHZB and as a paperback copy at www.lookitcookit.com
You don’t have to be a child to appreciate this. It’s perfect, light food - summer in a bowl.
