Pull the green hulls out of the strawberries. If they are still quite hard, cut them in half or quarters with a table knife. Tip them into a flat-bottomed dish.
Use a potato masher to squash the strawberries as much as you can. Tip into a bowl. Ask your grown-up helper to give you a hand if you need to.
Add the mascarpone and mash this in – don’t worry if it is a bit lumpy. Add the condensed milk and mix everything together. Don’t worry if the mix is streaky.
Spoon the mixture into a metal or plastic box and put it in the freezer. Wait until the next day or at least 6 hours before scooping into bowls or cones. Decorate how you like.
Top tip for parentsThe riper the strawberries are the more easily they will mash and this makes a really good way to use up older strawberries. If your child is not able to cut with a knife, then roughly chop the strawberries for them. You can also use raspberries, ripe bananas, peeled peaches or nectarines for this recipe.
