How to make rhubarb granita

A rhubarb granita cools and refreshes, combining the childlike joy of a frozen dessert with sophisticated, tart rhubarb flavours. Unlike sorbets or ice cream, granitas do not need to be churned and can be made in any household freezer. The blush pink ice makes a beautiful dessert, palate cleanser or a simple snack on a sunny day.




  • 250g of caster sugar
  • 250ml of water
  • 800g of rhubarb


Place the rhubarb, sugar and water in a pan and bring to the boil. Simmer for approximately 30 minutes until all the rhubarb has broken down
Leave to cool slightly then transfer the rhubarb into a fine sieve and let the juices drain into a bowl
Pour the liquid into a flat container and put into the freezer. Stir every half an hour until completely frozen


Emily Watkins tops a baked custard with rhubarb granita for a playful twist on ‘rhubarb and custard’. Just as Watkins uses it as a layer, a strongly flavoured granita is a good way of introducing new flavours to an ice cream sundae or frozen dessert.

Rhubarb granita makes a delicious and refreshing dish in its own right, and would make a lovely summertime palate cleansing course served in a shot glass.
