Kitty Travers specialises in delicious ices which she makes at home and stores in a freezer in her bedroom.
Her ices aren't made with commercial ingredients, and the flavours shine through.
Her flavours include pumpkin "mini-milks" infused with fig and peach, and this fantastic lemon granita. See lagrottaices.tumblr.com.
250g granulated sugar
The juice of 10 large lemons (plus the zest from 5 of them)
Put the water and sugar into a saucepan with the lemon zest, bring to the boil and stir until the sugar dissolves; simmer for a minute.
Remove from the heat; cool. Stir in the lemon juice; transfer to a shallow, non-reactive container; put in the freezer for about 4-5 hours.
Stir the granita every so often so that it doesn't freeze into a solid lump (you want the consistency to be a little granular).
Once frozen, break the ice up into small pieces; return to the freezer, then after an hour break it up again; then serve.
