Chestnut, Walnut and Orange Ice Cream

• 2 oz (50 g) walnut pieces
• coarsely grated rind and juice of 2 large

Put the walnut pieces into a little water in a saucepan, boil for about 10 minutes and drain. (This will make the nuts moist.)

Put the eggs into a bowl with the salt and whisk with an electric whisk until pale and frothy. Put the demerara sugar into a saucepan and add the orange juice and water. Dissolve the sugar, stirring over a low heat. Add the grated orange rind, bring to the boil
