Put the rice in a large pan with 500ml
water and the lemon and orange zest.
Bring to the boil, cover, lower the heat,
then cook for about 15 mins until all the
water has been absorbed. Uncover, stir in
the milk and sugar, then simmer for 20-25
mins, stirring often, until the rice is
tender and sauce thickened. Cool,
then leave at room temperature.
