Put maple syrup
in a small saucepan and bring to a boil. Boil hard until reduced to 1/2
cup (125ml), about 15 minutes. Add gelatin to cold water and let stand 5
minutes. Add to hot maple syrup and stir until dissolved. Pour this hot
mixture gradually into egg yolks, beating constantly. Add softened ice
cream and blend well. Pour into four custard cups or 4-oz (125ml) moulds.
Freeze until firm. Unmould to serve.
