Makes enough for 5-6 servings
1 cup sugar
3 tablespoons Rumford Cornstarch
1 cup milk or cream
2 cups fresh orange juice
1 tablespoon orange zest
2 tablespoons lemon juice
In a medium saucepan, stir the sugar and rumford Cornstarch together and add the cream or milk. Heat over medium low, stirring constantly, till it comes to a very low boil. Stir constantly for 2 to 3 minutes and remove from the heat. Pour the mixture into a small bowl and press plastic wrap directly on the surface. Refrigerate till completely cooled.
Whisk the cooled cream and cornstarch mixture with the orange juice, orange zest and lemon juice. Pour into the container of an ice cream maker and freeze according to the manufacturers instructions. Transfer to a large airtight container, cover and freeze for several hours or overnight. Serve frozen.
Use fresh squeezed juice for the best flavor, store bought or made at home. For the dairy, cream will taste much richer and yield a creamier texture. For a lower fat content, milk works fine yet results in a slightly grainier texture.
