No Sugar Custard

6 egg yolks
1/4 c. Fruit Sweet
1/2 c. flour
2 c. milk
1 tsp. vanilla
1 tbsp. butter

In a medium bowl, beat egg yolks and Fruit Sweet until thick and pale.
While continuing to beat, gradually sift in flour.
Pour into a saucepan and place over low heat on the stove and gradually add milk and vanilla.
Cook, stirring constantly, until mixture has thickened to a custard consistency, about 15 minutes.
Remove from heat.
Melt butter and pour over custard to prevent a skin from forming while it cools.
