Put everything except the vanilla and strawberry jam into the top of a double boiler (or in a large metal wide-mouthed mixing bowl) with simmering water beneath. Start beating immediately with a hand-held electric mixer or hand-held egg-beater until the mixture forms stiff peaks.
Remove from heat, add flavoring, and keep on beating. Stir in jam. The mixture should be
quite soft. Allow the mixture to cool. *Note: my jam was homemade and quite runny. If your icing is too soft to “flow”, try adding little teaspoonfuls of milk/cream and stir until you get the desired texture.
Spread over the tops of cupcakes, pushing icing to the edges of the cupcake liner to fill
completely.
