Custard Sauce from Food.com: Custard is a British institution! Sponge puddings and crumbles just wouldn't be the same without it! This will make a custard of a pouring consistency. IMPORTANT: In order to have a smooth (not lumpy) custard, use a heavy-bottomed saucepan, and stir constantly! If you have to walk away from the stove, remove saucepan from heat.
This sauce is served over steamed puddings, fruit crisps (crumbles), and any dessert that would be enhanced by a creamy vanilla sauce. It's the perfect homemade replacement for Byrd's Custard powder. One warning, however: 1) use a small, "thick-bottom" saucepan, and 2) cook over low heat and don't allow the mixture to boil or it will curdle! If it does curdle, you might be able to salvage it by blending briefly in a blender. [Measurements are U.S. Standard}
Irish Apple Cake with Custard Sauce ~ The cake is excellent all on it’s own, but what really turns it into a decadent dessert is the custard sauce. Poured warm over the top of a slice of apple cake, its creamy sweetness is the perfect addition to the thick fruit filled cake.
