Secret Foolproof Chocolate Glaze (Icing, Frosting)
100 g, I used 43 % cocoa
vegetable fat or margarine
optional: 2-3 drops vegetable oil
Melt vegetable fat and chocolate (and oil, if you want to make your glaze shiny). My favorite method is using double boiler, but I believe microwave would work, too.
Whisk until smooth and pour over cake. Let cool.
