I agree, sour cherries.

Sour for me, too, maybe sweeten them or not. The powdered milk must be to stabilize the icing. I add 2 tablespoons of instant vanilla pudding which works great to keep the cream fresher longer.

The recipe says black cherries. Those tend to be sweeter but sour are prettier.

Another great icing and one I use on red velvet cake is Joy of Baking mascarpino cheese and whipped cream sweetened with powdered sugar, vanilla, (I'd have to look it up again.) but it's gorgeous and so tasty.
