Cocoa Powder in Icings
Have you ever noticed that a chocolate icing (either glace or buttercream) made with cocoa powder sometimes needs a different amount of liquid to reach the same consistency as last time you made it? It seems strange, but there is a very simple explanation…
Different brands of cocoa powder, and even different batches of the same brand, can have a different thickening ability. So, when making your icing, start with a little less liquid than recommended just in case it doesn’t need as much, but also don’t be surprised if it needs a little extra to reach the right consistency (¼ teaspoon extra is often enough to do the trick).
