I need to color royal icing black so I can do some piping. Is there a base color I should start with so I get a true black. It seems that I remember that just starting with black will give you dark gray. Please offer me some help.
I think you are supposed to start with a chocolate BC frosting. Then you add the black coloring. Let it sit overnight so that you can see if you need to add more black. It may lighten up as it sits.
I normally don't start with a base color. When I color my icing black, I put in quite a bit of color to get it black.
I don't ever use a base color for coloring the royal icing black...I just use a lot of black....add a little, mix, add a little more, mix, add a little more mix. It's true that the color will come in more after some time but I never wait for that time to come...I just add the black until I get the desired tone.
My practice is the same as Bubba01. I just put a good amount of black into the royal icing without using a different base color. It really doesn't take too much of the black...about a half a bottle per 2 cups (that is a guesstimate )
