Yes I shared Meringue recipes before but sometimes you have a complete sweet table to prepare and don't have time to prepare everything from Scratch. I love it when I find products like this Easy, Delicious and Quality products.
From "Scrapcooking" I tried the white Meringue Mix (Exists in Pink too but I love white since you can color it).
Just Add water and mix (I did leave the mixer on for 10 minutes)
So yes you can color it with a drop on americolor.
And you can even add a drop of Lorann Gourmet Oils at this step
Mine were not colored at this step but I did add a drop of coconut in the mix
For the 2 or 3 colors effect on the meringue, add a drop of color on the side of your bag from americolor and then add your meringue in the icing bag before piping.
