I take food color with qtips and run colors along the cookies gently. Works quite well.Dehydrate 150F for about 6 hours, take out let cool. These can be done in oven at 200 for 1 hour and 1 hour left in oven with door stayed closed after cooking. We make this every Christmas
Did a few without the food color as well! Great way to use up some egg whites.
It’s half the price compared to the leading Dehydrators and works just as good!
