Rainbow Cheesecake

"For this Rainbow Cheesecake, I went with my go-to cheesecake recipe, but I pulled out the food coloring. Actually, I pulled out the color gels. If you bake a lot, then you’re probably already aware of the advantages of gel-based food colorings. Instead of dropping several liquid drops of food coloring into a recipe, you swipe some of the gel into the recipe using a toothpick. (Make sure to use a clean toothpick if you want to add more gel – a container of food gel will last a long time as long as you keep it clean!) Food gels offer more vivid colors, and the colors tend to hold a lot better after baking. Traditional food coloring tends to fade in the oven. "
