Rainbows are seasonally appropriate for every season! They never go out of style.
I'd like to see a crew of fashion designers work with a bunch of pastry chefs to design amazing desserts. We could mash up Project Runway and one of those Top Chef whatevers and make a kajillion dollars! I could see this as Betsy Johnson's entry for a super simple petit fours.
Finger jello is super fun even when it's only one color and just hanging out by itself. Taking the extra time to layer a whole bunch of colors in there takes it to a whole new level of snack innovation. I wonder how it tastes with all those flavors in one mouthful? Like a rainbow of fruit?
I love a repeating pattern, especially on food. Even better when it's done with something as delicious and natural as blueberries. Nothing fussy, no artificial coloring or hours slaving over perfectly smooth icing, just a fantastic and undoubtedly delicious polka dotted tower of celebration. I'll toast to that!
