Man, pancake batter can really take some color. I was pretty excited by the way the colors turned out in the Taco Platter (Dec. 13, 2009) and the Corn on the Cob (Feb 16, 2010) but they're pretty wimpy when you quit messing around and add some more food coloring. These look like foam rubber. The color did not mess up the taste.
One trick to keep the color from browning as you cook these: Keep the griddle a little cooler than normal and let the pancakes cook slowly.
I need to say thanks to Carl for coming over and taking the photos. My camera has died. Carl did that fancy out of focus thing on the Roy G. Biv pancake.
