Now that the dough is in three portions, it's time to make each of them specialized. There will be green lemon-flavored cookies, yellow orange-flavored cookies, and pink peppermint-flavored cookies.
Prepare the next round of dough: This will be orange rind and yellow food coloring. Do the same as the previous set of directions. Finally, for the last one, work in the extract and the red food coloring. Chill all the doughs in their wax paper tubes overnight.
The next day, preheat the oven to 375º F and unwrap the dough tubes and roll them a little so they soften a bit and become round again. Next, take the green dough and spread the nonpareils on the wax paper to roll it in so it collects a nice coat all over the outside. Hint: It helps with handling a little if you cut the tube into maybe three pieces and roll each individually. After it's coated, slice 1/8-inch slices with a sharp knife. It helps to keep rolling the tube as you're cutting so the cookies don't become non-round. Sometimes with the green dough (and also the yellow), it might help with handling and making smooth cuts if you flick just a little water onto it (a half teaspoon or so).
The yellow dough should get rolled in finely chopped almonds and subjected to the same treatment, and the pink should get rolled in the colored sugar. The cookies should be baked for 7 to 9 minutes. They have a tendency to burn suddenly, so make sure you check them once a minute if you see they aren't done after 9 minutes.
