1. You will get the orange color only if you use food coloring. Using gel food color will ensure that you no additional liquid is introduced in the batter. If you do not have orange color, use red and yellow together to get orange.
2. You can use the same recipe to make lemon or lime cookies. Use lemon or lime juice, zest and extract in place of orange and add yellow food color or a pinch of turmeric for color.
3. Sometimes, the powdered sugar coating will simply dissolve and bake right into the cookies. Rolling the dough in granulated sugar first helps keep the powdered sugar from disappearing into the cookies completely.
4. The prep time given here doesn't reflect dough chilling time, so plan your time accordingly.
