Eggs will whip with the most volume at room temperature. It’s best to separate them cold from the refrigerator and then let them sit out to warm for about 30 minutes before whipping.
Preheat the oven to 250°F (120°C). Line 3 large baking sheets with parchment paper. Trace twenty 2 to 3 inch (5 to 7.5 cm) circles on the paper, and then turn the paper over to avoid contact with the ink and batter.
