Set an egg
waffle machine and set to 400°F (200°C). Grease lightly with oil. Add about 1 cup of batter to the machine and cook for 2½ minutes, until crispy and slightly brown. Using a rubber
spatula, transfer the waffle to a
wire rack to cool slightly. To achieve a round shape, lay the waffle over a curved surface, such as a
rolling pin, to cool. Repeat with the remaining batter.
