Heat the oven and prepare the vegetables
Heat the oven to 425°F (220°C), with a rack in the lower-middle position and space above it for the batter to rise. Wash your hands with soap and water for 20 seconds. Rinse the onions and cabbage under running water, remove damaged outer layers, and dry. Peel and thinly slice the onions. Core the cabbage and cut it into strips about 1/2 inch wide.
