Heat with an electric baking pan, spread the egg tart on the electric baking pan, and turn on the heating button for 5 to 10 minutes.
Some students and friends who live in the dormitory can heat the egg tart with a rice cooker, lay it flat in the rice cooker, then press the cooking button and wait for it to jump up automatically, which will take five minutes. In this way, the egg tart is evenly heated and the flavor remains unchanged.
