First, we will prepare the egg whites. I'm using 3 egg whites here. beat the egg white gently, careful not to overbeat them to the point of having a layer of froth

step two. prepare the milk. for every egg used, measure about 100-120 ml of milk. here I'm using 350 ml of milk. add in 2.5 tablespoons of sugar and mix well.  microwave it for 1 minute to a min and a half. until the milk is 50-degree celsius

step three, combine the milk and the egg white together and sift it once. pour them into 2-3 cups or bowls. cover with a lid or some aluminum foil

step 4. place the bowls into a boiling steamer and steam on high for 15 minutes. then turn off the heat and cover the lid, after 5 more minutes it's ready. because different sized containers will affect the length of the steaming process, keep a close eye on them during this step.
