To use whole milk, the higher the fat content, the better 2. milk can not be boiled, otherwise the milk skin formed too early will break, hot milk should be left for a while, so that the milk skin has time to fully coagulate. 3. to be slowly simmering with slow fire, the milk is just all coagulated immediately turn off the fire, the old eating taste is not good; the lid of the pot to leave a gap, if not left if the water vapor drips to the top of the pimple; in the milk pot to heat up a bowl of milk, and then pour into a small bowl and wait for cooling. Pour into a small bowl and leave to cool. Fill a large bowl with egg whites (one large and two small), sugar and stir. When the milk in the small bowl has cooled, carefully pierce the skin and slowly pour the milk into the large bowl. If done properly, the skin will lie securely on the bottom of the small bowl. Then whisk the egg whites, sugar and milk in the large bowl and slowly (always slowly) pour it back into the small bowl. If done properly, the crust at the bottom of the small bowl will rise up and cover the mixture. Add to the pot and steam. Rise the pan at the right time, and cool again while you wait for a new milk skin to be created. This is double cream,. (*^__^*) Hehehe! I hope you'll take it! I know that's all.
