Cooking tips:1. The quality of commercially available brown sugar is not stable. Some are coarse, some are fine, some contain a lot of impurities. Therefore, it is better to use the home grinder to grind brown sugar into sugar powder first. If there is no grinder, it must be screened before use.. 2. The addition of egg liquid must be carried out in several times. Each time, stir until the egg liquid and butter are completely integrated and then add the next time. Otherwise, it is very easy to separate water and oil. It doesn't matter if water and oil are separated. Just add 1 teaspoon of low flour and mix well. But this is the remedy. Mix well in several times. 3. Butter won't taste good until it's filled with biscuits. There are skills in making delicious dishes.
