1, butter becomes soft at room temperature. Just press the scraper easily without resistance. Mix 80 grams of powdered sugar evenly, and then beat the butter to white, about twice the size.

2. Add the egg liquid in three times, totaling 30g. Every time, before adding the next egg liquid, mix it with the whipped butter.

3. Stir the egg liquid+butter until feathery, and don't separate the oil from the water.

4. Sieve the flour, add salt and mix well until there is no dry powder dough.

5. Add mozzarella cheese and continue to knead into dough. Cheese is evenly distributed in the dough.

6. Put the long strips after brushing the egg liquid into the oven, and control the fire up and down 160 degrees 18-20min. Master the temper of the oven by yourself. Don't go away, take them out after painting.
