Buns Air. Soft and delicious that just a fairy tale (even on the second day!)

Airy fast buns in the oven. Even on the second day they are as fresh, and maybe even tastier! We prepare dough for buns without egg white, which allows baking to remain for several days without loss of taste and structure. The dough is without a doubt ideal for any product, I will only be glad if you cook! Follow all the recommendations and you will succeed too.
