I have attempted Sourdough Banh Mi (Vietnamese Baguette) several times with egg, eggless as well as egg white only and also with Yudane and Non-Yudane Method. I found that the recipe with egg is probably better as I get a more fluffy crumb. The texture is very soft, fluffy with crispy crust. The crust is very crispy and it stays for few hours (around 2 hours for our tropical high humidity weather here). Please toast the bread to restore the crispy crust if necessary.
