Recently, Kristin and Sebastian gave me an all-things-banh-mi cookbook titled The Banh Mi Handbook. For me, it turned out to be the perfect sort of gift; something you never knew you wanted, but turn out to love.
Flipping through, it was clear how all the individual components were perfectly manageable, and most could be made ahead. Plus (yay!) it included a recipe for the soft, steamed variation of buns, which I think are the perfect size for experimenting with topping combinations.
