First, for the love of wheat, it's "banh mi" not "bahn mi"! The
pronunciation may SOUND like "bahn", and there may be a zillion
instances of it spelled "bahn", but I can assure you that "bahn" is
wrong and that it's "banh".
Second, search around for recipes for baking banh mi. There are a
non-trivial number of banh mi recipes calling for rice flour or for a
paste of cooked rice and water. I used to think that rice anything
can't possibly work in baking any kind of bread but I have baked banh
mi with rice paste added and the result is surprisingly light and
airy and thin (but crispy) crusted, as "authentic" banh mi should be.
Third, this recipe SEEMS a little short on water. If anybody try
this recipe, I'd be interested in knowing how the crumb turns out,
whether it'd be more "hearty" than the usual banh mi.
