This looks like an interesting kind of bread. I'm not interested in bearnaise sauce but I'd like to try this bread despite hating mustard. Omit the wheat gluten if using bread flour. Prep time is the dough cycle, mine's 90 minutes. Admittedly, the first thing I thought of upon seeing this recipe was "Don't get saucy with me, Bearnaise!" from History of the World Part I.
