al-Warraq is pretty explicit that it's leavening. In one of the
recipes, discussing what can go wrong, he mentions the possibility of
dead yeast and suggests adding more buraq to make up for it.
"If the yeast was bad, add some more borax to the batter." (p. 415)
Nasrallah says it was also used to give bread a shiny surface, but I
don't think there are any recipes in al-Warraq that do that. Any guess
what that might imply about the nature of bakers' borax?
