Great intel Derek. OK, the seasoned pans have some significance as evidenced by BB's "new takeaway/just like ours" observations.
Great idea to have him review the Saffron base. Worth asking him also how much he makes at a time. The Saffron may be scaled back, and they may use a larger pot. Some have suggested the sheer scale is an important factor in hitting BIR taste. Also have him critique the method (boil the veg, add the spices, blend, simmer....)
