Tortilla selection at scale — what I learned running a food stall

After testing eight different tortilla suppliers for a three-day festival I have real data. The criteria that matter at volume: tear resistance under steam, flexibility after resting on a warm surface for three minutes, and seal integrity at 250g fill weight. Three of the eight failed at the steam test — they got sticky and tore when stacked. Two more failed the seal test at 250g. The remaining three were comparable in performance. The price difference between them was 40%. My takeaway: the cheapest option that passes all three tests is the right choice. Above that threshold additional cost does not improve results.
