Everything is made "by hand"
While everything at Taco Bell is clearly not made from scratch, every single item is put together ingredient-by-ingredient by the hands of the line workers. (Don't worry, they wear gloves.)
"Think about making something at McDonald's. You have the patty, the bun, the cheese, maybe a couple pickles, and a squirt of ketchup. It's not super-uniform. But at Taco Bell -- with the weighing at the end, we need to be totally precise with everything we put inside our food. And we use our fingers to do that, after training with a digital scale, of course."
Each item has a strict formula that line workers need to follow.
"For example, a crunchy taco is one scoop beef, one finger pinch of cheese, and two finger pinches of lettuce. If we want to make it supreme, we step it up to two finger pinches of cheese and three of lettuce. Really, we are just adding more fingers, but once you're trained in that method, it becomes second nature. This type of exactness makes sure almost all of our stuff comes out looking the same, no matter where you are or who is making it. And everything we make is just like that, measured by hand, put together by hand, and weighed before it reaches a customer."
