The Secret to Costco's Delicious Pizza Is a Sauce-Dispensing Robot

Deliciousness often comes from unexpected sources. Take the food court at Costco, for example: No matter which location you're shopping in, you can always count on the pizza there to taste better than food served at a big box store has any right to be. Reader's Digest recently revealed the secret behind the chain's confounding culinary consistency: pizza-making robots.

Rather than relying solely on human employees to assemble the ingredients, Costco has perfected the art of pizza preparation with a machine that makes each pie identical to the one that came before it. Each Costco pizza starts with dough that's had sufficient time to rise and achieve chewy, pillowy goodness. From there, an automated nozzle dispenses an even layer of pizza sauce over a spinning, uncooked crust, and then the cheese and toppings are added with painstaking precision. "Every Costco pizza you get should have the same amount of sauce, cheese, and toppings,” Costco employee Kaiwen Zhao told Reader's Digest.

The final step takes place in the oven: The pie is blasted with heat from all angles and emerges from the oven exactly six minutes later. If the pizza isn't purchased within the hour, it gets tossed and replaced with a fresh one.

Surprisingly, Costco is one of the biggest pizza franchises in the country, with nearly 500 stores serving up the famous pies. But pizza isn't the only menu item that keeps customers coming back to the food court: Costco's rotisserie chicken is so popular that it has its own Facebook fan page.
