pizza: It is said that pizza hut and many companies keep their recepies very confidential. Even if the coock changes, due to fixed preparation method, the recepie doesnt change its taste much.But how is it possible to keep the preparation method confidential and get the pizza prepared by any coock?|||They keep it confidential by not publishing it. They do have it printed in each restaurant. And it's spelled RECIPE, and COOK.|||If I can elaborate and expand on TJ. A lot has to do with supply, certain ingredients, come from different suppliers, to one main warehouse, Then Pizza Hut's logistics contractor would only need to pick up from one warehouse to deliver to the Pizza Hut outlets. The sauce used to be, Step 1. Open one can of tomato. 2. Empty sachet of herbs into sauce 3. Stir well 4. Keep refrigerated, use in small batches. Now I believe it all arrives in vacuum bags, all premixed. The trays of pasta and Lasagna are not prepared at the individual outlet, but at a major kitchen. Snap frozen and delivered to Pizza Hut Distribution Warehouse.
