Cooking is both art and science, and the fine points of how a dish is prepared determine both its style and ultimate quality. But consistency can be a problem. Lisa ­Huang, president of He Yuan Foods, turned to the manufacturing sector for a solution. By applying the sector’s standard operating procedure (SOP) model to the “production process” at her Easy House Vegetarian Cuisine restaurants, she has created a vegetarian powerhouse with a reputation for reliably outstanding food.

The chain’s process checklist, which covers more than 100 items, is incredibly detailed. There are instructions on how to select, chop, and cook ingredients, as well as on seasoning, plating, and serving. Every step is specific and quantifiable. The amount of sauce to sprinkle, the thickness of the pieces of corn on the cob, the number of grams of lettuce, the arrangement of the fruit… workers are expected to follow the instructions to the letter.

Most restaurants have a sign on the wall stating that menu photos are “for reference only.” In contrast, Huang says that Easy House guarantees to serve its customers dishes that look just like the photos.

Taiwan’s vegetarian restaurants have undergone a massive transformation over the last dozen-odd years, with more and more opening up at the high end. The Chinese-style vegetarian cafeterias of yore have been “upgraded” to Japanese-, French-, and Italian-style venues for fine vegetarian dining, ushering in a new era in vegetarian eating by helping the practice shed its religious associations and expand its clientele to consumers interested in healthy eating.
