[0002] With the development of network technology and recommendation systems, users can obtain recipes, cooking methods and lists through various software. However, in daily cooking, it is often found that some seasonings or side dishes are missing when cooking according to the recipe list, and these seasonings or side dishes can sometimes be omitted or replaced.
