Over the years, there have been many posts on this subject complete with math breakdowns showing how many plates we can sell per hour and how many coins we can earn per day. While I like earning as much as the next gal, I honestly can't be bothered to go that far into detail (I barely have enough time to finish my remodels, lol) but thankfully other dedicated players have done so and shared
When the goal structure changed I realized I wasn't earning enough to sustain my daily playing habits comfortably so I poked around and found some great older informational threads. In the end, I found that picking a few recipes with higher yields/earnings to serve continuously combined with optimal seating is the key for my bakery. Once I rearranged my set up and picked which recipes to use daily I noticed a marked increase in my daily earnings - it honestly surprised me how much of a difference it made. Of course, the details will be different for every player since there are several factors to consider but I recommend reading through some of informational threads to give you a better idea of what those factors are and how to best organize your playing.

P.S. Don't be put off by the age of these threads or if it's marked as an RS thread, I've found that the information included works for both games and is still accurate for the most part. I have these pages bookmarked and refer to them frequently even after years of playing.
