To make silver star recipes, open your Farm Kitchen and click on a recipe that has a silver star icon.
Then, make sure the option at the left with the silver star is checked — otherwise you will make the normal recipe and it will not count for special orders.
Delivering the special order
The quest “Bland No More” asks you to deliver an order for recipes with silver star crops and herbs. It should look like this. Again, it will require recipes, not starred crops only like the order from the Fancy Restaurant.
The Chef order for silver star recipes from the Restaurant is generated every other day even if you delete it, until you complete the quest.
