Sims don't auto cook if food is in the fridge and instead prefer to eat the leftover. Keep in mind if you use my "No Auto Food Grab" Mod: That Mod will stop Sims from getting leftover autonomously when the "prevent buff" is active (The Autofill Button in the UI is autonomous behaviour as well). If that is the case you need to manually send them to get leftover."
This is a spice ingredient that can be used in my other food and crafting recipes. Sims can purchase this item via my Brazen Delivery service or they can craft it on my Mill appliance. Each sack can be separated into 8 spice bottles that can be used as an ingredient.
