You open the fridge and put the food in it and its used to cook stuff, like you can only
cook "mac and cheese" or something, but you can cook cookies, fish, and other stuff..

It all depends on what you are trying to do. Go to any object that has to do with cooking
(stove, grill, fridge, food processor, etc. ) an it will give you several options oon how
and what you want to cook. You can learn several recipies buy reading their books. If you
want to take leftovers out of the fridge and serve you can by going to buy/build mode, go
to inventory and chose the food tou desire to take out. If you want to sell food you can
go to the fridge and choose sell or you can go to the grocery store and they will have an
option where you can sel fish meats and produce. If you want to plant food. Go to
buy/build mode and place a seed or whatever food you want to plant on the ground. In live
mode click on the desired food and it will say plant here unless you are not at a certain
gardening level yet. But in the game you can plant and grow any food from vegetables,
fruit, meat, fish, even money lol. But you have to get your gardening level up and green
thumb helps too.
