Some are excellent cooks. They can make something grand out of ordinary things. On the other hand, many can’t cook worth a lick. There are also those in the middle: with the help of recipes, they can put palatable food on the table.
Your protagonist might have secret talents that aren’t revealed in the story, but that influence his actions in some way. For example, he meets friends for lunch at a fancy restaurant. He’s the only one that understands the names and descriptions, surprising everyone. From there perhaps he invites them over for a gourmet dinner.
Or maybe he’s so clueless about the menu that he selects a simple salad, trying to be safe.
Your task is to write a story that involves food in some way. If your character is a marvelous cook, write a scene in which something happens that alters the taste or consistency of the meal. You can do the reverse with the lousy cook: she concocts an entrée that’s the hit of the pot luck.
Description is important, but build tension through dialogue. There must be conflict of some kind, either internal or external, or even both.
Have fun with this one.
