I'm a single girl, who likes to eat but it's challenging to cook for one. Recipes are designed for families of four. Package sizes at the store are too big to use for one person. Leftovers are depressing. No one to make "mmmm" sounds when it's really good. The list goes on. There are some benefits, no one to complain when it's bad, and only one person's likes and dislikes to accomodate. Big pluses.
My mom, is actually a chef, she runs her own catering company, so most of my kitchen education as a kid involved watcthing from the bar while I talked to my mom or her kicking me out of the kitchen. She made it look so easy. She never measures and it's always amazing, I call her the "approximate chef." It gave me impossible standards, which I did not realize until I grew up and figured out that not everyone has these amazing abilities.
So the goals are to cook for one person (maybe with leftovers to take to work for lunch the next day), save money, cut out food waste where possible, and make lots of "mmm" sounds, even if no one else around to hear it.
