This is what I eat, when I'm not entertaining. I mean that literally: this is ALL I eat when I'm not entertaining. It doesn't bore me, and is impossibly-easy. I make a big pot and it changes as the week goes on. This is about the loosest-ever recipe imaginable.
Here are the ingredients: Rice, good stock, whatever.
It's typically made with short-grain white rice, but I prefer brown basmati. Grab anything and you won't go wrong. It needs good stock, so if you don't want to make your own, get a jar of Better 'n Bullion, which comes in chicken, beef, ham, seafood, mushroom, and some other vegan flavour I haven't tried. It's better than any canned or boxed stock I've had, and is almost shelf-stable. (The ham and seafood ones are particularly good.)
Make it with four times as much stock as the rice needs. Green onions are a natural. If you throw in more fat ginger slices than make any sense, it will even cure anorexia. (Pick them out before serving.) If you can find smoked haddock you are in heaven. (It freezes well, so ask at your supermarket fish counter. If you grab some, know that it stays fresh for a month in the fridge once defrosted.) Smoked salmon would not be a disgrace. Tofu is brilliant, but serve it in bowls and pour the congee over it.
I like to add caramelized onions and carrots, and throw in some foraged mushrooms while it bubbles. This is a recipe that is impossible to get wrong, and can be a complete balanced diet.
