Thinly slice the cucumber and onion and combine in a bowl.
Chop up the dill and put it in. Give it a pinch of salt and pepper, and a big pinch or two of sugar.
Splash in maybe a tablespoon each of vinegar and oil to start with. If replacing the oil with sour cream, you might want about half a cup (120 ml).
Stir thoroughly and let sit in the fridge for a few hours, or overnight. Stir again and taste. Add more of whatever it needs.
