For others in parts of the northern hemisphere where it's fresh berry season, because it's one of those things I know but forget too often myself:
You might see that pint of tasty fresh looking berries and think "those look great but I know I'll not eat them all before they go bad." Ignore that thought and buy that those berries. Heck, buy two portions. Eat as many as you want fresh that day.
With what's left, combine in a saucepan with a about two tablespoons of sugar (give or take depending on the sweetness of the berries) and a tablespoons of water (or brandy if you're feeling fancy) for each 8oz of berries. Bring to the boil and boil hard for about three minutes, reduce to a bare simmer and bubble away another ~10-15. Cool and keep in the fridge and put on everything for the next week (it'll keep at least twice that and probably longer but in my experience won't keep around that long).
A quick compote like this keeps a lot of the fresh flavor so you're still getting the benefit of tasty seasonal fruit without that "I ate twelve berries and let the rest turn to moldy mush" guilt.
