By the way, we mainly use Butter Soft, because it's spreadable without having oil added.
But, I want to buy organic butter from now on (it's so much tastier) aand that is soooo hard to spread. One thing that helps: buy (or bake) decent bread!!! Sorry, I am a little biased. I grew up in Germany, where we eat mainly bread that is a little firmer and denser (and often rye) than the typical Aussie bread.
The other thing is to try and plan ahead a little. Taking your butter out of the fridge 10 minutes before using it, makes a huge difference.
If you're like us and don't eat huge amounts of bread, you mgiht store it in the freezer. I take one slice out and butter it while it's still frozen. It's much easier to spread the butter on the hard frozen bread.
