Back to the butter - do you buy it in tubs like margarine or just in blocks? I do buy butter in 250g blocks for baking - is this what you use?
Yep, that's what I get, the same ones I use for baking. And I get the unsalted one. Much cheaper than actually buying a tub too!


How do you know if it's rancid and how do you stop it from happening? Will have to get a butter dish thingo, I don't have one.
There's only 2 of us and I just put a whole block in the container and leave it out of the fridge and we never have any problems!
