Hmm I always hated dealing with the cold butter on toast problem as a child. My mom started to whip butter she bought from the store, and this solved that problem at the expense of her effort.

Butter that you squeezed out of a plastic bottle... that went a little too far for me.

I don't use butter at all now except for cooking. Usually, I prefer cream cheese, maybe with some Aromat, on a toasted bagel. Mmmmm.
