How do you eat your bread with butter? Do you have some room-temp butter always out in a butter bell, ready for spreading? Or do you do the attempt-smearing-cold-hard-butter-on-to-poor-toast method? Butter bread, and then toast for more even butter coverage?
And of course, the type of butter you like is important too in this simple pairing. Anything from the supermarket? Butter you make yourself? Fancy European butter? Salted or unsalted?
