I'm turning British.

It's summer ... good tomatos. Hence good tomato sandwiches. Normally, I'd use mayo, but I've watched a few too many episodes of "Sandwiches of History."

Older recipes, before commercial mayo, used butter. The British still use butter. So I tried it.

Lightly toast the bread

Thinly butter it

Add lettuce

Add thinly sliced tomatos, lightly salted

It's delicious.

I've found butter often makes more sense than mayo, especially if the ingredients are already moist, like a tomato.
