You can use butter, but it’s a different result, in the same way that you don’t fry potatoes in butter to make french fries. With something like a grilled cheese, the butter or mayo used to toast the bread becomes part of the flavor profile of the sandwich. With fried toast, I’m looking for a solid, crispy texture for the bread.

You can compare doing the same things to potatoes: Chunks of potatoes sauteed in butter with golden edges are not the same product as french fries fried in oil.

There’s no wrong between the two, butter and oil. They both make delicious sandwiches. But they are different.

Whoa. I was today-years-old when I had to look up EVOO and now I feel both more informed and slightly well-duh. This is going to be a new favorite.

Thanks for the update, hoping the next investigation is good news.
