So, opening the book at random ...
I'm sure most of you are familiar with the peanut butter and banana sandwich ... just slap some peanut butter on the bread and slice a banana, right? Here, from the book (which devotes a half page to how to butter bread properly when making a sandwich), is a classier way to do it:
1/2 cup peanut butter
1/4 cream or hot water
1/2 cup banana pulp
Mix the peanut butter with the cream until it is smooth and light in colour, then combine it with the banana pulp and a little lemon-juice and use between thin, buttered slices of bread.
