Today I’m making what many people have called the best grilled cheese recipe in the world – Borough Market’s Grilled Cheese Toastie from Kappacasein on Stoney Street, London!

This legendary London cheese shop is known around the globe for their toasted cheese sandwiches, made with a mixture of Ogleshield raclette, Comte (a French Gruyere) and aged English cheddar cheese. But what makes this Cheese Toastie really unique is its filling of five different types of chopped onions!
