However – I did not manage to make the glaze work – I tried three times t melt the brown sugar and butter, but each time the sugar just burned instead of melting, and the butter floated on top – this happened regardless of whether I stirred, swivelledd or left the pan alone. I used a medium heat, as you say in the recipe – can you give me any pointers for cucceeding with getting the butter and brown sugar to combine so that I get a butterscotch glaze rather than hot cream with burnt brown sugar crystals?
