Preheat the oven to 180°C (350°F/Gas 4) and line a baking tray with baking paper. Remove the crusts from the bread and cut it in half horizontally to give two layers (if your loaf is extra high, you can make three layers). Put the pieces on the tray.
Mix the butter, honey, sugar and pecans to get a gooey mixture. Pour and spread over the tops of the two bread halves. Bake for about 30 minutes, until the bread is crusty and golden on top (don’t burn it or the nuts will be bitter). Let it cool a dash, then cut into thick fingers. It will crisp up and become crunchier.
