A melon baller makes a great pear corer – halve your ripe pears and use it to scoop out the seeded bit from the core. If you don’t have a melon baller, a teaspoon will do.
Arrange the pear halves on a baking tray lined with baking parchment. Brush with the melted butter and sprinkle with the 1 tablespoon of caster (superfine) sugar.
