For the baked apple sorbet, wash and dry apples and score the top a bit to allow some moisture to escape. Brush with sunflower oil or egg white and roll in granulated sugar. Place on a baking tray and roast in a preheated oven at 220°C for about 25-30 minutes. Let them cool down a bit and press them through a strainer. Season with a little cinnamon and possibly a little rum or apple brandy.
Freeze in an ice cream maker or in the freezer (stirring frequently or blending with a hand blender) for about 1 hour. If the sorbet is too thick or frozen too hard, add a little apple juice or lauter sugar (sugar and water boiled 1:1 and cooled) and blend again. Arrange the baked apple sorbet in narrow glasses or strudel tulips, preferably with the help of a piping bag.
