Mix the apple cubes, cinnamon and raisin together and set aside.
Heat sugar in a pan until it caramelises and add in butter cautiously as the hot mixture may splatter.
Cook the apple in the pan and add in the thickened corn flour mixture. Once cooked, set aside.
Pre-heat oven to 160°C using the fan mode or 4D Hot Air program on the Bosch Combi-steam oven.
With the Bosch MaxxiMUM Kitchen Machine, mix butter, sugar, almond and flour in this exact order until the mixture is homogenous.
