While allowing the compote to cool down, sift the flour and add the sugar in a mixing bowl and fold them together. Add the butter pieces. Using your hands, pinch the flour (with sugar) and the butter pieces together to mix and combine them. Continue doing this until a buttery, crumbly mixture is made. Shake the mixing bowl to allow any bigger mixture chunks to get to the top, and then pinch these to break them apart and make them smaller. Mix in the cinnamon.
