Notes
Recipe inspired by: United Kingdom
Note 1: Apple variety - If you are using a sweet apple variety, rather than the recommended tart Bramley apples, you’ll want to reduce the sugar to around 1/3. Once the apples are cooked at the next step, taste the mixture and add more sugar if desired.
Note 2: Pre-cooking the apples - The time it takes to break down the apples will depend on how large you have cut the apple cubes; 1cm cubes should take around 5-7 minutes, a little larger may take closer to 10 minutes. The apples will go through a stage where they release water but don’t be alarmed, the mixture will thicken up again within a few minutes. The apple filling is ready for the next step once it’s broken down by around 50% and the mixture is thick.
