Place all ingredients in a saucepan with 80 ml of water and stir over medium heat until the mixture starts boiling.
Place a lid on the saucepan and reduce the heat to cook the apples for 10-15 minutes until soft.Stir occasionally and make sure there is always a small amount of liquid or juice in the saucepan.
When the apples are soft enough, use a fork or a masher and coarsely mash the apple cubes.
Notes
Cinnamon is a must with the apples, but not only, vanilla bean, allspice, nutmeg, ginger are also great choices.
The lemon juice prevents the natural apple oxidation.
The amount of sugar depends on the sweetness of the apples.
