Peel and core the apples, then roughly dice them. Place in a saucepan with roughly 125 ml of water, 50 grams sugar, 1 cinnamon stick, and 1 tablespoon lemon juice. Bring to a boil over medium-high heat, then reduce to medium and simmer for 10-15 minutes until very soft. Remove from heat and let cool to room temperature, about 15-20 minutes.
Remove the cinnamon stick and puree the apples with a hand blender until smooth.
Beat the cream with a hand mixer for 3-5 minutes until stiff peaks form.
Carefully fold the applesauce into the whipped cream, divide into 4 bowls, and decorate with sliced almonds, a pinch of cinnamon, and some lemon balm.
