1. Combine apples, dried plums and apricots, and three cups water in a large pot and bring to a boil. Reduce heat and simmer, covered, for one and a half hours, stirring occasionally, until most of the water cooks off and mixture thickens. Uncover and simmer for another 10 to 15 minutes.
2. Remove from heat and let cool to room temperature. Stir in lemon juice and chia seeds. Chill for at least two hours.
3. Garnish with almonds before serving, if desired.
