Heat berries in a pot on the stove on low heat, stirring constantly. Once they start to warm up, use a vegetable masher to mush them all up. They should turn pretty juicy within a few minutes. Remove from heat once they are all juice and seeds.
Add honey, mix, and let cool for a few minutes.
Add chia seeds and mix well.
Pour into a jam jar or airtight container. Once jam has cooled to room temperature, chill in the fridge for about an hour to set.
Will keep in the fridge for up to a week.
