Add berries, honey, and lemon juice to a small saucepan over medium heat.
Stir frequently and simmer for 5–7 minutes, until the berries break down and the mixture becomes juicy.
Use a fork or potato masher to mash the berries (leave some chunks for texture if you like).
Remove from heat and stir in the chia seeds.
Let sit for 10 minutes to thicken, then transfer to a clean jar and store in the fridge.
