Add lemon. Stir in the lemon juice and return the pan to the heat. Bring to a brief boil, then remove from heat.
Thicken. Stir in the chia seeds and honey until evenly combined.
Cool and set. Let cool, then transfer to an airtight container and refrigerate for at least 4 hours until fully thickened.
