Add the frozen raspberries and water to a pan over medium heat. Use the back of a spoon to help break up the raspberries. Add the honey and stir to combine.
After a couple minutes the raspberries will start to boil. Let the raspberries continue to boil until the mixture has thickened to a runny jam, about 5 minutes.
Turn off the heat and add the chia seeds. Stir until the chia seeds are well distributed. Carefully transfer the jam into a glass jar. Cover and transfer to the fridge to cool completely.
Once the jam is cooled, it should be thick and ready to eat. Enjoy!
