1. Rinse the strawberries well and remove their stems. Finely chop the strawberries and place them in a pot. Pour the honey over them and let them sit for a while to release their juices.
2. Next, lightly mash them with a spoon, add the lemon juice and zest, and place them on the heat to boil. Boil for 10 minutes, then add the chia seeds and stir. Let it simmer until it thickens, about 15 minutes.
3. Finally, add the vanilla. Let it cool. It will thicken further as the temperature drops. Transfer it to sterilized jars and store it in the refrigerator.
