Soak the dates for up to an hour (if using softer dates, like medjool, they may not need soaking)
Pre heat the oven to 200ºC
Add the self raising flour, cinnamon, and salt into a large mixing bowl.
Strain the dates, reserving the date water. Blend the dates with 1/2 cup of the date water and add it to the mixing bowl. Then add the vanilla extract, apple sauce and lemon rind. Add in the sparkling water and mix well. Lastly add the blueberries and mix gently through.
Fill a muffin tin with patty pans. Spoon the mixture evenly between the pans.
Bake at 200ºC for 20 to 25 mins or until a skewer comes out clean. Enjoy!
