Ingredients

  • 1 kg blueberries fresh or frozen; see notes
  • 500 g granulated or caster(fine) sugar see notes
  • 120 ml lemon juice
  • 600 ml water

Instructions

  • Wash and sort your fruit, discard any stalks etc.
    Put blueberries, sugar, lemon juice and water in a large pan and give it all a good mix.
    1 kg blueberries, 500 g granulated or caster(fine) sugar, 120 ml lemon juice, 600 ml water
  • Put the pan on a low-medium heat and simmer gently, stirring often until the sugar has dissolved.
  • Using stick (immersion) blender, puree the mixture directly in the pan. You don't want the smooth puree but rather thick and lumpy one. You really can't go wrong here.
  • Next, bring the mixture to rolling boil and boil for about 5 minutes.
  • Strain the mixture using fine sieve (you can also line it with a muslin cloth), jelly straining bag (which is what I did), clean tea towel etc.
    ***Quick Tip*** If you like to keep your cordial clear, let the mixture strain on its own and without squeezing or prodding. If you're not fussed you can squeeze every single bit of it (that's what I did in the end once my patience run out) but expect it to be cloudy.
    Once strained, transfer to sterilised bottles. 
    Enjoy diluted with still or sparking water to your liking.

Notes

  • Nutritional information is approximate, per entire amount (1.4ltr) of undiluted cordial and should be treated as a rough guideline only.
  • Feel free to use different berries or a mixture of different types to make this cordial. 
  • See 🛒 Ingredients to make blueberry cordial for more information on possible substitutions. 
  • As long as you sterilise the bottles the cordial should last in the fridge for up to 6 weeks. It's also freezer friendly. For more information see 🥡 Storing blueberry cordial 
This cordial is very forgiving so you can adjust the amount of sugar or swap it for honey/maple syrup if you wanted to but it will affect its shelf-life so just bear that in mind.
Don't forget blueberry syrup is to be diluted so don't get too stressed about the amount of sugar in it in the first place. Enjoy it!
Feel free to swap blueberries for blackberries or use mixed frozen berries, you can experiment here and the results will be delicious.
If you're worried about the cordial spoiling before you can finish it you can halve the ingredients to make smaller batch. Also DO sterilise the bottles to prevent pesky bacteria spoiling your efforts.
If you are not too fussed about how clear your cordial is, you can speed up straining process considerably by squeezing the contents through the muslin, jelly bag or kitchen towel. I lost patience very quickly when using my jelly making kit (photos above), took the bag off the stand and squeezed the rest of the cordial out. Done!
Don't get rid of the pulp, I like it with yogurt and granola or as a spread on a hot buttered toast.
