I like to drink squash but it always comes in plastic bottles. I’ve been saving those plastic bottles for a few months before making a load of elderflower cordial. It’s the first year of doing it at scale (hope to make in all 20 litres) but it’s great to go foraging. Check out a few of the photos.
It should do us for half the year of more and then we can reuse the bottles again! Have a similar system going with jam…
Good recipe here to follow although I do it slightly differently. Happy to give tips!
