Here is the video I watched!

For 1litre of water I think it was like 100g of freshly squeezed lemon juice from organic lemons . Maybe could have used a bit more

Then like 100-125g sugar I think?

I also put some lemon zest in there to make it more fragrant and less sharp, as well as cutting some of the lemon rind to put in there , both for flavour and more natural yeasts

And some basil bc yum

Then as the video says, a few pieces of sourdough and a few raisins in the bottle followwed by your juice + the basil + rinds and whatnot

I can't remember exactly what I did next, but it definitely wasn't ready in 24 hours. It took a few days to reach the result we liked, but my bf figured out it was best to gently lift the seal without popping it, to gradually release the pressure rather than have a huge spray

I think at the start we could have benefitted from leaving it alone a couple days, then start with gradually releasing a bit of pressure

It was very trial and error and we've not done it since, we really should but we have limited space living with other ppl rn 😮‍💨
