.....................am wondering about doing my own equivalent ie adding lemon s etc to plain water any ideas how to. .....................
I've been doing something like this for some time.I use a jug with a capacity of around two pints. Get one lemon, peel it, segment it and look for (and extract if seen) pips. Put lemon segments into jug add about .75 pints water and whizz up with soup whizz wand ( what ever the proper name is ) This needs a bit of care as the wand may clog with pulp that needs to be cleared from time to time. When you are happy with wand work you may want to dilute a bit more ( depends on your taste and size of lemon 🙂 ). Add sweetner to taste.
Note that despite lemons being sour they are far from free of sugars
Good Luck

P.S. Dont try this with grapefruit without first reading PILs for any drugs that you are one
