tl;dr it's great in tea, hot chocolate, and covers the posassium citrate taste in my home-brew electrolyte drink, cheaply and efficiently. It's perfect for what it does.
It adds a pleasant flavor to water that covers the "tap water" taste or even the taste left over after the water has been through a Brita filter. You can also make limeade with it, or flavor tea or hot chocolate. More importantly, because this is what I bought it for, it covers the taste of potassium citrate.
One packet in an 8oz glass of water or a 16oz water bottle seems to do it for me as a flavor enhancer.
1/2 packet in a 11oz tea or hot chocolate is plenty. If you are not familiar with the joys of lime hot chocolate, you need to give it a go.
Takes a lot to make a glass of limeade: I use 6 packets and 3 tablespoons of raw sugar. But that's still just $0.42 vs $1 for a lime (plus the extra work).
And it makes a good vodka and lime.
I have water with a half teaspoon of potassium citrate twice a day. That normally has a taste that is best described as "strange", sort of like diluted milk. My normal solution, "just add tea" doesn't work. You cannot potassium citrate with tea: they react and form something that tastes horrible. I should have realized that they wouldn't mix, because potassium citrate can be used to clean stains on teacups.
Fresh lemon tastes great with potassium citrate, but a good glass of lemonade is expensive: $1 for the lemon, plus the sugar, plus the work. So I looked into "flavor enhancers". This was actually one of the first I tried, but reviewing it sort of ended in the back of my mind when I ended up doing reviews of the products that failed.
Anyway, this stuff rocks. I'm going to try the other flavors.
Crystallized Lime [citric acid*, lime oil, lime juice].
