Make your own DIY Health Salts. The perfect antidote to "overindulgence".

Don't make too much of the combined powder at once, as it is prone to moisture absorption and clumping. If the Epsom salts are damp they will need dried before mixing in with the other ingredients. The best results are obtained from mixing the drink ingredients on demand.

There's an even easier recipe for a nice tart zero sugar version that only has two ingredients added separately on demand. Just half a level teaspoon of citric acid and half a level teaspoon of bicarbonate of soda. I recommend using a proper half-teaspoon measuring scoop and making sure it's level.

In the UK you can buy an effervescent powder which has had various names in the past, including Liver salts and Health salts.
The powder dates back to the 1890's when it was sold as a medicinal compound to promote "inner cleanliness", and even now it is sold as a remedy for "symptoms of over-indulgence".

In use, a teaspoon of the medicinal powder is put into a glass of water and stirred thoroughly, whereupon it erupts into a fizzy drink. The taste is slightly sweet and salty. It's quite pleasant actually.

With happy memories of drinking it as a kid, I bought a tub of it recently and was surprised to see that the ingredients are really just household items. In fact, it's just one ingredient more than children's sherbet powder.

So I decided to make some....
