Kitchen chemistry - sodium citrate
Today I wanted to make cheese slices à la Heston Blumenthal that he used in his perfect hamburger recipe. Problem was that I had no sodium citrate laying around. What to do on a sunday morning when all shops are closed? Call your chemist buddy of course. After a few text messages and a quick call I was ready to make my own sodium citrate. Dead simple really:
- 19,2 g citric acid, dissolved in 200ml water at 25C
- 25,2 g sodium bicarbonate (baking soda), dissolved in 200ml water at 25C
Pour the sodium bicarbonate into the citric acid until the reaction stops (it fizzes like crazy)
Then you'll have 400ml sodium citrate solution. 16g solidified sodium citrate = 250 ml
