We know from our parents that eating pineapple with salt makes the pineapple seem sweeter and a few years ago we saw Heston's Feasts (or one of his shows) where he challenged done villagers to see who had the tastiest hot chocolate he won. It was revealed that his killer ingredient was salt.
We wanted to test if Heston won because it's his tv show and not winning on one's own show would be a bit silly, or if salt does actually make the hot chocolate taste nicer. Earlier in the week we made 1 cup with salt and it seemed better but we needed a blind test to confirm.
Hypothesis: Does salt make hot chocolate tastier
- 2 cups one with a half pinch of salt (not to self, next time use 1/4 pinch of salt if splitting one cup of chocolate)
- Make 1 cup of Koko Black cocoa (3 heaped teaspoons of Koko Black cocoa powder and 1/2 cup of milk frothed together)
- Pour half the cocoa mixture into each cup
- Taster was asked to taste both cups and say which was tastier
The tester who drinks the Koko Black every morning could tell which one was which and noticed the salted one was too salty (they also were the experimenter so their opinion is void).
So with one test subject this isn't statistically valid but Heston only had 6 tasters so meh...
The unsalted cup was deemed "flat" and "watery" and the salted cup was deemed more flavoursome. This is despite the mixture being exactly the same aside that a tiny bit of salt was added to one cup before pouring.
The hypothesis that salt enhances the flavour of hot chocolate is supported.
