Space Pantry Sour Keys

Acids like citric acid and tartaric acid are commonly used in sour candy recipes. Acid yields hydrogen ions when they come into contact with saliva in our mouths. These hydrogen ions stimulate specific taste bud receptors on our tongues, triggering a sour taste sensation.

Fun Fact: One of the main benefits of freeze-dried candy is that it can last much longer than the original candy, but how long depends on how you store it. In ideal conditions, freeze-dried food has been known to last for 25 years or longer.
