These berries are difficult to find fresh but can be bought in freeze dried tablet form and can make for an interesting tasting experience.
I decided to pick up a pack and tried them with my family. We set up a series of things to taste: fruit juice, vinegars, wine and some citrus fruits.
It takes a bit to dissolve the tablet on your tongue but I have to say it was an interesting experience. All of a sudden a clementine tasted like candy and I could sip a little vinegar without any trouble.
You have to be careful with these tablets though. You are still drinking acidic things and while your tongue may not mind, your stomach certainly will.
If there was a cheaper way to market this product, I think it could be an inventive way to help people with diabetes reduce their sugar intake. The tablets are certainly on the pricy side.
If nothing else this is a fun little experiment for the foodies in your home. Maybe give them a try at your next party. Be sure to eat dinner first though since the effects last as long as 60 minutes.
