The cured pork meat and fat sausages above—a type of thin salchichón called fuet in Catalonia, Spain—are truly delicious, with a wonderfully intense umami flavour. They are also excellent for your health, as good as having a yoghurt, because they are full of probiotics: probiotics that are found in baby poop.
I know, you're grossed out now, but the fact is that they are delicious because they taste just like regular fuet. There's really no difference in flavour. It's all about bacterias, which are responsible for developing many of the flavours you love in meat, fish, vegetables and cheese, by breaking out proteins and other elements, creating new compounds that our taste buds find delectable.
The only difference between these and regular fuet is that the latter uses the bacteria naturally present in animal flesh to develop its distinct flavour, like any other other cured meat. The fuet sausages above, however, use bacteria from the microbes found in baby poop, which is rich in two probiotics: Lactobacillus and Bifidobacterium.
According to scientists at the Catalonia's Institute of Food and Agricultural Research—who took the bacterium from 43 faecal samples of kids up to six months old—"infant faeces are natural samples, easy to obtain." According to Anna Jofré, one of the researchers who made them:
Probiotic fermented sausages will give an opportunity to consumers who don't take dairy products the possibility to include probiotic foods to their diet.
She also told LiveScience that they ate them "and they tasted very good".
