I regularly boil whole skinless chickens then debone them and freeze the meat. I end up with about 4 qts of weak broth. For a long time I’ve been boiling it down to one quart but those containers were building up in my freezer, as I haven’t been eating enough soups. So today, with time on my hands I decided to go all the way… oh yeah, we’re talking meat extract. I wanted it thick and pasty like bovril.
I got down to about 4 oz and it was still very thin but I decided to stop there. I knew it would gel up when cold. It was pretty dark by that point, like a dark caramel flavor. The flavor? Intense! And yummy! I added nothing to the water when cooking the chicken but it had a salty flavor! There was also a sour-ish quality which surprised me, and then finished with like the crispy roasted flavor. Good stuff! I poured it into a little jar and plan to use it for flavoring ramen instead of the powder packet.
Regarding the saltiness I remember learning in my zoology classes in college (my major) that herbivores crave salt (you have to give it to livestock) because they don’t get it in plants but carnivores get salt from their diet of meat and that’s one of the reasons you have to be careful about not giving cats salted meat because their kidneys are already on overdrive from protein and natural salts in meat.
