Raw tripe seems so good for me. It's like gelatin on steroids for my joints; but I haven't found a way to consume it that I actually enjoy. Mixing it in water into a smoothie is gross. No matter how long I try to grind it there always seems to be a string or two of the stuff that gets stuck half way down my throat.
Today I tried slicing it frozen in my food processor, defrosting it and smothering it in garlic, onions and hot sauce with a little pepper and cilantro. I think it would have been better without the garlic and more onions. The garlic over powered the taste which is kind of bland with a hint of fishiness. I think I'll leave it out next time. It might be better too with lemon juice instead of hot sauce.
It's not the taste that I mind. It's the texture. Even sliced really thin in the food processor it was still next to impossible to chew and had the taste and texture of eating paper.
I have my doubts if early paleo's ate it because it is so tough. It would be impossible to tear off a chunk of tripe from a cow with human teeth and chew it; and would require a very sharp knife to cut it up.
The best way to describe eating raw tripe without actually eating it is to buy a box of raw fish. Throw the fish away and eat the box and that's exactly what it tastes like!
