I'd say, eat whatever organ meats taste good to you. There's no point force-feeding yourself offal if you can't stomach it. Could you really eat something you hated, frequently, for the rest of your life? I've cooked liver several times and have always been utterly revolted.

That's not to say you can't get used to a food you don't currently care for- but I personally can't get over my aversion to liver.

To make up for it, I order liverwurst online from US Wellness Meats, and it tastes great (similar in taste to deli roast beef IMO). It's pricey, but I felt it was worth getting since it's chock-full of vitamins and minerals. It's part beef trim, liver, kidney, and heart.

Sweetbreads are yummy and not gross at all. They are delicious and easy to prepare: just poach in stock and then fry in tallow or lard.

Try oxtails. They aren't technically organ meat as they're just the tails of the cow. But there are lots of bones and if you slow cook them you get a lot of the benefits of bone broth, like gelatin, without the blandness of real bone broth and with some actual meat you can eat.

Hearts, tongue, and liver are what I consume regularly.

The trick for heart and liver is to not over cook them. Overcooking heart makes it very tough and destroys all the taurine in it. Liver takes on a very nasty smell.

I use this recipe and make a pate out of both: http://farmlet.co.nz/?p=199 I soak the liver in water, which I change a few times before cooking it - this seems to get rid of the smell. Also remove any silver skin off it before cooking as these tend to be stringy. Again, just lightly cook the heart and liver chunks, just for about a minute or two.

The result is very creamy, has an almost cheese like flavor. I then take this and place it in a pyrex bowl, cover it with cracked pepper and let it cool, then place it in the freezer. I then hack off a chunk of it and put it in my lunch, which is usually a salad. Since it's frozen, it helps keep the salad fresh, and by the time I eat it, it's melted and ready.

Tongue you can make the same way as corned beef, but remove the skin after it's cooked. As per Cordain tongue is similar in nutrients to brain, and these days there's a fear of CJD from brain tissue, so if you have it, make sure it's not beef, sheep, or other animals that are susceptible to it. I tend to avoid beef ox tails for the same reason since they do contain some nerve tissue. (I get most of the organ meats from Bison which seems to avoid the whole issue.)

While not organs, beef tendons are awesome when making a brother - add them in towards the end unless you want them to dissolve.

I can't seem to bear liver either. I got a whole cow liver when my beef was slaughtered last year. You can cut it into TINY pieces and freeze it raw (or cooked I suppose..I just do raw) then you can "take" a couple/few chunks a day like pills.

Along with my nasty ass FCLO. Better than nothing!

Have you tried liver with bacon and onions? Chop the bacon, get it going and when the fat starts to render, add the onions. Once they are translucent and starting to caramelize, add the liver and sear for 2 - 3 minutes on each side. DELICIOUS.

The pork fat helps the taste for those who aren't crazy about it. This is how my mom got my brother and I to eat liver for years without realizing it wasn't just a really creamy steak. :)

eat a variety of organs. i prefer beef to pork and chicken, but i have had little opportunity to try lamb.

Chicken hearts are amazing.

You should be eating liver even if you don't like the taste. Man up and just eat it one liver meal every other week. If you don't like pate, I don't really know of any other way to fully mask the liver taste.

Personally, I love chicken hearts and gizzards. I just bake them in a shallow pan at 300 for 30 minutes, then smother them in butter, salt, and pepper. I eat other bird hearts and gizzards the same way. I don't like liver, unless it's in pate. MDA had a duck liver pate recipe that I will try.

Which ones? "All of them."
