If you are lucky enough to live in the U.K., you can get it in the form of innocuous pre-processed pellets . I do not live in the U.K.
So, when we bought half a cow recently, I asked the butcher for the suet. He asked what that was, and then said that they call it the leaf fat. He brought out a great big chunk to the yard, hacked off the meaty tendony bits into the Trash Can O' Animal Bits, wrapped it up for me, and said I could come back any time for the same. Usually they use it to mix into ground game meats.
Let's do this.
7:00 a.m- Looked at leaf fat. Resolved to make it into suet today.
8:00- Looked at leaf fat. Resolved to make it into suet soon.
9:00- Looked at leaf fat. Resolved to make it into suet soon.
10:00- Looked at leaf fat. Resolved to make it into suet soon.
11:00- Looked at leaf fat. Resolved to make it into suet soon.
12:00 p.m.- Convinced husband to cut it into chunks. Cut one chunk myself. Had severe hibbity jibbities. Vowed never to do it again. Husband asked if this was going to smell weird. I reassured him that it probably wouldn't. Possibly. Anyway, it'd probably just smell like beef.
12:15- Put it in the crock pot, with about 2 cups of water.
3:07- Does it smell weird in here? Not super weird, just a little weird?
3:11- It smells weird in here. Is it the suet? It is, isn't it. I should check.
4:00 Lifted the lid of the crock pot. IT IS THE SUET. It does not smell like beef. It smells like fish that has gone off. I hope this doesn't get worse. It isn't too bad as long as you don't open the lid.
4:46- Put crock pot in garage, to quench the smell of death.
5:54- I think it is following me. No. It's just residual.
7:01- suspect stench is infiltrating. Told Husband I was pulling the plug on this project, but he convinced me to try it just a while longer. Sigh.
8:27- The stench may be lessening... or I am just getting used to it.
10:09 p.m., next day- Fat still not entirely rendered. This is taking much longer than I thought it was going to. It doesn't stink anymore! Hooray!
1:43 p.m., the day after that- Looks like pineapple chunks in syrup. Smells... like beef! Admittedly not a super quality in something whose purpose is to go into desserts, but much better than Nasty Fish flavored.
1:48 p.m.: I'm tired of this. I'm straining it.
This is after chilling. Creamy and delicious? I guess?
Now, to do stuff with it! Yay.
As a reward for getting through all those icky pictures:
