First of all, you have to consider how many people you have to support. My experience is that each person has one rib, so if I have four people, I will find a 4-bone rib, which is a common size in supermarket refrigerators. If you want seven complete ribs, you may have to ask the butcher, but they usually don't object.

(Excerpted from my cookbook)

First of all, I want to see the grade of beef. Most standard North American supermarkets will supply USDA/Canadian AAA beef, which is ok, but I usually look for high quality or better beef. The best and better will cost you $ $ $,because only 2% of all processed beef in North America is the best and better, and you are more likely to buy it in a butcher shop or a high-end supermarket. But as long as you know what you are cooking ribs, CHOICE/AAA is absolutely suitable for families, and you can buy it at a reasonable price. Next, look at the beef itself. The beef you want is good, red and fat looks like white milk.

What kind of fat do you want? Ideally, there should be a considerable number of marbles. If you look at the picture above, you can see that there are more fat marbles in high-quality meat than those in /AAA, but there is still a lot of extra fat. In any case, you don't want large chunks of fat to be cut off. Next is the problem of aging. What's more, the meat in the supermarket was wet cooked within 14 days. Old jerky will be much more expensive, but it tastes better. It all depends on you and your budget. If you are willing to spend two or three times the money, dry baking is a very enjoyable thing.

Alternatively, if you have time and use a vacuum sealing machine, please select some UMAI dry aging bags and dry age them at home for at least 2 1 to 30 days. This is much cheaper than buying cooked meat from a butcher. I just want to tell you that if you decide to try this, you have never cooked beef before, and you will lose some beef because it will have to be reduced. I have a small bone barbecue in the refrigerator that has been air-dried for 4 months, and I plan to enjoy it on New Year's Eve. ...

The prime rib is a very delicious food. I cook it myself twice a year (although I do eat a lot of steaks and occasionally eat some buffets). But because I seldom do this, I deliberately made it an elaborate thing. It's a small job, but it's worth spending time with family and friends ... or just me once in a while, because my wife is not at home and no one is watching me around.
