What are St. Louis Style Ribs?

What are St. Louis style ribs?

St. Louis style ribs are a type of sparerib. Spareribs consist of the section of the rib cage between baby back ribs and the pig’s sternum. Full spareribs include rib bones, cartilage, the rib tips, and even part of the sternum itself. St. Louis style ribs are spareribs that have been trimmed down to a more uniform rectangular shape, with the sternum, cartilage, and rib tips removed.diagram showing st louis ribs on a pig

What is the difference between St. Louis style ribs and baby back ribs?

St. Louis style ribs consist of the portion of the rib cage closer to the pig’s belly, while baby back ribs are closest to the pig’s spine. St. Louis style ribs have longer, flatter bones than baby back ribs, which are shorter and more curved. The meat on St. Louis style ribs is very fatty and lies mostly between the rib bones, while baby back ribs are somewhat leaner, with most of the meat sitting on top of the rib bones.

Prep the Ribs

Most spareribs that you find in grocery stores have already been cut in the St. Louis style. If the packaging doesn’t say “St. Louis style” you should be able to tell based on the very symmetrical, rectangular shape of the ribs. If you have full spareribs, you’ll need to start by trimming away the breastbone, rib tips, and squaring off the rack before you’re left with a St. Louis style cut. The folks over at Serious Eats have a great walk-through of the process.

Once you’re working with a St. Louis style cut, there are still a couple preparation tasks you need to do. First, remove the membrane from the back of the ribs. This is the thin but tough, translucent white layer found covering about half of one side of the ribs. Use a dull knife or your fingers to get a corner of the membrane peeled away from the ribs. Then, using a paper towel for grip, you should be able to pull the rest of the membrane off in one go. This membrane is naturally tough, and won’t render down as well during the cook. Removing this ensures a clean, tender bite through on your finished ribs.

Next, do any clean up trimming needed to make a clean, uniform rack of ribs. This includes removing any small dangling pieces of meat or fat that may dry out during the cook. You may also need to remove the diagonal flap of meat that is part of the pig’s diaphragm. You’ll find this on the same side of the ribs as the membran you just removed. Lastly, square off the ends of your rack if necessary, by removing the small ribs on the end. SAVE ALL THESE TRIMMINGS! This is good meat that you can include in a number of other dishes, including baked beans and sausage filling.

Season the Ribs

Now it’s time to put our first layer of flavor on the ribs. Make sure they are dry of any moisture if you haven’t already. Starting with the backside, apply a thin layer of binder. This can be olive oil, hot sauce, or mustard, and it will help the dry rub stick to the meat. Don’t worry too much about the flavor here – you won’t really be able to taste it after 5-6 hours in the BBQ. Next, sprinkle a liberal and even amount of your favorite dry seasoning onto the ribs, and gently rub it in to make sure it sticks. Check out some of our favorite pork rib rub recommendations below, or our list of the Top 15 BBQ Dry Rubs.

Alternatively, you can use a simple mix consisting of a 3:3:1 ratio of kosher salt, black pepper, and paprika.

BBQ the Ribs

The prep work is done and it’s time to put these bad boys on the barbecue! We’re going to be using a 3 stage approach for these ribs – smoke, wrap, and sauce. The first stage is going to infuse the ribs with awesome smoke flavor, and a beautiful mahogany color. The second stage is where we’ll get the ribs up to an internal temperature where the connective tissues start to render down, giving us perfectly tender ribs. In the last stage we’ll sauce the ribs, applying our final layer of flavor and getting a beautiful tacky finished texture.

Smoke

Get your smoker or BBQ running around 225 degrees, and loaded up with your favorite hickory wood logs, chunks or pellets. Our goal in this stage is low and slow, bathing the ribs in maximum smoke. Place the ribs in your smoker or BBQ in a single layer and over indirect heat. Let these hang out for 3 hours, spritzing about every half hour with apple cider vinegar or apple juice if the surface starts looking dry. Other than that, keep your BBQ closed to make sure all that beautiful smoke stays inside – if you’re lookin’ you ain’t cookin’!
