Dry rub for ribs

A dry rub for ribs needs more sugar than a brisket rub, because the racks are only in the heat for a few hours and you want the surface to brown. This batch is half a cup of packed brown sugar against a quarter cup of Diamond Crystal, with paprika, pepper, garlic, onion, and a teaspoon of mustard powder. The sugar is there to color the ribs on a low pit. A packer sits in the heat all day, so that same sweetness would darken until the bark tastes bitter, which is why the brisket rub leaves the sugar out.

Ingredients

Ingredient	Volume	Weight
Packed light brown sugar	1/2 cup	110 g
Diamond Crystal kosher salt	1/4 cup	34 g
Paprika	2 tablespoons	14 g
Coarse black pepper	2 tablespoons	14 g
Granulated garlic	1 tablespoon	9 g
Onion powder	1 tablespoon	8 g
Mustard powder	1 teaspoon	3 g

Steps

1. Break up the brown sugar with your fingers, then stir in the salt, paprika, pepper, garlic, onion powder, and mustard powder.
2. Peel the membrane off the bone side of each rack and pat the ribs dry.
3. Coat both sides. Two racks should use most of the batch. Leftover rub stays in the jar.
4. Let the racks sit while the pit heats. The sugar will look wet as it draws moisture out. That is normal.

This is a dry rub, not a glaze. Add sauce at the end if you want it, on heat you can watch. Morton kosher salt: use 2 tablespoons plus 1 teaspoon (about 34 g) in place of the Diamond Crystal so the ribs are not too salty.

Why each ingredient

Brown sugar is half a cup, packed, about 110 grams. Ribs cook for a few hours, so the sugar has time to brown and then the cook is over. A packer is a different day. If you pour this rub on one, you'll taste the extra sweetness after it has sat in the heat too long. The brisket rub leaves the sugar out for that reason.

Diamond Crystal is a quarter cup, about 34 grams. Ribs are a thin piece of meat, so they don't need the half-cup salt load of a packer. Morton is a tighter crystal, which means the same scoop is saltier. Use 2 tablespoons plus 1 teaspoon of Morton, about 34 grams, and the ribs stay seasoned instead of tasting like a salt crust.

Paprika, two tablespoons, about 14 grams, is there for color. Coarse pepper, two tablespoons, about 14 grams, is the bite you still taste after a wrap. Granulated garlic and onion powder, a tablespoon each, are the savory base under the sugar. Mustard powder, one teaspoon, about 3 grams, adds a little tang so the sugar doesn't taste flat. If you don't keep mustard powder, skip it. The rub still works.

How to apply it

Pull the membrane first. It's the thin skin on the bone side, and rub slides off it, so the meat underneath never gets seasoned. A paper towel gives you a grip. Pat the meat dry, then coat both sides until the surface looks even. The sugar will turn shiny as it pulls water out of the meat. Give it about twenty minutes while the pit settles. An overnight rest in the fridge is optional. The rub works the same morning you cook.

If you want sauce, put it on at the end over heat you can see. Sauce plus this much sugar, left on for hours, is how ribs go black before the meat is tender.

Storage

The brown sugar clumps in humidity. Keep the jar sealed. If it bricks, break it up before the next racks. Garlic and paprika fade before the salt does, so a batch older than a couple of months will taste mostly like sugar and salt. Mix a fresh one.

Variations

Baby backs use the same rub and less of it, because the racks are smaller. A cayenne pinch is the heat variation. Leaving the sugar out makes it a savory rub, closer to the pork butt rub, and you lose the color this page is for.

A full rib method, including 3-2-1, is not written yet. Until it is, wrap choices are on butcher paper vs foil, and a probe is still worth having if you cook more than ribs the same day. Start at meat thermometers for smoking. The BBQ rub recipes index is the map if you season more than one meat.
