🥩 What is Pork Tenderloin?

Before we dive into the recipe, let’s clear up a common confusion:

Pork tenderloin is not the same as pork loin.

  • Pork tenderloin is a thin, long cut of meat from along the pig’s backbone. It’s extremely tender because this muscle doesn’t get much use.
  • Pork loin, on the other hand, is wider, thicker, and requires longer cooking methods to become tender.

Most store packages contain two pork tenderloins, each weighing about 1–1.5 pounds. Both are used in this recipe.


💧 The Secret to Juicy Pork: Brining

Brining is the key to keeping pork tenderloin juicy, even if slightly overcooked. It only takes 20 minutes, and it makes a huge difference.

Why Brine Works:

  • It hydrates the meat through osmosis.
  • It relaxes muscle fibers, helping them retain moisture during cooking.
  • It brings the meat to room temperature so it cooks more evenly.

Basic Brine Ingredients:

  • Warm water
  • Salt
  • Brown sugar
  • Vinegar
  • Ice

Soak the pork for just 20 minutes—no more, or it could turn mealy. Then rinse and pat it dry.


🌶️ Flavor-Packed Wet Rub

Instead of marinating, this recipe uses a wet rub—a blend of spices and oil that sticks to the pork and delivers big flavor.

Ingredients in the Wet Rub:

  • Olive oil
  • Lime juice
  • Paprika
  • Garlic powder
  • Onion powder
  • Brown sugar
  • Ground cumin
  • Chili powder
  • Ancho chili powder
  • Salt and pepper

This combination creates a smoky, sweet, and earthy crust that caramelizes beautifully on the grill.
