Step 1

To prepare brisket: Combine paprika, salt, garlic powder, onion powder and pepper in a small bowl. Rub all over brisket. Heat oil in a large, heavy skillet over medium heat. Add the brisket and brown on both sides, 3 to 5 minutes per side. Transfer to a 6-quart slow cooker.

Step 2

Add beer (or broth) to the pan along with any remaining spice blend from your cutting board; increase heat to high. Cook for 5 minutes, scraping up browned bits with a wooden spoon. Pour over the brisket. Cover and cook on High for 6 hours or Low for 9 hours.

Step 3

To prepare pickles: Meanwhile, combine white vinegar, cider vinegar and brown sugar in a small saucepan; bring to a boil over high heat and cook for 1 minute. Add pickling spice and 1 teaspoon salt. Pour into a large, heatproof glass bowl and add cucumbers and onion. Refrigerate, stirring occasionally, for at least 1 hour or until ready to serve.

Step 4

To prepare garlic mayo: Mash garlic and 1/2 teaspoon salt into a paste in a mortar and pestle or with the back of a spoon on a cutting board. Combine the garlic mixture with mayonnaise in a small bowl. Cover and refrigerate until ready to serve.

Step 5

When the brisket is done, transfer to a clean cutting board and let rest for 10 minutes.

Step 6

Pull the brisket apart into shreds with 2 forks and then coarsely chop the shredded meat. Combine the chopped brisket with the liquid in the slow cooker.

Step 7

To serve, drain the pickled vegetables. Spread each bun with 1 tablespoon garlic mayo and top with about 3/4 cup brisket and 1/2 cup pickles.
