Multicooker Directions: In Step 1, transfer the browned beef to the inner pot of a 6-quart multicooker. In Step 2, pour the boiling wine mixture over the beef in the pot. Stir the stock, onion halves, garlic, and jalapeño into the pot. Lock the lid; turn Pressure Valve to "Venting." Cook on SLOW COOK [Normal] until the beef is very tender, about 8 hours. Turn off the cooker. In Step 3, remove and discard the onions; transfer the beef to a large bowl. Shred the beef as in Step 3; return to the pot. Stir in the cabbage, salt, and pepper. With the lid off, press SAUTÉ [Normal]; cook, uncovered, just until the cabbage wilts. Finish Step 3.
