How to Make It
Combine first 10 ingredients in a Dutch oven over high heat. Cook 8 minutes or until salt and sugar dissolve, stirring occasionally; remove from heat. Cool completely. Place beef in brine; cover and refrigerate overnight.
Remove beef from brine; pat dry. Refrigerate, uncovered, 6 to 24 hours or until dry and tacky.
Heat a large enameled cast-iron Dutch oven over medium heat. Add 3 tablespoons oil; swirl to coat. Season beef with pepper. Place half of beef in pan; cook 15 minutes, turning to brown on all sides. Remove from pan. Discard oil. Repeat procedure with remaining 3 tablespoons oil and beef, reserving 1 tablespoon oil in pan.
Preheat oven to 325°. Add onion, celery, carrot, and grated garlic cloves to pan; cook 15 minutes, stirring frequently to scrape up browned bits. Add tomato paste and anchovies; cook 5 minutes, stirring frequently. Add oregano and paprika; cook 1 minute. Add wine, vinegar, and agave; simmer 10 minutes or until liquid is almost gone. Add stock; bring to a simmer.
Return beef to pan. Spoon vegetables over beef; simmer 5 minutes. Cover and braise at 325° for 3 hours, basting every 30 minutes.
Remove beef from pan. Cool liquid slightly; skim and discard fat from surface of liquid. Remove meat from bones; discard bones. Cut beef across the grain into slices. Bring vegetable mixture to a boil over medium-high heat; reduce heat, and simmer until reduced to 3 cups or until slightly thickened, stirring frequently. Return beef to pan. Refrigerate overnight, or serve immediately.
Combine parsley, rind, and garlic. Sprinkle over beef.
