It's that time of year again!
3-4 lbs corned beef
2 onions, quartered
4 celery stalks, quartered crosswise
1 package pickling spices
1 medium green cabbage, cut into 2" wedges
2 carrots, peeled and cut into 2" pieces
1/2 c. Dijon mustard
2 tbsp. apple cider vinegar
1/4 c. mayonnaise
2 tbsp. capers, roughly chopped, plus 1 tsp brine
2 tbsp. parsley, roughly chopped
Step 1 Place corned beef, onion, celery, and pickling spices into a large pot. Add enough water to cover by 2", season with salt and pepper, and bring to a boil. Reduce heat to low, cover, and simmer until very tender, 3–3 1/2 hours.
Step 2 Meanwhile, whisk dijon mustard and apple cider vinegar in a small bowl and season with salt and pepper. In another bowl, mix mayo, capers, caper brine, and parsley. Season with salt and pepper
Step 3 Add cabbage and carrots and continue to simmer for 45 minutes to 1 hour more, until cabbage is tender. Remove meat, cabbage, and carrots from pot. Slice corned beef and season with more salt and pepper.
Step 4 Serve with both sauces on the side for dipping.
