Slow-cooked brisket finished 5 minutes under the broiler with a brown sugar and mustard glaze.

### Ingredients

- 3 to 4 lb corned beef brisket flat
- 1 spice packet
- 1 yellow onion, sliced
- 2 cups beef broth
- 2 bay leaves
- 1/4 cup brown sugar
- 3 tbsp whole grain mustard
- 1 tbsp apple cider vinegar
- 1/4 tsp ground cloves
- 1/2 tsp black pepper

### Directions

- Rinse the brisket and pat it dry.
- Spread the onion in the crockpot and set the brisket on top.
- Pour in the broth with the spice packet and bay leaves.
- Cover and cook on LOW 8 to 9 hours, until the thickest part reads 190 to 205°F.
- Heat the broiler with the rack 6 inches from the element.
- Lift the brisket to a foil-lined sheet pan.
- Mix the sugar, mustard, vinegar and cloves into a paste.
- Spread the glaze over the fat side.
- Broil 3 to 5 minutes until the glaze bubbles and darkens.
- Rest 15 minutes, then slice across the grain.

 

### Notes

 

Glaze burns fast, so stay with it. Do not glaze at the start of the cook, because it will wash into the liquid.

 

  

## Why the glaze goes on late

 

Corned beef cooks in a salty, spiced liquid for hours, and the glaze is only a quick finish. Brown sugar and mustard caramelize under the broiler in minutes, giving a sweet and tangy crust on the outside of the meat.

 

Whole grain mustard keeps a little texture and bite.

 

## Swaps that work

 

Dijon is fine if you do not have whole grain mustard. Maple syrup can replace some of the brown sugar. Do not glaze before the cook, since the sugar will melt into the liquid and the topping will not set.

 

## What goes with it

 

Roasted potatoes and cabbage are the classic partners. Warm rye bread and a little extra mustard on the side also work well.

 

## The mistake to avoid

 

Walking away from the broiler. Sugar goes from golden to burnt in under a minute, so stand there and watch.

 

Pat the cooked brisket dry before glazing so the sugar sticks. Slice across the grain after a short rest, and the slices will hold their shape under the topping.
