Gat-kimchi (Mustard Leaf Kimchi)
A boldly flavored kimchi in which the sharp, mustard-like bite of fresh gat (green mustard leaves) tingles the nose. A cooked flour paste is stirred into a gochugaru seasoning, brined mustard greens are folded in, and an overnight rest brings out a clean, pungent, deeply savory kimchi.

Directions
- 1

In a large basin, dissolve 4 cups of salt in 8 cups of water to make a strong brine. Since the greens won't sit for long, keep the brine on the saltier side.

Trim the mustard greens, submerge them in the brine, and toss to coat evenly. After 1 hour, turn them over and brine for 1 more hour. Once softened, rinse several times in clean water and drain.

In a pot, whisk 2 cups of flour into 8 cups of water and cook, stirring gently so no lumps form, until it thickens into a paste. Let it cool completely.

To the cooled flour paste, add the red chili powder, fish sauce, plum syrup, minced garlic, sugar, and sweetener, and mix well into a seasoning. Because the greens are already fragrant, add just 5 tablespoons of garlic.

As the seasoning comes together, it takes on an appetizing deep-red color from the chili powder.

Add the brined mustard greens to the seasoning and toss thoroughly along the stems, then finish with 2 tablespoons of sesame salt.

Five bunches of mustard greens make a generous batch — plenty for the whole family to enjoy over time.

Pack the finished gat-kimchi into a container, ripen it overnight at room temperature, then store it in the refrigerator.
Tips
There's no single right way to make kimchi — the flavor shifts with the water, fish sauce, and salt you use. After brining and rinsing the greens, taste them and adjust the seasoning to your liking.
