This is a classic, refreshing banchan (side dish) that perfectly balances the earthy, slightly bitter taste of the acorn jelly with a savory, spicy, and nutty dressing.
- Prep time: 10 minutes
- Cooking time: 0 minutes (if using ready-made mook)
- Servings: 2–4 as a side dish
🛒 Ingredients
The Base:
- 1 pack (about 10–12 oz) Acorn Jelly (Mook) – sliced into bite-sized, wavy, or rectangular pieces
- 1–2 cups Lettuce (red leaf or green leaf lettuce), torn into bite-sized pieces
The Dressing:
- 1.5 tbsp Tuna Sauce (or substitute with standard Korean fish sauce)
- 1 tbsp Gochugaru (Korean red pepper flakes) – adjust to taste
- 1 clove Garlic, finely minced
- 1 tbsp Sesame Seeds, toasted (plus extra for garnish)
- A pinch of MSG (the secret to that authentic restaurant-style umami)
- Optional: 1 tbsp Sesame oil and 1 tsp Sugar (to balance the savory notes)


👩🍳 Step-by-Step Instructions
- Prepare the Acorn Jelly (Mook):
- If your mook is fresh and bouncy, simply slice it into bite-sized rectangles (about $\frac{1}{2}$-inch thick).
- Pro Tip: If the jelly has been refrigerated and feels stiff or cracks easily, blanch it in boiling water for 1–2 minutes until it becomes translucent and jiggly again. Plunge it into cold water, drain thoroughly, and then slice.
- Prep the Veggies:
- Wash and thoroughly dry the lettuce. Tear it into bite-sized pieces and set aside.
- Mix the Dressing:
- In a large mixing bowl, combine the tuna sauce, gochugaru, minced garlic, MSG, toasted sesame seeds, and sesame oil/sugar (if using). Stir well to create a paste-like dressing.
- Toss and Assemble:
- Add the torn lettuce to the bowl with the dressing and toss gently to coat.
- Add the sliced mook last. Handle with care! Acorn jelly is delicate and breaks easily. Gently fold the jelly into the seasoned lettuce using your hands or a rubber spatula until everything is beautifully coated.
- Garnish and Serve:
- Transfer to a serving plate, sprinkle with a few more sesame seeds on top, and serve immediately.
💡 Recipe Notes & Variations
Eat it fresh: This dish is best enjoyed the day it is made, as the lettuce will wilt and the jelly will release water if left in the fridge overnight.
Texture matters: Using a wavy crinkle-cutter knife to slice the mook not only looks beautiful but also helps the dressing cling to the jelly better.
Make it a meal: You can stretch this banchan into a larger salad by adding sliced cucumbers, shredded carrots, or toasted nori (seaweed) strips.
