I started Ahnest Kitchen in 2018 during my “quarter-life crisis.” I was very unhappy and unfulfilled in my first full-time job, and I hoped this wasn’t something that I just needed to get used to and accept as an adult. During those years one thing made me feel fulfilled: Umma’s food. It wasn’t just the taste and flavor that comforted me; the process of making these dishes also fascinated me. Learning and replicating the recipes felt like therapy, and sharing and cooking these recipes for others brought me joy, just as it does for Umma. This newfound practice was exactly what I needed during this phase of my life, and it eventually motivated me to collect all of Umma’s recipes to keep forever. Initially, I documented them in my notebook until I decided to upload them online to share with enthusiastic cooks around the world. Soon enough, people took notice of our work, and traction followed. We eventually received our first opportunity to collaborate with a Korean food brand we both grew up with. Umma and I felt beyond excited and determined to develop a unique recipe that would not disappoint. When we took our first bites of the final dish—after multiple rounds of testing and critiques—we both nodded in agreement and said, “This is it!” That very dish was this unique noodle masterpiece, which relies on gochujang to create a sauce that delivers the perfect balance of spice, tang, and sweetness. Here we opt for angel hair pasta instead of somyeon (thin wheat noodles) for a different flavor and texture, as well as added convenience.

Umma’s Kitchen Wisdom
I use a mandoline to slice the cabbage about ⅛-inch thick. You can substitute fish sauce for the tuna extract sauce: Use 2 Tbsp. fish sauce and reduce the sugar to 2 Tbsp.

Recipe information

  • Total Time

    50 minutes

  • Yield

    4–6 servings

Ingredients

½ cup (176 grams) gochujang
½ cup maesil cheong (plum extract syrup)
¼ cup tuna extract sauce
¼ cup distilled white vinegar
¼ cup toasted sesame oil
3 Tbsp. minced garlic
3 Tbsp. sugar
2 Tbsp. gochugaru
12 oz. (340 grams) angel hair pasta
3 Persian cucumbers (240 grams), cut into 3‑inch matchsticks, divided
4 cups (226 grams) very thinly sliced green cabbage, divided
4 tsp. sesame seeds, toasted
2 or 3 hard-boiled large eggs, halved
Lemon wedges, for serving

Preparation

  1. Step 1

    Whisk ½ cup (176 grams) gochujang, ½ cup maesil cheong (plum extract syrup), ¼ cup tuna extract sauce, ¼ cup distilled white vinegar, ¼ cup toasted sesame oil, 3 Tbsp. minced garlic, 3 Tbsp. sugar, and 2 Tbsp. gochugaru together in a large bowl; set aside.

    Step 2

    Bring 2½ quarts water to a boil in a large, wide pot. Add 12 oz. (340 grams) angel hair pasta and cook, stirring occasionally, until softened, about 4 minutes. Drain the noodles and rinse under cold running water until chilled. Drain and gently squeeze the noodles to remove excess liquid.

    Step 3

    Add the pasta, 2 Persian cucumbers (160 grams), cut into 3" matchsticks, and two-thirds of 4 cups (226 grams) very thinly sliced green cabbage, to the bowl with the sauce. Using your gloved hands, gently toss the mixture until the noodles and vegetables are evenly coated with the sauce. Divide the pasta among individual serving bowls. Spoon any sauce left in the mixing bowl around the pasta, then sprinkle with 4 tsp. sesame seeds, toasted. Top with the remaining 1 Persian cucumber (80 grams), cut into 3‑inch matchsticks, remaining one-third of 4 cups (226 grams) very thinly sliced green cabbage, and 2 or 3 hard-boiled large eggs, halved. Serve with lemon wedges.
