Fusion · Easy · Serves 2

Doenjang butter pasta is the #109's Korean sibling: the same compound-butter logic, with doenjang — Korea's fermented soybean paste, miso's deeper, earthier cousin — melting into butter and pasta water over spaghetti. Five ingredients, twelve minutes, and the same lesson: a fermented paste is a fat format's best friend.

Quantities live in the recipe card.

Ingredients

- **Whisk the doenjang into the butter off the heat.** Doenjang is chunkier and saltier than miso — mash it through a fine sieve into the soft butter, or whisk hard, so the sauce is smooth. A paste lump in the final sauce is the one failure. - **The bridge:** doenjang is in the Korean aisle of any Asian grocery (the plastic tubs); miso bridges at a gentler depth — increase to 2 tbsp and add a drop of soy.

Step 1. **Boil the pasta shy of al dente**, reserving a mug of the starchy water. Checkpoint — the water runs cloudy — the starch cloud is the sauce's emulsifier, as at the #109.

Step 2. **Melt, mash, emulsify.** In a wide pan over the lowest heat, melt the butter with the garlic and gochugaru for 1 minute (the chili blooms in the fat); off the flame, mash in the doenjang until smooth, then add the drained pasta and pasta water by splashes, tossing vigorously 60–90 seconds to a glossy sauce that coats each strand. Checkpoint — the sauce should be a pale gold-amber silk, faintly flecked with chili — never broken or greasy (low heat, pasta water, vigor — the #109's law holds). Taste: savory-salty with a fermented depth and a slow warmth.

Step 3. **Crown and serve immediately.** Scallions, sesame seeds, and the optional parmesan (the both-cuisines move, and it works — doenjang and parmesan are both aged protein). Checkpoint — eating test: butter-silk noodles with the doenjang's deep, earthy funk riding under — rounder and more brooding than the #109's nori version — the chili's warmth arriving late, the sesame and scallion fresh over. It should taste like a pasta that spent a year in a Korean grandmother's kitchen, which is the entire fusion. Chef’s Note — the #109 and #132 pair is the block's compound-butter diptych: one paste per cuisine, one chassis. The general law (a fermented or roasted paste + butter + pasta water = a sauce) covers miso, doenjang, the #86's jaew bong, even the #99's balachaung — and the block's remaining pastas (#135, #149) are the law's further proof. Make one butter; keep the jar.

200 g spaghetti
50 g butter; 1½ tbsp doenjang (about 25 g)
1 tsp gochugaru (about 3 g) or a pinch of chili flakes
2 cloves garlic (about 8 g), grated; 1 scallion, sliced, plus more for the crown
A splash of pasta water; toasted sesame seeds; a spoon of parmesan, optional (the both-worlds move)

Troubleshooting

Symptom	Cause	Fix
Sauce grainy with paste	Doenjang lumped	Sieve it into the butter; mash smooth
Tastes flat, one-note	Under-salted or pasta-water-shy	Doenjang salts; adjust with the pasta water's starch
Greasy, broken	Butter overheated	The lowest heat; the emulsion is gentle

Storage, Make-Ahead & Variations

- Made and eaten in the moment; the doenjang-butter (sieving doubled) keeps 2 weeks as a log — the standing weeknight upgrade, the #109's note carries. - Variations: with mushrooms folded through (doenjang's best friend), the #59's bulgogi on top. The block's #109 is this recipe's Japanese mirror.
