Gochujang Mayo (Korean Spicy Mayonnaise Sauce)

Buy classic gochujang paste in the small red square tub — this is the authentic Korean product, fermented from rice, soybeans, chili, and barley malt. Sunchang (선창) is the gold standard in Korea and stocked in most Asian groceries; CJ Haechandle is the mass-market option, widely available in chain supermarkets internationally. The thinner 'gochujang sauce' in squeeze bottles is diluted paste with sugar and stabilizers added — it is a marketing product for Western markets, the flavour is flat and the fermented depth is mostly gone. Check the heat number on the tub: 1 to 3 is mild, 4 to 5 is medium (the default for sauces and dips), higher than 5 is too hot for mayo.

There is no perfect substitute: the fermented sweet-spicy umami is unique to gochujang. Sriracha gives heat and acidity but no fermented depth; use 1.5 tablespoons of sriracha plus ½ teaspoon of soy sauce for umami and a pinch of brown sugar to bridge the gap. Sambal oelek is further from the original — too chili-forward and not sweet enough. A homemade alternative: 1 tbsp tomato paste plus ½ tbsp miso paste plus 1 tsp sriracha plus ½ tsp sugar gives a similar fermented, sweet-spicy profile. For authenticity, just buy gochujang — a tub costs about 4 dollars and keeps in the fridge for 6 months or more, easily worth it within a week of cooking.

In a sealed glass jar in the fridge, gochujang mayo keeps for 7 to 10 days — gochujang and the acidic mayo base work as natural preservatives. The flavour actually deepens by day 2 or 3 as the garlic integrates, the gochujang's edge mellows, and the vinegar settles. Signs of spoilage: oil separating more than 2 mm on the surface, or sour smell outside the gochujang notes. Freezing is a hard no — mayo separates into water and oil on thawing, and the emulsion does not come back even with whisking. Make small batches of 100 to 150 g for 3 to 4 days of use.

Best matches are foods where fat and starch need a hot-acidic counterpoint: french fries (sweet potato especially — the sweetness echoes the gochujang's), mini corn dogs, tempura shrimp, poke bowls, Korean fried chicken, burgers. On sandwiches it replaces regular mayo, especially with grilled chicken or pulled pork. As a salad dressing, thin it 1:1 with rice vinegar and olive oil for a neutral 'Asian' dressing for greens or coleslaw. On rice bowls or in kimbap as a spread instead of soy sauce. Does not pair with dairy products (cheese, sour cream) — they compete for the milky-fat lane.

Two versions work. Vegan: use aquafaba or soy-based mayo (Hellmann's Vegan, Just Mayo, or similar) at the same ratio — the texture is nearly identical, the flavour slightly more neutral; check the gochujang label for fish extract, which some Korean brands include. Low-calorie: replace 120 g of mayo with 60 g of 5 percent Greek yogurt plus 60 g of regular mayo — calories drop from 110 to about 70 per serving, but the sauce becomes more acidic, so add an extra ½ teaspoon of honey to balance. A pure yogurt version with no mayo at all separates within an hour — the emulsion is unstable without oil, do not bother.
