Spicy Mayo
with Egg Yolks, Rice Vinegar, MSG & Sriracha
Kewpie logic from scratch: yolks whisked rich, seasoned with rice vinegar and a defended pinch of MSG, then spiked salmon-pink.

This jar was promoted out of the chicken karaage page, where it started as the dip whisked together while the oil heated and ended as the reason the platter emptied before anyone sat down. Then it started showing up uninvited: on shrimp, inside sandwiches, over roasted broccoli eaten standing at the counter. A sauce that keeps leaving its own recipe gets a cellar page. The build is kewpie logic rather than a kewpie clone: yolks only, rice vinegar, sugar, and MSG, the Japanese jar's whole argument, made fresh and then spiked to salmon-pink.

The Tools
- Medium bowl (the emulsion) · Set it on a damp towel so it holds still; whisking a mayonnaise is a two-handed job done with one.
- Whisk
- Liquid measuring cup with a spout (the oil) · The thin, controlled pour is the technique; a spout is cheap insurance.
- Flexible spatula
- Glass jar with a tight lid (storage)
- Measuring spoons (optional)

The Spicy Mayo
Why this works Kewpie mayo is yolks only, rice vinegar, and MSG, which is why it eats richer and rounder than the American jar, and those three decisions are the whole recipe. Yolks only, because the white is water and albumin that dilutes without contributing; the yolk carries the lecithin, and lecithin is the machine. Each phospholipid molecule has a fat-loving tail and a water-loving head, so as the whisk shears the incoming oil into droplets, lecithin coats each one and holds it apart from its neighbors. A cup of oil becomes millions of suspended beads, and millions of beads packed tight is why a liquid fat turns into something that holds its shape on a spoon. The one rule is rate: the thread of oil can never outrun the whisk, especially in the first minute before the emulsion has body enough to grab. Rice vinegar over distilled because its acidity is softer and faintly sweet, which lets the seasoning sit forward without turning the sauce sharp. The sugar is half a teaspoon of balance, not sweetness. And the MSG is load-bearing and defended without apology: it is pure glutamate, the same molecule that makes tomatoes, parmesan, and soy sauce taste like more, and a pinch of it here is the difference between mayo and THE mayo. Sriracha finishes the job with three things in one squeeze: chile heat, fermented garlic tang, and a little more sugar and salt. Huy Fong is the famous rooster, but the spec matters more than the label: a fermented red jalapeno sauce with garlic, thick enough to hold a line on a plate. If you keep a bottle you love, it is correct. The Duke's shortcut is a real fork, not a failure: American mayo plus an extra raw yolk, the vinegar, sugar, and MSG whisked in takes you most of the way to kewpie in two minutes, and the page carries it honestly. From scratch is rounder; the fork is faster; both are this sauce.
- 2 large, cold Egg yolks · Yolks only; the whites go to the freezer for a future meringue. The Duke's fork: skip the yolks and oil, start from 1 cup Duke's plus one extra raw yolk, and pick up at the seasoning. Two minutes, most of the way there.
- 1 tbsp (15ml), plus more to taste Rice vinegar · Unseasoned. The softer, faintly sweet acid is half of what makes this read Japanese instead of deli.
- 1/2 tsp Sugar
- 1/4 tsp MSG · Ajinomoto from the Asian grocery, sold as umami seasoning. Load-bearing and unapologetic: pure glutamate, the same molecule that makes tomatoes and parmesan taste like more.
- 1/2 tsp Fine salt
- 1 cup (220ml) canola, sunflower, or rice bran Neutral oil · Neutral is the spec; olive oil turns bitter under a whisk and picks a fight with the chile.
- 2 tbsp, plus more to taste Sriracha · The spec over the label: a fermented red jalapeno sauce with garlic, thick enough to hold a line on a plate. Huy Fong's rooster is the shelf standard; Underwood Ranches is the original farm's own bottle and a shade fresher.

Season the yolks 2 min hands-on
Whisk the yolks, rice vinegar, sugar, MSG, and salt in the bowl until the sugar dissolves and the mix pales slightly, about 30 seconds. Set the bowl on a damp towel so it stays put.
Look for Smooth, a shade paler than the yolks went in, no sugar grit against the whisk.
Take care -
Build the emulsion 8 min hands-on
Whisking constantly, pour the oil in the thinnest thread you can manage, a few drops at a time for the first minute, widening the stream only once the mixture visibly thickens and holds the whisk's tracks.
Look for The turn happens fast around the quarter-cup mark: it goes from loose and yellow to thick, pale, and glossy, and a ribbon off the whisk sits on the surface for a beat.
Take care Oil faster than the yolks can take it and the whole thing breaks to a greasy slick, almost always in the first minute. Rescue: fresh yolk in a clean bowl, then whisk the broken batch back in drop by drop; it comes back every time. -
Spike it 2 min hands-on
Whisk in the sriracha a tablespoon at a time, tasting between. The order on the tongue should be rich first, heat second, with the vinegar tang arriving underneath; stop while the mayo still tastes like mayo.
Look for A soft salmon-pink that holds its shape on a spoon. If it reads heat before it reads rich, you have gone past the food it is for.
Take care -
Jar and chill 1 min hands-on · 30 min wait
Scrape into the jar, lid it, and refrigerate at least 30 minutes before serving so the vinegar and glutamate settle into the fat. Stir once before it goes to the table.
Look for After the chill it tightens a shade and tastes like one sauce instead of mayo with hot sauce on top.
Take care
When it goes wrong
| Problem | Cause | Fix |
|---|---|---|
| Broke into a greasy slick | Oil poured faster than the yolks could emulsify it, almost always in the first minute | Fresh yolk in a clean bowl, whisk the broken batch back in drop by drop; it comes back every time |
| Tastes flat next to fried food | Missing the MSG or under-salted | The MSG pinch is load-bearing; add it, then salt to the edge of too much, because a cold dip next to hot food eats quieter than it tastes |
| Heat swamps everything | Heavy hand with the sriracha | Whisk in a spoonful of unspiked mayo if any was held back, or a teaspoon of oil and a pinch of sugar; next time spike a tablespoon at a time |
To the Table
Serve it cold in a shallow bowl, dusted with togarashi if sesame is welcome at the table.
The founding deployment is the chicken karaage (see chicken-karaage), whose page builds a sized-for-the-night batch of this same sauce inline when the cellar jar is empty. Lemon first, mayo second; the order matters.
It earns its keep everywhere crisp meets rich: crispy fried shrimp, a fried chicken sandwich in place of plain mayo, and swiped hot over roasted broccoli or charred carrots, where the heat wakes the sauce up.
The batch holds 4 days refrigerated under a tight lid; the raw yolks and the vinegar set the clock. Clean spoon every time.

Priced per 2-tablespoon serving, about 10 of them to a 1 1/4-cup batch, and the number is honest about what mayonnaise is: nearly a cup of oil holding hands with two yolks, so the fat line is the recipe. Pareve, gluten-free, dairy-free, and nut-free as written; the yolks are the only allergen aboard unless the togarashi dusting rides along with its sesame. FODMAP honesty: sriracha's fermented garlic is the load, and the plain-chile path below clears it without dimming the jar. The MSG pinch adds sodium in the same league as the salt and less than most people fear; glutamate is the point, not a problem. FOOD SAFETY: the yolks stay raw, so use fresh refrigerated eggs, or pasteurized ones if anyone at the table is pregnant, elderly, or immunocompromised.
Words We Used
- Kewpie
- The Japanese mayonnaise in the soft squeeze bottle: egg yolks only, rice vinegar, and MSG, richer and rounder than American mayo. This jar borrows its logic rather than cloning its label.
- Lecithin
- The emulsifier in egg yolk. Each molecule has a fat-loving tail and a water-loving head, so it coats sheared oil droplets and holds them suspended, which is how a cup of liquid oil becomes a sauce that stands on a spoon.
- MSG (monosodium glutamate)
- The sodium salt of glutamic acid, the amino acid behind umami. Chemically identical to the glutamate in tomatoes, parmesan, and soy sauce; a pinch seasons for savoriness the way salt seasons for salt.
- Sriracha
- A fermented red jalapeno-garlic hot sauce in the Thai style, made famous in America by Huy Fong's rooster bottle. Thick, tangy, garlicky, and medium-hot: the spec this sauce leans on.
