Iโve always had a soft spot for two things in life: mayonnaise and prawns. So when a dish brings both of them together into a creamy, crispy, savory experience like udang mayonnaise, also known as ebi mayo, you can bet Iโm clearing a spot at the table.
My first memory of udang mayonaise was at a Chinese restaurant in Indonesia. We were celebrating something, maybe a birthday or one of those big family gatherings that automatically meant a round table full of food. Among all the dishes that arrived in synchronized chaos: hotplate tofu, stir-fried greens, fried chicken with salted egg yolk, there came a modest plate of golden-battered prawns, glistening in a pale, glossy mayonnaise sauce.

I loved it. Absolutely loved it. But the portion? So small. And in a typical family meal where we had to share everything, it felt like the plate disappeared within seconds. If I wanted more, I had to summon all my courage to ask my parents to order another round. But of course, there were other dishes we hadnโt even touched yet, and parents being parents, they said, โNext time.โ
Well, now Iโm an adult. And that โnext timeโ is every time I want it. I can make udang mayonaise at home, as much as I want. Okay, in moderation. But still, thereโs something deeply satisfying about recreating a childhood favorite and finally being in charge of the portion size.

The Story Behind Ebi-Mayo: Japanese-Chinese Fusion at Its Best
If youโve had ebi mayo in Japan, you might be surprised to know that this creamy prawn dish has strong ties to Chinese cuisine. The name ebi means shrimp in Japanese, and mayo… well, we all know what that is. Ebi mayo is a staple in many Japanese-Chinese restaurants, often served in izakayas (Japanese pubs) or on casual dinner menus.
Interestingly, ebi mayo was popularized in Japan by Iron Chef Chen Kenichi, whose cooking leaned heavily toward Sichuan-style Chinese food. He is credited for introducing and adapting several Chinese dishes for Japanese palates, and ebi mayo is said to be one of his signature creations. That explains the blend: the Chinese-style battered prawns coated in a Japanese-favorite ingredient: mayo.
So whether you call it udang mayonaise or ebi mayo, itโs really a celebration of cultural fusion. A dish that traveled across borders, evolved in interpretation, and still managed to retain its soul.
The Mayonnaise That Makes It Magic

Letโs be honest: not all mayonnaise is created equal. For udang mayonaise, I always reach for Kewpie. This Japanese mayo has a cult following for a reason. Itโs creamier, tangier, and just a bit sweeter than your average Western mayo. Made with egg yolks instead of whole eggs, and seasoned with a hint of rice vinegar or apple cider vinegar, Kewpie mayo has that umami punch that brings the sauce to life.
You could use regular mayonnaise in a pinch, but it wonโt be the same. The flavor profile would fall a little flat, and the sauce might feel too heavy. Kewpie keeps it light, velvety, and balanced, a perfect contrast to the crunchy fried prawns. If youโve never tried Kewpie before, trust me on this. Once you go Kewpie, itโs hard to go back.
How It Tastes: Crispy, Creamy, Slightly Sweet, and Completely Addictive
If you’ve never tried udang mayonaise before, let me try to put its magic into words. Imagine biting into a juicy shrimp wrapped in a light, crispy crust. Then comes the sauce: rich, velvety, and just the right balance of sweet, tangy, and savory. It coats your tongue with a gentle creaminess, followed by the warmth of umami and a hint of acid that cuts through the richness.
This isnโt your typical mayonnaise. The sauce in ebi mayo is often a blend of Kewpie mayo, condensed milk, lemon juice, and sometimes chili sauce. Itโs complex, multi-dimensional, and addictive in a subtle, comforting way. The sweetness never overwhelms, and the tanginess keeps you coming back for just one more bite.

The shrimp stay juicy on the inside while the outside remains crunchy, even under a layer of sauce. And that contrast: crisp shell, tender meat, creamy dressing is what makes udang mayonaise such a textural and flavor triumph. Itโs the kind of dish that disappears fast, whether served as an appetizer or as part of a larger meal.
Ingredients for Udang Mayonaise (Ebi Mayo)
Here are the ingredients youโll need to make crispy, creamy udang mayonaise or ebi mayo at home. I’ve included a few helpful notes and substitutions so you can adjust to your taste or what you have on hand.

For the Prawn Batter
- Fresh tiger prawn, peeled and butterflied. Tiger prawns are meaty and juicy, ideal for deep frying. You can also use vannamei or whiteleg prawns if tiger prawns arenโt available.
- Egg white helps the coating stick better and creates a light crisp crust when fried.
- Corn starch is used in both the marinade and outer coating for that extra crunch. Potato starch is a great alternative for a fluffier texture.
- Baking soda helps tenderize the prawns slightly and contributes to a crispier finish. You can skip this if you prefer a more natural bite.
- Salt enhances the base flavor of the prawn before it gets coated in sauce.
- Garlic powder adds a subtle savory note to the marinade.

For the Coating
- More corn starch for dredging. This is what gives the fried prawns their crispy outer layer. You can use potato starch or a combination of flour and cornstarch, though pure cornstarch gives the best result.

For the Mayonnaise Sauce
- Mayonnaise is the star of the sauce. Kewpie mayo is highly recommended for its rich, umami-packed flavor. If unavailable, choose a full-fat mayo with a creamy texture.
- Condensed milk adds sweetness and a creamy depth to the sauce. You can substitute with honey and a splash of cream if you prefer it less sweet.
- Honey balances the tang and makes the sauce more rounded. Maple syrup can be used as a backup.
- Lime juice adds brightness and cuts through the richness. Lemon juice works as a substitute.
- A pinch of salt enhances all the flavors in the sauce, so donโt skip it even if the mayo is already seasoned.
These ingredients come together to create the perfect balance of crunchy, creamy, sweet, and tangy in every bite of your homemade udang mayonaise.
How to Butterfly the Prawns for Udang Mayonaise
To get that plump, evenly cooked texture and help the sauce cling better, it’s best to butterfly the prawns before cooking. This simple step not only makes them cook faster but also gives them that restaurant-style look.


Hereโs how to do it:
- Peel and devein the prawns, leaving the tails on if you prefer a more elegant presentation.
- Place each prawn belly-side down on a cutting board.
- Using a sharp knife, make a cut along the back of the prawn, starting from the head end down to the tail.
- Cut deeply enough to expose the white inner flesh, but not all the way through. You want to stop just before splitting the prawn into two separate halves.
- Gently press the prawn open like a book. It should now lay flatter and look slightly curled, ready for battering and frying.
This butterflying technique helps the prawn cook more evenly, gives a crunchier surface area, and makes it easier to absorb that rich, creamy ebi mayo sauce in every bite.
Playing Around: Variations You Can Try
The beauty of udang mayonaise lies in its flexibility. Once youโve mastered the basics, you can tweak it to suit your taste or dietary preferences. Here are a few ideas:
- Spicy Ebi Mayo: Add a dab of Sriracha, gochujang, or wasabi to the sauce to give it a spicy edge.
- No-Fry Version: Air-fry the prawns or lightly pan-fry them with a cornstarch coating if you want something a bit lighter.
- Tamarind Mayo: For a Southeast Asian twist, try adding a splash of tamarind paste to the sauce.
- Tropical Touch: Serve the prawns on a bed of shredded lettuce with some mango or pineapple salsa for a fresh, summery version.
- Vegan Version: Use vegan prawns (yes, they exist!) and swap the mayo with a plant-based alternative. Youโll be surprised how close it gets to the original.
Thereโs no wrong way to enjoy udang mayonaise, really. As long as thereโs that signature creamy-mayo-coated crunch, youโre on the right track.

What to Watch Out For: Tips and Tricks
Even though udang mayonaise is a relatively simple dish, there are a few key things to pay attention to if you want restaurant-quality results at home:
- Balance the Sauce: Taste the sauce before adding it to the shrimp. Everyoneโs sweet-salty preference is different, so feel free to adjust the ratio of mayo, condensed milk, lemon juice, or chili sauce to suit your palate.
- Use Fresh Prawns: Donโt skimp on the main ingredient. Fresh or high-quality frozen prawns make a big difference in taste and texture. Peel and devein them properly to avoid any bitterness.
- Dry Before Frying: Make sure the prawns are as dry as possible before coating them in batter. Any moisture will cause the oil to splatter and ruin the crust.
- Fry in Batches: Donโt overcrowd the pan. Frying too many prawns at once lowers the oil temperature and leads to soggy shrimp.
- Control the Heat: The oil should be around 170โ180ยฐC (340โ360ยฐF). Too hot, and the batter burns before the shrimp is cooked. Too cold, and it becomes greasy.
- Serve Immediately: This is not a dish that sits well. Udang mayonaise is best enjoyed hot, fresh out of the fryer, with the sauce tossed in right before serving.
Nutritional Value of Udang Mayonaise (Ebi Mayo)
While udang mayonaise is a delicious treat, itโs good to be mindful of its nutritional content, especially if you’re watching your intake of fats or calories.
On average, a single serving (about 4โ5 medium prawns with sauce) contains:
- Calories: ~300โ400 kcal
- Protein: ~18โ22g
- Fat: ~25โ30g (mostly from mayo and frying oil)
- Carbohydrates: ~10โ15g (from cornstarch or flour coating and mayo sweeteners)
- Sodium: ~400โ600mg depending on sauce ingredients
If youโd like to lighten it up, consider using an air fryer, reducing the mayo, or adding more greens like shredded cabbage or lettuce to make it a fuller meal with added fiber.
