Mamón Chino Ceviche: Costa Rica’s Bright, Zesty Vegan “Ceviche” You’ll Crave Again

Ceviche usually brings seafood to mind, but Costa Rica has a cheeky, tropical workaround that feels just as fresh and far more surprising. Mamón chino ceviche takes the juicy flesh of rambutan (that spiky red fruit you’ll spot piled high at roadside stands and farmers’ markets) and turns it into a citrusy, crunchy, herb-packed bowl of pura vida refreshment. It’s sweet, tangy, sharp, and cooling—exactly what you want when the day is warm, your schedule is busy, and your taste buds want something that snaps.

What is mamón chino (rambutan) in Costa Rica?

Mamón chino is rambutan: a bright red, soft-spiked fruit with translucent, grape-like flesh that tastes sweet with a lightly tart edge. It’s related to lychee and longan, and Costa Rica grows it happily in warm, humid zones. Costa Rica Découverte+1

Mamón chino is mainly a rainy-season fruit, with season starting around June/July and peaking around September and October. MytanFeet+2Pura Vida Moms+2

Why does mamón chino work so well in a vegan ceviche?

Mamón chino works because its texture is tender yet springy, and its sweet-tart flavour plays brilliantly with lime, onion, chilli, and coriander. When you chop it small and bathe it in citrus, it takes on that ceviche “zing” without needing fish at all—just bright acidity, crunch, and a little heat.

What does mamón chino ceviche taste like?

Mamón chino ceviche tastes like a tropical salsa with ceviche attitude—citrusy, lightly sweet, sharply fresh, and full of crunch. Think of it as the lovechild of a fruit salad and a classic tico ceviche, but with a cleaner, lighter finish.

What ingredients do you need for mamón chino ceviche?

You need a handful of fresh produce and strong citrus, and you can keep it simple or make it party-level fancy.

Core ingredients

• Mamón chino (rambutan), peeled and de-seeded

• Fresh lime juice (the main event)

• Red onion, finely diced

• Cucumber, diced

• Sweet pepper (red or yellow), diced

• Fresh coriander (cilantro), chopped

• Salt and black pepper

Optional upgrades (highly recommended)

• Orange juice (rounds out the lime bite with gentle sweetness)

• Jalapeño or chilli (for clean heat)

• Ripe avocado (for creamy contrast)

• A splash of coconut water (for a softer, beachier vibe)

• Finely chopped mango or pineapple (if you like it more fruit-forward)

How do you make mamón chino ceviche at home?

You make mamón chino ceviche by chopping rambutan and vegetables, then marinating everything in fresh citrus until the flavours meld.

Here’s a reliable, market-to-table method (serves 2–4 as a starter):

Ingredients

• 10 mamón chino fruits, peeled, seed removed, chopped

• 1 red bell pepper, finely diced

• 1 cucumber, peeled and diced

• ½–1 red onion, finely diced (to taste)

• 1 jalapeño, finely chopped (optional)

• ¼ cup fresh coriander, chopped

• Juice of 4 limes

• Juice of 1 orange (optional, but lovely)

• 1 tsp salt, then adjust

• ½ tsp black pepper

• Avocado slices, to serve (optional)

Steps

1. Prep the mamón chino. Peel, remove the seed, and chop the flesh into bite-sized pieces (small cubes are best for ceviche-style eating).

2. Build the crunch. Add pepper, cucumber, onion, chilli (if using), and coriander to a bowl with the chopped fruit.

3. Add the citrus. Pour in lime juice (and orange juice if using), then toss thoroughly so everything is coated.

4. Season. Add salt and pepper, then taste and tweak—more lime for sharper, more salt for punchier, more coriander for greener.

5. Chill. Refrigerate for 30 minutes so the flavours settle into each other.

6. Serve. Spoon into small bowls or lettuce cups, top with avocado, and bring something crunchy to the table.

How long should you marinate mamón chino ceviche?

You should marinate it for about 20–40 minutes for the best balance of bright flavour and crisp texture. Longer is fine if it’s chilled, but after a few hours the cucumber and onion start to soften, and the whole bowl turns from “snap” to “slouch.”

What should you serve with mamón chino ceviche?

You should serve it with something crisp and salty so the citrus and fruit pop even harder.

Best pairings

• Tortilla chips (classic and easy)

• Tostadas or plantain chips (extra crunch)

• Lettuce cups (light, tidy, picnic-friendly)

• Rice and beans on the side (if you want it more filling)

• A simple green salad with a lime vinaigrette

What are the best tips for peeling mamón chino without making a mess?

You can peel mamón chino neatly by scoring the skin around the middle and twisting it open like a tiny, spiky planet.

Try this

• Use a small knife to make a shallow cut around the “equator.”

• Twist both halves in opposite directions

• Pop out the flesh, then remove the seed

• If the flesh clings tightly to the seed, slice along one side and lift it away (less tugging, more dignity)

How can you customise mamón chino ceviche to match your taste?

You can customise it by adjusting heat, sweetness, crunch, and “body” depending on what you want the bowl to do.

Easy flavour tweaks

• More classic ceviche bite: extra lime + extra onion + a pinch more salt

• More tropical and mellow: add orange juice or a splash of coconut water

• More heat: jalapeño, chilli flakes, or a tiny spoon of hot sauce

• More filling: add black beans, hearts of palm, or diced cooked sweet potato

• More crunch: diced jícama, radish, or toasted pepitas

Can you make mamón chino ceviche ahead of time?

Yes, but it’s best made the same day for peak crunch and brightness. Store it covered in the fridge and aim to serve within 24 hours; if it sits longer, the vegetables soften and the citrus flavor can become a bit flat.
