If you read our post on what a caldosa actually is, you already know the basics: fresh ceviche poured into a bag of Picaritas chips, eaten with a spoon right on the beach. But what goes on top? What are the condiments? And what does the finished product actually look like when you're holding it? We captured the whole thing on video at a real beach vendor in Jacó — the setup, the build, and the final result. Here's exactly what goes inside a caldosa, step by step. At www.jacobeachchef.com we live and breathe Jacó beach food culture, and a caldosa is one of the most authentic things you can eat here.
The condiment station
Every caldosa vendor in Costa Rica runs a tight little setup — usually a cooler or a folding table right on the sand. What's on that cooler tells you everything about how seriously they take their craft. Watch this vendor show you exactly what he's working with:
What you're seeing on that cooler lid is a very specific lineup of Costa Rican condiments. It's not random — this is the traditional caldosa build, and a good vendor has every component dialed in. Let's break it down.
The Picaritas bag
The chip bag is the bowl. Vendors use Picaritas — Costa Rica's iconic yellow-bag corn chip, lightly salted and sturdy enough to hold up when the ceviche goes in without turning instantly to mush. You'll spot the bag sitting in a small green cup holder on the cooler — it keeps the bag upright while the vendor loads it up. Picaritas is a distinctly Costa Rican brand, and if you've been reaching for a Doritos comparison, this is not that. They're lighter, a little salty, and they absorb the ceviche liquid just enough to get soft and flavorful without completely dissolving. That contrast — crispy chips at the edges, wet chips at the center — is a big part of why a caldosa works.
Banquete Mayonesa
The green pouch on the cooler is Banquete Mayonesa — a Costa Rican mayo squeeze pouch that's a staple in street food across the country. It's richer and slightly tangier than American mayo, and it gets drizzled across the top of the ceviche once it's in the bag. It sounds unconventional if you've never had one, but it works — it adds creaminess and rounds out the acidity of the lime in the ceviche. Every serious caldosa vendor in Jacó has it on the cooler.
Lime juice and ketchup
The plastic bottle with yellow-green liquid is fresh squeezed lime juice — the vendor uses it both in the ceviche mix itself and as a finishing drizzle over the top. Some vendors also add a shot of ketchup (Roma is the most common brand in Costa Rica) as a sweet-tangy counterpoint to the lime and mayo. It sounds like an unusual combination until you actually eat one, and then it makes complete sense. The lime cuts through the mayo, the ketchup adds a hint of sweetness, and together they tie everything into a sauce that soaks into the chips from the bottom up.
The ceviche — the star of the show
Everything else on the cooler is support. The ceviche is the main event. Costa Rican ceviche is typically made with fresh white fish (often tilapia, corvina, or sea bass), cured in lime juice with red onion, cilantro, and peppers. Beach vendors who do it right have a whole cooler full of the fresh-mixed batch. The ceviche goes in as the main body of the caldosa — a generous ladleful right into the open chip bag, filling it from the bottom up so the chips at the base start softening immediately while the ones on top stay crispier.
The finished result
Once the ceviche is in and the condiments are drizzled over the top, you're holding something that looks like this:
That's the real thing. White fish chunks, red onion, fresh cilantro, colorful peppers, all swimming in a reddish ceviche liquid enriched with lime and mayo, a spoon sticking up out of the bag, the Pacific just a few steps away. This is exactly what you'll get from a beach vendor in Jacó for a few hundred colones — maybe $1.50 to $3 USD depending on the vendor and size. It's one of the best food values you'll find anywhere in Costa Rica, and eating one while sitting on the beach with the waves coming in is a quintessential Jacó experience.
Where to find a caldosa in Jacó
Caldosa vendors in Jacó set up wherever the beach crowd gathers — near the main surf break, along the beach path between the hotels, and around the public beach access points especially on weekends and holidays. They're easy to spot: a cooler, a folding setup, usually under a palm tree or a small beach umbrella. There's no permanent storefront — they come to the beach, and you find them by walking the sand. If you're at a villa or condo a little further from the main beach, ask your host or the local staff — they'll know exactly who the best vendor is and roughly when they'll be out. And if you want to taste authentic Jacó street food on your trip, a caldosa should be high on your list.
