Callo de Hacha: What It Is, Types & How to Cook It | Friizco
Compartir
If you have ever visited a seafood restaurant in Mexico, you may have seen callo de hacha on the menu.
It is prized for its tender texture, delicate ocean flavor and versatility in dishes ranging from ceviche and aguachile to grilled preparations.
But what exactly is callo de hacha? Is it the same as a scallop? And what is the best way to cook it?
In this guide, we explain what callo de hacha is, the main types found in Mexico, how to prepare it and what to look for when buying it.
What Is Callo de Hacha?
Callo de hacha is the edible muscle of several large marine bivalves commonly known in Mexico as hachas or pen shells.
The commercial portion is primarily the large adductor muscle that the shellfish uses to open and close its shell.
Because only the firm muscle is usually sold, the final product resembles a large scallop.

Is Callo de Hacha the Same as a Scallop?
Not exactly.
Both are bivalve mollusks and the part commonly eaten is the adductor muscle, which explains their similar appearance.
Traditional callo de hacha from Mexico may come from pen-shell species belonging to genera such as Atrina and Pinna.
Regular sea scallops belong to different biological groups.
For shoppers, however, both can provide a similar culinary experience: a tender but firm bite and a naturally delicate seafood flavor.
Main Types of Callo de Hacha in Mexico
Mexico has several species and commercial presentations that may be sold as callo de hacha.
Among the most common names you may encounter are:
Hacha China or Media Luna
This type is commonly associated with Atrina maura and is often recognized for its rounded or half-moon appearance.
Friizco will soon add a Callo de Hacha Media Luna presentation to the catalog, which will make it easier to compare different types and sizes directly.
Hacha Larga
This name is often associated with Pinna rugosa, another species harvested commercially in Mexican waters.
Hacha Botijona
This commercial name is associated with Atrina tuberculosa.
Hacha Lisa
Another recognized commercial type is Atrina oldroydii, commonly referred to as hacha lisa.
For most customers, however, the exact species is not always the most important factor.
Size, presentation, texture, freezing method and intended use are usually more relevant when choosing which product to buy.
What Does Callo de Hacha Taste Like?
Callo de hacha has a mild, clean seafood flavor.
Its texture is one of its most distinctive characteristics.
When prepared correctly, it should be:
- tender
- slightly firm
- juicy
- delicate rather than rubbery
Because the flavor is subtle, it works especially well with simple ingredients such as lime, garlic, butter, olive oil and chile.
Fresh vs Frozen Callo de Hacha
Both fresh and frozen callo de hacha can work well.
Frozen presentations are especially practical because they can be stored longer and portioned according to your needs.
You can currently find Frozen Callo de Hacha at Friizco for delivery in Playa del Carmen.
The key is proper thawing.
Whenever possible, thaw it slowly in the refrigerator instead of leaving it at room temperature.
Once thawed, remove excess moisture before cooking.
This step is especially important if you plan to sear it, because excess water can prevent browning.
How to Cook Callo de Hacha
Callo de hacha benefits from short cooking times.
Like scallops, it can become chewy if it is cooked for too long.
Pan-Seared Callo de Hacha
Pan-searing is one of the easiest and most popular methods.
Start by drying the surface with paper towel.
Season lightly with salt and pepper.
Heat a skillet until hot, add a small amount of cooking oil and place the pieces in the pan without overcrowding.
Cook briefly on each side until the exterior develops a golden surface while the center remains tender.
For larger pieces, cooking time may be slightly longer.
Grilled Callo de Hacha
Callo de hacha also works well on the grill.
Lightly coat the surface with oil and season with salt and pepper.
Because the pieces cook quickly, avoid leaving them over high heat for too long.
Finish with lime, lemon or a little garlic butter.
Callo de Hacha for Ceviche or Aguachile
Callo de hacha is commonly used in cold seafood preparations because its texture works well when sliced thinly.
Popular ingredients include:
- lime
- cucumber
- red onion
- cilantro
- chile
- avocado
For raw or lightly cured preparations, use seafood suitable for that intended use and maintain proper refrigeration and food-handling practices.
Citrus juice changes the texture and appearance of seafood, but it should not be considered a substitute for proper handling and refrigeration.
Callo de Hacha with Garlic Butter
Another simple preparation is garlic butter.
After searing the callo, reduce the heat and add a small amount of butter and chopped garlic.
Baste briefly and finish with lemon or lime.
The key is to avoid continuing to cook the seafood for too long after adding the butter.
How Much Callo de Hacha Should You Buy?
The amount depends on whether it is being served as an appetizer or a main course.
For appetizers, smaller portions may be enough because callo de hacha is often served alongside other seafood.
For a main course, you can increase the portion depending on the size of the pieces and the side dishes.
Some products may also use size classifications such as 10–20, which help indicate the approximate size or count used by the supplier.
Always check the specific product presentation before ordering.
How to Avoid Overcooking Callo de Hacha
The most common mistake is leaving it in the pan too long.
For better results:
- dry the surface before cooking
- use a hot pan
- avoid overcrowding
- cook in small batches
- use simple seasoning
- remove from heat as soon as the texture is firm but tender
The goal is to preserve moisture and tenderness.
What Goes Well with Callo de Hacha?
Because its flavor is delicate, simple accompaniments work very well.
Good options include:
- lime or lemon
- garlic
- butter
- olive oil
- chile
- cilantro
- avocado
- cucumber
- grilled vegetables
- rice
- fresh salads
