Caldo de Siete Mares + VIDEO

This is a sponsored post in partnership with Mazola® Corn Oil.

Caldo de Siete Mares (or Mexican Seven Seas Soup) is a dish that I learned back when I visited my grandfather.

We are from the State of Durango, a landlocked state, but he moved to Baja California late in life. Baja is surrounded by water, and their recipes are heavy on seafood. 

I visit his grave in Tijuana, B.C. on Dia de Muertos every year. It’s a time to remember his beautiful life and the gifts he gave us. 

He introduced me to many foods that are not common in our native Durango – Birria de Res, Camarones a la Diabla, and this incredibly tasty soup. 

Ingredients

Seven types of seafood are used to make this soup, hence the name.

You can mix and match whatever type of seafood you find at the store. Other seafood options – mussels, lobster, or baby scallops. 

Very Important: Use a thick, meaty fish like cod, monkfish, pollock, or halibut. 

To bring down the cost of the soup, use frozen seafood. OR, add more of the less expensive ingredients and only add a few of the more pricey ingredients. 

How to Make Homemade Shrimp Broth

• Remove the shells from the shrimp. 
• Place the shells in a stock pot. 

You can skip this step completely and use store bought seafood broth OR vegetable broth. 

Homemade seafood broth can also be made using fish, similar to the one made in Caldo de Pescado.

Pro Tip: 

Buy small shrimp. They will fit on a spoon better. 

• Add water, onion, garlic, bay leaf, salt and pepper. 
• Boil for 20 minutes. 
• Remove the shells, onion, bay leaf, and garlic.  

See the shrimp shells? They will turn pink. 

Save yourself some time and do this in advance. It freezes well for up to 4 months in a sealable plastic bag. 

The depth of flavor that this homemade shrimp broth gives the soup is incomparable.

How to Make Guajillo Sauce

• Remove the stems. 
• Cut lengthwise and remove the seeds. 
• Cover with water and bring to a boil. 

Once the water begins to boil. Turn the heat off and let the chiles sit in the hot water. 

Chiles take about 5-7 minutes to rehydrate in hot water. 

Similar to Caldo de Camaron, the guajillo sauce is NOT spicy and gives the soup another layer of flavor. 

Note: Other versions of this soup are made with chipotle peppers or just tomato sauce. 

• To a blender, add the rehydrated chiles, tomatoes, onion, garlic, salt, and water. 
• Blend until smooth. 

Guajillo Sauce is a traditional sauce made in lots of our authentic Mexican recipes. 

Save some from another dish, and skip this step. 

It freezes well for up to 4 months in a sealable plastic bag. 

How to Assemble The Soup

• Heat the Mazola® Corn Oil into a large stock pot. 
• Strain the guajillo sauce into the pot. 
• Discard any remaining bits of chile in the strainer. 
• Cook for 10 minutes, stirring occasionally. 

Mazola® Corn Oil is a hearty-healthy* cooking oil that has multiple purposes for you and your family – baking, grilling, even good as a marinade. 

When the sauce is cooked in the oil, it will become slightly thicker and richer. 

If you would like to add carrots or potatoes, add them here with sauce. 

• Pour in the homemade shrimp broth into the pot. 

Once the broth and guajillo sauce are ready, the soup takes minutes to cook. 

From here, it’s just a matter of adding all the seafood. 

• Add all the seafood to the pot. 
• Bring to a boil. 
• Serve immediately. 

Serve in a big bowl with a few spoonfuls of Mexican rice or just as is. 

Place another big bowl on the table for shells. 

It will get messy. Using your hands is expected. 

How Long Does Caldo de Siete Mares Last?

• In the fridge in an airtight container, siete mares lasts up to 4 days. 
• In the freezer in a sealable plastic bag, the soup lasts for up to 4 months. 

For a little spice, add sliced jalapenos. Drizzle with lime. 

Caldo de Siete Mares (or Mexican Seven Seas Soup) is a great way to warm up on cold nights. Full of flavor and soulful goodness.
