Stepwise Method: “Sancocho” de Mariscos (Shellfish Stew)

Step 1: Prepare the Ingredients
Begin by gathering and prepping all your ingredients. Peel and cube the potatoes and auyama, slice the plantains, and crush the garlic. Ensure your shrimp are peeled and deveined.
Step 2: Sauté the Aromatics
In a large pot, heat a drizzle of oil over medium heat. Add the crushed garlic, oregano, and thyme. Sauté for about 2-3 minutes until fragrant and the garlic is golden.
Step 3: Add Vegetables
Next, add the cubed auyama, potatoes, and sliced plantains to the pot. Stir well to coat with the garlic mixture and sauté for another 5 minutes.
Step 4: Pour in the Broth
Add enough water to cover the vegetables, about 6-8 cups, and bring to a boil. Once boiling, reduce the heat and let it simmer for about 20 minutes, or until the vegetables are tender.
Step 5: Incorporate the Shellfish
Once the vegetables are tender, gently add the shrimp and assorted shellfish. Stir in the lime juice, salt, and pepper. Cook for an additional 5-7 minutes until the shrimp turn pink and the shellfish open up.
