1-1/2 lbs jumbo shrimp in shells
1/4 cup olive oil
1 cup chopped onion
1 lb. whitefish heads and trimmings
2 cloves garlic, minced
1 large tomato, chopped
1 tsp. chopped chiles
1/2 tsp oregano
2 tsp salt

2 potatoes, halved lengthwise
1 lb. green peas
1/2 cup long grain rice

Clean the shrimp, saving shells. In a casserole, heat the oil. Add onion, shrimp shells, fish trimmings, and garlic. Cook, stirring, for 6 minutes.

Stir in tomato, chile, oregano, salt and pepper. Cook 3 minutes. Add water and diced potatoes. Cover and simmer 30 minutes, or until potatoes are tender. Pour into a sieve over a bowl and force through with a spoon. Discard the pulp. Return puree to casserole, bring to a boil and add potato halves and rice. Simmer for 25 minutes.

Add peas and corn. Simmer, covered, for 5 minutes. Drop in shrimp and cook 5 minutes. Meanwhile, beat eggs. Pour eggs slowly into the stew. Add milk and simmer to heat through. Season and sprinkle with parsley.
