Ingredients
- 1 lb russet potatoes
- 1 lb cod fillet
- 1 Tbsp spicy ketchup or chili sauce
- A handful of minced fresh parsley
- Juice of 1/2 lemon
- 2 large eggs, beaten
- 1/2 tsp salt
- 1/2 tsp fresh ground black pepper
- 32 Ritz crackers, finely crushed
- Several Tbsp vegetable oil for frying
- Sliced green onion (for garnish)
- Chopped parsley (for garnish)
- For the Tartar Sauce:
- 1 pasteurized egg, at room temperature
- 1 cup vegetable oil, at room temperature
- 1 tsp grainy Dijon mustard
- Juice of 1/2 lemon
- 2 tsp capers
- 1/2 cup dill pickles, chopped
- 1/4 tsp salt
- Fresh cracked pepper to taste
Instructions
- Step 1: Peel and chop the russet potatoes into large chunks. Place in a saucepan, cover with cold water, add 2 teaspoons of salt, and bring to a boil. Cook until soft and tender, about 15-20 minutes.
- Step 2: Place the cod fillet in a shallow sauté pan and cover with cold water. Bring to a gentle boil, then cover the pan and turn off the heat. Let it poach for about 10-15 minutes. Drain excess water.
- Step 3: Drain the cooked potatoes and transfer to a large mixing bowl. Mash using the back of a fork, leaving some texture for bite.
- Step 4: Add spicy ketchup, minced parsley, lemon juice, beaten eggs, salt, and pepper to the potatoes. Stir briefly to combine. Gently fold in the poached cod, breaking it apart evenly.
- Step 5: Using a 1/3 cup measure, scoop and form the mixture into patties. If needed, flour your hands to prevent sticking.
- Step 6: Roll each patty in the finely crushed Ritz crackers until fully coated. Place patties on a platter and refrigerate briefly if desired.
- Step 7: Heat vegetable oil in a skillet over medium heat. Carefully add patties and fry about 5 minutes on each side, until golden brown and crispy. Handle gently to avoid breaking.
- Step 8: Serve immediately on a bed of greens, garnished with sliced green onion and chopped parsley. Offer tartar sauce and lemon wedges on the side.
- Step 9: To make tartar sauce, combine pasteurized egg, vegetable oil, Dijon mustard, lemon juice, capers, chopped dill pickles, salt, and pepper in a jar. Blend with an immersion blender until thickened. Refrigerate until ready to serve.
