TRADITIONAL BRITISH DISH RECIPES

Steps:

• Preheat the oven to 350 degrees F (175 degrees C).
• Place potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain and let cool.
• Combine milk, bay leaf, and nutmeg in a large pan and bring to a gentle simmer over medium-low heat. Add cod and poach until flaky, about 5 minutes. Use a slotted spoon to transfer cod onto a plate; reserve poaching liquid. Use a fork to flake fish into bite-sized pieces.
• Mash potatoes in a large bowl. Mix in 3 tablespoons butter and 2 tablespoons poaching liquid until potatoes are fairly stiff and not too runny.
• Heat 1 tablespoon butter in a skillet over medium heat and stir in leek. Cook and stir until softened and translucent, about 5 minutes. Set aside.
• Melt remaining 1/4 cup butter over medium heat in a large, deep skillet until it just stops bubbling. Add flour and stir roux continuously for 1 minute. Slowly pour in remaining poaching liquid, stirring continuously, to make base of sauce. Add 1/2 the sharp Cheddar cheese and stir until melted. Fold in flaked cod, leek, and peas. Season with salt and pepper.
• Place fish mixture in an oven-proof dish; press boiled eggs gently into the filling across the surface. Cover with a thick layer of mashed potatoes. Sprinkle with remaining Cheddar cheese.
• Bake in the preheated oven until top is starting to brown, about 30 minutes. Serve immediately.

Steps:

• Put the split green peas in a large pot with the baking soda and enough water to cover the peas four times over. Cover and allow to rehydrate in the fridge overnight. 
• Drain the peas in a colander and rinse with cold water to remove any lingering baking soda. 
• Return the peas to the pan and cover with cold water by 1/2-inch. Add some salt, bring to a boil and then reduce the heat to a simmer. During the simmering, discard any pea foam that forms on top using a slotted spoon. The peas are done cooking once they just lose their bite, 30 to 40 minutes. Overcooking results in soup, which isn't what we're going for. 
• Remove from the heat, add the butter and stir to fully incorporate. Taste and add more salt if required. 
• Serve immediately with fish and chips, or cool and store for up to 3 days.
