When I said I was making a pea sauce, my roommates said "What!?"
Then I explained that I was going to use frozen peas, not urine, to make a sauce for a cod fillet. Although they were still skeptical, my roommates were at least satisfied that I was making something edible.

Once it was pureed, the sauce had a nice creamy consistency and didn't immediately seem like something that had been made with peas. It tasted a little sweet and a little spicy, with a fresh tang. The cod I cooked in it was moist and tender, and went well with the sauce. All in all, the meal was a pleasant surprise. Using the simplest, most easily obtainable ingredients, I was able to make something that tasted special.

*serves 1
1 frozen cod fillet
1/2 cup frozen green peas
1 tbsp lemon juice
1 cup water
1/2 tsp ground cayenne pepper
1/2 tsp ground mustard
a pinch of salt
pepper to taste

Put the frozen cod, peas, lemon juice, and water in a small skillet over high heat. Bring the water to a boil, then reduce heat to simmer. Stir in the cayenne pepper and mustard. Cook the cod for about 10 minutes on each side, until it is fully cooked. Remove the cod to a plate. The peas should have softened during the 20 minutes of cooking. Press the peas and liquid through a mesh strainer into a bowl, then pour it back into the skillet and raise heat to high to bring the sauce to a boil. Add a pinch of salt, if desired.  When the sauce is reduced with a creamy consistency, pour it over the cod on the plate. Season with black pepper, and enjoy immediately.
