To prepare a split pea chowder rice recipe, you'll first need to prepare your ingredients. Peel and slice the split Peas. Place the peeled and cut-up split pears in the bottom of the saucepan. Add the water and bring to boil. Reduce the heat to medium-low, cover, and simmer until tender, about 20 minutes. Remove the pan from heat and add the chopped parsley. Allow the mixture to sit for 5 to 10 minutes, then stir in 2 tablespoons butter and 1 teaspoon each kosher salt and ground black pepper. Serve with sour cream, if desired.
