Shell the peas if using fresh peas, if using frozen defrost fully before cooking. Bring the water to a rapid boil. Stir in the salt and add the peas. Boil the peas for 1 minute or until they are cooked. Drain the peas when done and add peas to a wide skillet over high heat. Toss in pan until fully dry. Add butter and salt and pepper to taste. Add any optional additions if you choose, and combine.
