Even though fresh is always better, frozen peas work well in this recipe. You don't even have to change the cooking times.
Melt butter in a medium saucepan over medium heat; add peas, rind, and juice. Cook, stirring occasionally, 8 to 10 minutes or until thoroughly heated. Stir in fresh mint, salt, and pepper. Garnish, if desired.
*3 cups frozen early green peas may be substituted.
