Creamy Leek and Corn Orzo

Bring a medium pot of boiling water to a boil over medium heat. Season the water with salt, then add the orzo and cook to al dente . Drain, reserving the cooking water. In another pot of boiling water, over medium heat, blanch the leeks for 1 or 2 minutes, then remove and shock in a bowl of ice water. Drain and set aside. In a skillet, over low heat, melt the butter and add the corn and scraped milk from all 4 cobs. Cook for 1 minute and add about 1 cup reserved pasta cooking water. Bring to a simmer and cook until thick and reduced, about 10 minutes, stirring occasionally. Add more pasta cooking water if gets too dry. Add the blanched leeks and heat through, about 1 minute. Add the orzo and toss to combine. Season with salt, to taste. Transfer the corn and orzo to a serving bowl, garnish with parsley and serve immediately.
