Yukon Gold Sweet Potato Mash Recipes

MARBLED MASHED SWEET POTATOES

Steps:

• Put the potatoes and sweet potatoes in a large saucepan and cover with cold water by 1 inch. Add a generous pinch of salt, bring to a simmer and cook until the potatoes are easily pierced with a knife, 35 to 40 minutes. Drain and let cool slightly. Peel the Yukon gold potatoes and transfer to a medium bowl. Peel the sweet potatoes and transfer to a separate bowl.
• Divide the butter between the 2 bowls. Add the heavy cream and sour cream to the Yukon gold potatoes and mash well with a potato masher; season with salt and black pepper. Add the brown sugar and cayenne to the bowl with the sweet potatoes and mash well; season with salt and black pepper.
• Dollop the potatoes and sweet potatoes into a warmed serving dish and swirl using a large spoon. (The potatoes can be made up to 2 hours ahead; set aside in a baking dish. Reheat, covered, at 350 degrees F, 15 to 20 minutes.)

YUKON GOLD MASHED POTATOES

Steps:

• Peel and cut potatoes into a ½-inch dice. To prevent potatoes from wobbling as you dice, cut a flat base for the potato to rest on as you make your slices. (Note: Potatoes can be peeled and diced 1 day in advance. Store completely submerged in cold water in the refrigerator, changing the water every few hours to prevent browning.) Place potatoes in a pot filled with cold salted water (as "salty as the sea"). Bring to a boil over high heat, 6-8 minutes. Once boiling, reduce to a simmer and cook until fork-tender but not falling apart, 15-20 minutes.
• Drain the potatoes in a colander, then add back to the pot. Turn heat to low and let the potatoes release additional moisture, 1-2 minutes. Turn off the heat.Transfer potatoes to a large bowl. Work all the potatoes through the ricer and back into the pot.
• With the pot over low heat, gently fold in butter and sour cream, mixing just enough to melt and incorporate; overmixing will result in a gluey texture. Add the milk a splash at a time, gently mixing to incorporate; repeat until you reach your desired consistency. (You may have milk left over.) Season to taste with salt and pepper. Transfer to serving bowl; garnish with extra butter and/or freshly chopped chives, optional. Serve immediately.
