using sweet and white potatoes together

Aimee Mar 14, 2010 08:34 AM

I'm thinking of making some kind of gratin or casserole using the two together. Any suggestions? Thanks.

    You could make this marbleized root vegetable puree with just the white and sweet potatoes.

      Cook and mash them together with an assortment of spices. Here's a Spiced Mashed Potatoes I've made in the past:

      2 large russet potatoes
      2 large sweet potatoes
      1/4 cup butter, softened
      2 Tbsp honey
      3/4 tsp salt, or more to taste
      1/2 tsp ground ginger
      1/4 tsp ground cinnamon
      1/8 tsp nutmeg (or a couple of scrapes of freshly grated nutmeg)
      Couple dashes cayenne pepper

      Peel and cut russet potatoes into 2" chunks. Put into a pot of cold water and cook until potatoes are soft. Drain well. Meanwhile, peel and cut sweet potatoes into 2" chunks and steam for 20-30 minutes, or until soft. Combine with cooked russet potatoes.

      Mash potatoes with a potato masher or a hand mixer until fluffy. Add butter and mix well. Add honey and spices and mix well to blend.

        I like them mashed together in a ratio of about 2 parts white potatoes to 1 part sweet with lots of roasted garlic. Also works well with winter squash.

          i use them together in scalloped potatoes. it seems like the sweet potato cooked a little faster than the white so i slice them a thicker. also its good together as potato pancakes or latkes.

            This is wonderful if you want a really decadent dish. I use milk for some or all the cream. Also, make sure to dry the potatoes well or the dish may be liquidy.

                A favorite favorite of ours is from Sunset magazine years ago--

                Roasted Red and Yellows

                3 sweet potatoes or yams, scrub 'em, cut into chunks
                2 pounds red thin-sknned potatoes, scrubbed and chunked
                3 small to medium onions, skinned and quartered
                3 TBS olive oil
                salt and pepper
                sherry, balsamic, cider, or ? vinegar --optional

                Simply toss potatoes and onions in the olive oil, roast at 425F (shallow pan) until brown and tender. (About 1 hour) Season (sprinkle almost any vinegar on top if desired.) It all comes out sweet, and crispy on the outside, tender on the inside.

                  Check out Christina Mason's (culinspiration's) recipe for Chicken Shepherd's Pie with Spinach-Sweet Potato Mash. I haven't tried it but completely trust her recipes!

                    Thanks, Kattyeyes!

                    One of my favorite ways to enjoy white and sweets together is mashed with some butter, fresh rosemary, fresh sage, maybe a little parsley, and a dash each of cinnamon, cayenne, ginger, and nutmeg. Some roasted garlic is also good. Add milk as needed. So good!
