Okinawa Sweet Potatoes

Lisa Romerein
Total time 1 hr
Yield Makes 10 to 12 servings
Sweet potatoes are a very old food in Hawaii, thought to have been transported to the islands by the earliest Polynesian settlers. Okinawa sweet potatoes, so named because they're native to the Japanese island of Okinawa, turn a stunning deep purple when cooked and have a dense, starchy texture.

Ingredients

  • 4 pounds Okinawa (purple) sweet potatoes or white sweet potatoes, scrubbed
  • 2 limes

How to Make It

  1. Bring a large pot of water to a boil over high heat. Prick sweet potatoes with a fork and boil until tender when pierced, 30 to 35 minutes. Drain.

  2. While potatoes are boiling, grate zest from limes and set aside; then squeeze juice from limes and set aside.

  3. When potatoes are cool enough to handle, peel and slice into 1/2-in.-thick slices. Arrange on a platter, cover with foil, and put in a 200° oven to keep warm.

  4. Melt butter in a small saucepan over medium heat until foaming. Stir in zest and cook until fragrant, 1 minute. Remove from heat and stir in lime juice. Drizzle lime butter over potatoes and sprinkle with salt.
