You may never return to regular mayonnaise again. This unintentionally dairy- and egg-free "mayo" is made simply from silky smooth avocados, fiery ginger, a teensy bit of garlic and zippy limes, with an optional extra kick from chile. Slather it into a steak sandwich or dollop on the side of these addictive sweet potato fries.

Prep Time
Cook Time
  • 4 sweet potatoes (about 1 3/4 pounds)
  • 3 tablespoons olive oil
  • 3 tablespoons polenta
  • 1 teaspoon paprika
  • sea salt
  • 1 large ripe avocado
  • 1 1/2 ounces ginger
  • 1/2 small garlic clove
  • Juice and zest of 1 lime (you need about 3 tablespoons juice)
  • Dash of Tabasco (optional)
  • 1 tablespoon olive oil
  1. Preheat the oven to 400°F. Wash the sweet potatoes in cold water and dry thoroughly with a clean kitchen towel — there’s no need to peel them. Then cut lengthwise into long, ½-inch-wide fries. Transfer to a large bowl. Add the oil and toss together to coat. Then add the polenta, paprika, and a good pinch of salt. Mix well to evenly coat.
  2. Spread the fries between two large roasting pans. They need as much space as possible, so they should be in a single layer. Bake for 35 to 40 minutes until tender and crisp.
  3. Meanwhile, make the “mayo” dip. Place the avocado flesh in a food processor. Add the grated ginger, garlic, lime juice and zest, Tabasco (if using), olive oil, 1 tablespoon of cold water, and a large pinch of salt. Pulse until smooth. Transfer to a small dish and serve with the warm, crunchy sweet potato fries.
