Sweet Potato Fries with Garlicky Mayonnaise

For the Fries:
Two sweet potatoes, peeled
1 tablespoon olive oil
1 half tablespoon canola oil
Kosher salt

Preheat the oven to 450. Cut the sweet potatoes into thin fry shapes (I cut off each side, leaving a rectangle and then slice the cube into 1/4 inch slices.) Place on a roasting pan. Toss with the oil and salt, and bake for 30-35 minutes or until crispy, tossing occasionally.

Mayonnaise:
1 clove garlic, crushed
1/2 tbsp lemon juice
1/4 tsp salt
1/4 tsp dijon mustard
1 egg yolk
1 tsp white wine vinegar
Freshly ground black pepper
1/2 cup vegetable oil
1/4 cup olive oil

Heat the vegetable oil until very hot. Add the garlic and remove from heat. Let steep for at least 10 minutes, then remove the garlic and let cool.

Whisk together the lemon juice, salt, mustard, egg yolk, vinegar and pepper. Combine the two oils, then add the oil drop by drop, whisking continuously. Once the mayonnaise starts to emulsify, add the oil more rapidly.
