1/4 cup canola oil
1/4 cup extra-virgin olive oil
6 oil-packed anchovies
4 large cloves garlic, smashed and peeled
1 large egg yolk
2 Tbs. fresh lemon juice
2 tsp. Dijon mustard
1 tsp. finely grated lemon zest
1/2 tsp. Worcestershire sauce
1/4 tsp. kosher salt
1/4 tsp. freshly ground black pepper
1 oz. Parmigiano-Reggiano, finely grated (1/2 cup)
In a liquid measuring cup, combine the canola and olive oils. Put the remaining dressing ingredients except the Parmigiano in a blender and blend until thoroughly combined. With the motor running on medium high, carefully pour in the oils in a slow, steady stream. The dressing will emulsify as soon as all of the oil is incorporated. Stop the motor, add the Parmigiano, and quickly blend to combine. You can store the dressing, tightly covered, in the refrigerator for up to 3 days.
