2 large egg yolks
1 1/2 teaspoons Dijon mustard
2 tablespoons distilled white vinegar
2 cups canola oil
If the mayonnaise breaks, transfer the broken mixture to a spouted measuring cup. Add 1 egg yolk and 2 tablespoons water to a clean food processor and process to combine. With the machine running, slowly drizzle in the broken mayo as before.
