- 1 large egg yolk
- 1 garlic clove, smashed, peeled, and trimmed
- 3 anchovy fillets, packed in oil, drained
- 1 tablespoon plus 1 1/2 teaspoons lemon juice
- 1 tablespoon plus 1 1/2 teaspoons red wine vinegar
- 1 tablespoon Dijon mustard
- 1 teaspoon dried oregano
- 1 teaspoon colatura (Italian fish sauce; optional)
- 1/4 teaspoon cayenne

- 1/2 cup freshly grated grana padano cheese
- Kosher salt
- Freshly ground black pepper
- 4 ounces country bread, crusts removed, bread torn into small pieces
- Two (5-ounce) containers baby kale
- Preheat oven to 400°F. Pulse egg yolk, garlic, anchovies, lemon juice, vinegar, mustard, oregano, colatura (if using), and cayenne in a food processor or blender until smooth. Combine canola oil and 1/2 cup olive oil in a measuring cup with spout. With the motor running, add blended oil in a very thin stream; purée until a creamy emulsion forms. Add cheese and pulse to combine. Season dressing with salt and pepper.
