1/4 cup finely grated Parmesan cheese, plus extra for sprinkling over salad
Directions
Preheat the oven to 400 F.
To roast the garlic: Remove the outer layers from the head of garlic so the individual cloves are exposed. Chop off the top 1/4 inch of the head so you can see the raw cloves within their skins. Place on a 9×13 sheet of foil, drizzle with olive oil, and wrap so the packet is tightly sealed. Roast in the oven for 30 minutes, until the cloves are soft to the touch. Remove from the foil packet and allow to cool.
For the dressing: When cool enough to touch, squeeze the cloves out of their skins and add to a food processor. Puree the garlic along with the lemon juice, mustard, salt, and 1/3 cup olive oil. Taste and add more oil as necessary to reach the consistency you like. (This should be a thick dressing, with a punch of acidity.) Store in an airtight container for up to 2 weeks.
For the salad: Remove the thick stalks from the center of the kale. Pile the leaves on top of one another and roll together into a cigar. Cut the kale into thin ribbons.
In a large mixing bowl, toss the kale together with the dressing. Add the Parmesan cheese and toss again.
