Ingredients

1 small head garlic 

2 cups plus 2 teaspoons extra-virgin olive oil 

4 large egg yolks, room temperature 

3/4 teaspoon coarse salt 

2 tablespoons plus 2 teaspoons fresh lemon juice 

2 tablespoons heavy cream 

Preparation

Preheat oven to 375. Place garlic on a piece of parchment set over a piece of foil, and drizzle with 2 teaspoons oil. Fold and crimp to enclose. Roast until tender, about 1 hour. When cool enough to handle, squeeze cloves from skins.

Process garlic, egg yolks, and salt in a food processor until combined. With machine running, gradually add remaining 2 cups oil, drop by drop at first and then in a slow, steady stream, until emulsified. Stir in lemon juice and cream. Aioli can be refrigerated, covered, for up to 2 days; do not leave unrefrigerated for longer than 1 hour.
