Maybe the most sophisticated yet simple cookies you'll get your hands on this season. They are sweet but savory, crumbly but firm, and just perfect for a holiday gathering or party. And they freeze wonderfully, of course.
In a bowl mix soft 6 tablespoons unsalted butter with 1 cup powdered sugar.
Add 1 egg yolk and mix well.
Add 1 teaspoon sea salt, 1 tablespoon olive oil, 1 teaspoon sesame oil and 3 tablespoons sesame seeds and mix everything until combined.
Add 1 cup all-purpose flour and combine until no dry spots remain.
Put this mixture on a piece of plastic wrap, making a cylinder or log parallel to the counter, leaving a border of about 2 inches.
Start by folding the side close to you over the log of cookie mixture, as you would a cinnamon roll. Then go back and forth so the plastic clings and encloses the whole log.
Grab the platic by both ends and roll, closing the ends. The plastic will probably bulge a bit. Prick it lightly with a fork once or twice to let the air out. This will ensure the dough remains soft and doesn't dry out.
Refrigerate for 1 hour or freeze for up to 1 month.
When ready to bake, preheat oven to 350°F (180°C).
Line a cookie sheet with parchment paper.
Take out the cookie dough and cut circles about ⅓ inch.
Arrange on prepared sheets and bake for 12 to 15 minutes, until they are dried, a bit crackled and starting to turn golden.
Let cool completely on a wire rack and keep in closed tins or cookie jars.
Notes
Freezing: you can make a large batch and freeze the cylinders.
