  1. Preheat the oven to 350°F, and line two baking sheets with parchment.
  2. Put the pearl sugar in a small bowl. Wrap the base of a flat-bottomed jar or glass in plastic wrap.
  3. In a large mixing bowl, beat the butter, sugar, and salt together at medium speed until smooth and creamy, about 3 minutes. Mix in the egg white, followed by the vanilla.
  4. Add the flour in three additions, beating only until it's almost incorporated each time before adding more. Scrape down the sides and bottom of the bowl as you go.
  5. Scoop the dough by the heaping teaspoon and roll into balls. Roll each ball in pearl sugar and place on the baking sheet, 2" apart.

  7. Gently press each cookie down with the plastic-wrapped jar to flatten slightly.
