8ozunsalted Irish butter, softened and cut into chunks(225 grams)
1 ½cupsall-purpose flour, bleached or soft like White Lily(200 grams)
⅔cupconfectioners' sugar(80 grams)
½cupcornstarch, weigh or measure with a light hand(64 grams)
¾teaspoonkosher salt (omit if using salted butter)
Instructions
Brown half the butter (114 grams) over the stove, then pour into a small bowl and let cool. Throw it in the freezer if you're in a hurry and let cool just until it is sludgy.
Mix together the flour, confectioners' sugar, cornstarch and salt (if using) and put in the food processor.
Cut remaining butter into chunks and add to food processor. Pulse until crumbly. Add the browned butter and pulse until dough comes together.
Turn dough onto a parchment or wax paper lined counter and push it together into a mass. Roll it out and chill the rolled out dough for about 20 minutes. Punch out shapes with a 2-inch round or slightly smaller cutter.
Bake dough rounds at 350F for about 12 minutes or until the edges are lightly browned. Let cool on the baking sheet, as they will be very delicate.
