things people ask

• How much powdered sugar dusts a single brownie?
  A quarter to half a teaspoon (roughly 0.5-1 g) tapped through a fine sieve covers a 2-inch brownie square evenly. More than that and the sugar starts to absorb moisture from the brownie surface within an hour, going patchy and translucent. Dust just before serving rather than ahead — humidity will defeat even a perfect dusting if it sits.
• Is a teaspoon enough to glaze one cookie?
  Yes, for thumbprint or shortbread cookies. One teaspoon (2.35 g) whisked with a few drops of milk or lemon juice makes enough glaze for a single cookie's surface. Scale up linearly: a dozen cookies needs about 12 teaspoons, or roughly a quarter cup of sifted sugar plus a tablespoon of liquid.
• Why do bakers macerate strawberries with powdered sugar instead of granulated?
  Granulated draws juice fast but leaves visible crystals on the fruit; powdered dissolves almost instantly and gives a glossy coat. One teaspoon (2.35 g) per cup of sliced berries is enough for a light maceration meant to be eaten within thirty minutes. For longer maceration, the cornstarch in powdered sugar can thicken the released juices into a syrup, which some cooks like and others don't.
