Cream Custard Tarts

Ingredients

Directions

  1. In the bowl of a food processor fitted with a metal blade, pulse the flour, salt and sugar to combine.

  2. Add the butter and pulse until the flour resembles coarse, uneven cornmeal, about 10 1-second pulses.

  3. Drizzle 5 tablespoons of the ice water over the mixture.

  4. Pulse several times to work the water into the flour.

  5. Add the remaining water, 1 tablespoon at a time, and continue pulsing until the mixture develops small curds.

  6. Turn the dough out onto a work surface, shape it into a disc and cover with plastic wrap.

  7. Refrigerate for at least 1 hour.
