Remove a pastry log from the refrigerator and roll it back and forth on a lightly floured surface until it's about an inch (25 mm) in diameter and 16 inches (41 cm) long. Cut it into scant 3/4-inch (18-mm) pieces. Place 1 piece pastry dough, cut side down, in each well of a nonstick 12-cup mini-muffin pan (2-by-5/8-inch [50-by-15-mm] size). ☞ TESTER TIP: If using classic egg tart tins, cut the dough into generous 1-inch (25-mm) pieces. Allow the dough pieces to soften for several minutes until pliable.
