shortening to grease the dish

Shortening is a solid or semi-solid fat used primarily for baking and greasing, derived from vegetable oils, animal fats, or a combination thereof through hydrogenation or other processing methods. Common forms include vegetable shortening (hydrogenated soybean, cottonseed, or palm oil) and animal-based shortenings (lard, beef tallow). The term "shortening" refers to its function in baking—it shortens gluten strands, creating tender, crumbly textures in pastries and baked goods. Modern shortening is typically odorless, flavorless, and engineered to remain stable at room temperature with a high melting point, making it ideal for pie crusts, biscuits, and greasing cookware.\n\nVegetable shortening became commercially prominent in the early 20th century and has largely replaced lard in Western kitchens, though lard remains preferred in many traditional cuisines. The consistency of shortening (firm at room temperature but pliable when worked) distinguishes it from oils and butter.

Shortening is employed in baking to create tender, flaky pastries, pie crusts, biscuits, and cakes by preventing gluten development and distributing moisture evenly throughout the dough. Its high smoke point (approximately 350–375°F / 175–190°C) makes it suitable for shallow frying and sautéing, though it is less commonly used for this purpose than oil. For greasing baking dishes, shortening prevents sticking and creates an even, neutral coating without imparting flavor. It is also used in traditional cuisines for frying tortillas, empanadas, and other fried breads. Many bakers prefer shortening over butter for achieving maximum flakiness in pie dough and laminated doughs because its higher melting point and neutral flavor produce superior texture.
