shortening or butter

Shortening is a solid or semi-solid fat, traditionally made from animal lard or vegetable oils that have been hydrogenated to achieve a stable, shelf-stable consistency at room temperature. Butter, by contrast, is an emulsion of butterfat, milk solids, and water produced by churning cream or milk. Both ingredients are distinguished by their ability to create a tender crumb structure in baked goods through mechanical incorporation of air and the formation of fat layers that inhibit gluten development.

Shortening typically contains 100% fat with minimal water content, resulting in a neutral flavor and higher smoke point than butter. Butter contains approximately 80-82% butterfat, 15-17% water, and 1-2% milk solids, which contribute its characteristic rich, creamy flavor and lower smoke point (around 350°F/177°C). Common shortenings include vegetable shortening (made from soybean, cottonseed, or canola oils), palm shortening, and coconut oil-based alternatives.

Both shortening and butter are fundamental to pastry-making, where they create flaky pie crusts, tender biscuits, and light cakes. Butter is preferred in laminated doughs (croissants, puff pastry) and enriched breads due to its flavor contribution, though its water content requires careful technique. Shortening is favored in American pie crusts and some cakes where a neutral flavor is desired and moisture control is critical. In cookies, the choice between the two affects spread, texture, and browning. Butter excels in sauces, frosting, and sautéing for its emulsifying properties and flavor, while shortening serves decorative purposes or as a neutral cooking medium. Both are used in combination in many traditional recipes to balance tenderness, flavor, and workability.
