โญ Shortening (Best Dairy-Free Option)
1:1 by volume (e.g., 1/2 cup shortening per 1/2 cup butter)Shortening is 100% fat and solid at room temperature, which helps create the flaky layers typical of biscuits by coating flour proteins and preventing gluten overdevelopment. Its high melting point allows it to remain solid during mixing and form pockets of fat that steam during baking.
To use shortening successfully, ensure it is cold and cut into the flour similarly to butter. Avoid overmixing to maintain the desired flakiness.
Compared to butter, biscuits made with shortening may have a slightly less rich flavor but will have comparable texture and rise, making it an excellent substitute when butter is unavailable.
