Identify your use case: flaky baking (pie crust/biscuits) vs. cooking/frying (browning and crisping).
Choose the closest match from the table: shortening for texture, butter or ghee for flavor, coconut oil for a solid swap, and duck/chicken fat for savory frying.
Apply the listed ratio (use weight for best consistency in baking).
If your substitute is softer than lard (like butter-ghee blends), chill the dough 20–30 minutes before baking for cleaner layers.
Taste and adjust: if flavor turns too rich or nutty, reduce the amount slightly next time or balance with salt/acid in the dough.
