Canola Oil (Best Option)
1:1 (1 tablespoon canola oil per 1 tablespoon olive oil)Canola oil is a neutral-flavored oil with a similar fatty acid profile to olive oil, making it an excellent substitute in biscuits. It provides the necessary fat to coat flour proteins, limiting gluten development and resulting in tender, flaky biscuits.
When using canola oil, ensure it is fresh to avoid off-flavors. Because it is liquid at room temperature, it blends easily into biscuit dough without altering consistency.
Compared to olive oil, canola oil produces biscuits with a slightly lighter flavor profile but similar texture and moisture retention.
