Canola Oil (Best Option)
1:1 (1 cup canola oil per 1 cup vegetable oil)Canola oil is chemically similar to vegetable oil with a neutral taste and high smoke point, making it ideal for frying doughnuts. Its fatty acid profile supports proper moisture retention and texture development in the dough.
When substituting, use the same amount as vegetable oil. Ensure the oil is fresh to avoid off-flavors. Monitor frying temperature to prevent oil degradation.
The final doughnuts will have comparable texture, crispness, and flavor to those made with vegetable oil, making it an excellent direct substitute.
