Garlic-infused oil (Best Option)
1 teaspoon per 1 cup of flourGarlic-infused oil works well because it delivers the garlic flavor in a fat medium, which integrates smoothly into dough without affecting hydration levels. The oil also helps with dough elasticity and frying performance.
To use successfully, ensure the oil is well strained to avoid garlic pieces that could burn during frying. Adjust other fats slightly if needed to maintain dough consistency.
Compared to fresh garlic, this substitute provides a subtler, more even garlic flavor that complements doughnuts without overpowering or altering texture significantly.
