Q: I was making brownies from a mix that called for vegetable oil. The only oil I had was olive oil. The brownies came out OK, but I wondered if there are times when you shouldn’t use olive oil.
A: Olive oil is high in monounsaturated fat and is believed to have other health benefits, including antioxidants. Olive oil is also sometimes used as a substitute for butter in baking, particularly for vegans. Still, there are differences between olive and vegetable oil in cooking:
Taste. There are rustic-style cakes that use olive oil, but the flavor of olive oil is distinctive. It might not work in all sweet dishes.
Price. Depending on the quality, olive oil generally costs more than vegetable oil.
