Is one cup of crisco equal to one cup of vegetable oil?

Ah, what a delightful question, friend. While both Crisco and vegetable oil can be used in baking, they are not always interchangeable in equal amounts. Crisco is solid at room temperature, so you would need to melt it before measuring it as a liquid like vegetable oil. It's always best to follow the recipe for the best results, but don't worry, you're doing great!
