Think of them as teammates, not rivals. One is your workhorse, the other is your show pony. Vegetable oil is for the Tuesday night stir-fry when you just need dinner done. Olive oil is for the Friday night dinner party when you want to feel fancy and taste that sun-drenched olive orchard.
Don’t stress when you accidentally swap them—the world won’t end. But now you know: vegetable oil and olive oil are not the same, and that’s totally fine. They’re just different tools for different meals, and your kitchen is richer for having both.
