Here’s the fun part: they behave totally differently in heat. Vegetable oil is liquid at room temperature, so it spreads moisture evenly through batters. That’s why your banana bread stays soft and doesn’t turn into a brick by day two.
Shortening acts like a butter impersonator but stays solid until it meets the oven. That solid fat creates tiny pockets in dough—perfect for that crisp, flaky magic in a pie crust. It’s like building little air pillows for your baked goods.
Remember that time you made pancakes and they came out rubbery? You probably used too much oil. Or that time your cookies spread into one giant blob? That was too much butter, not enough shortening. Balance is key.
When Life Gives You Frying
For frying, oil is your best champion. It heats up fast and evenly, giving you golden french fries or crispy chicken without a greasy mess. Just don’t reuse it too many times—your kitchen will start smelling like a diner from 1985.
Shortening used to be the king of frying, especially for doughnuts. But let’s be real: nobody wants a doughnut that leaves a waxy film on your lips. So for most everyday frying, go with a neutral oil like canola or grapeseed.
