Why we cook food in oil

Summary by Krater

The video demonstrates how cooking oils and liquids act as a thermal interface between a hot pan and food like Brussels sprouts, broccoli, bread, steak, and chicken. It concludes that while oil helps brown food faster and more evenly by filling gaps, its main benefit is facilitating heat transfer rather than just preventing sticking.

From the video

Answers: Why do recipes start with putting oil in a pan?

• Thermal interface in cooking
• Oil vs water in sautéing
• How cooking oils affect browning
• Meat searing with and without oil

Ingredients

• Brussels sprouts
• olive oil
• broccoli
• water
• sirloin steak
• chicken thigh
• pizza dough
• mixed vegetables

What it concludes

• Oil serves as a thermal interface that conducts heat from the pan into parts of the food that are not touching the metal.
• Water has a lower boiling temperature and evaporates before reaching the high temperatures required for Maillard browning.
• Oil helps meat brown faster and more evenly because it acts as an effective thermal interface compared to dry cooking.
• Cooking oil facilitates the absorption of fat-soluble vitamins in the body.
