So, what's the science behind cooking steak in butter versus oil? Well, it all comes down to the smoke point - the temperature at which a fat starts to break down and smoke. Butter has a relatively low smoke point, which means it can start to burn and smoke if it gets too hot. On the other hand, oil has a much higher smoke point, making it a great choice for high-heat cooking.
But, here's the thing - smoke point isn't the only thing to consider when cooking steak. The type of fat you use can also affect the flavor and texture of the steak. Butter, for example, contains lactones, which are compounds that add a rich, creamy flavor to the steak. Oil, on the other hand, can add a lighter, more neutral flavor.

So, what's the verdict? Is it better to cook steak in butter or oil? Well, the answer is - it depends. If you want a rich, indulgent steak with a deep, creamy flavor, then butter is the way to go. But, if you want a lighter, crisper steak with a nice crust, then oil might be the better choice.
