Butter in steak has two purposes:
1. Oil used for frying steak
When the marinated steak is cooked in a non-stick pan, there is no need to add oil. But in other pots, meat will stick to the pot, so use oil. Generally speaking, when frying steak with olive oil, you can brush the oil on the steak or add butter to melt it with warm fire during the curing process. Butter can also be seasoned in the process of frying steak.
What kind of butter is suitable for frying steak
If you need butter to fry steak, animal butter is the best choice, with better natural taste and better flavor enhancement effect. It is best not to eat vegetable butter often. It is hydrogenated vegetable oil. Artificial hydrogenation will form trans fatty acids in oil. Long-term consumption will cause cancer, so try not to use vegetable butter. Butter is rich in flavor and fragrance, and it also has a unique taste when frying steak.
The reason why butter is chosen is that when you fry steak with butter, novices are not easy to get burnt, and they can master the heat skillfully. The fried steak will be tender, and if it is salad oil, it will be very fried. As for salt or not, it depends on your other ingredients. If the ingredients are high in salt, such as black pepper sauce, there is no need to put salt.
You don't have to fry the steak.
People who like the original flavor of steak can marinate the steak without adding butter or olive oil, and only need to apply a little olive oil when marinating. Butter has a certain taste. Although it can be used to fry steak, its own flavor will remain on the steak, so the fried steak is not so original. Therefore, if the meat quality of steak is good, I suggest you don't use butter.
