Both will do. You can fry steak without oil. Because the steak itself contains grease, you just need to heat the pot, add the steak and fry it slowly. When the steak sizzles in the pot, there will be a lot of fat in the pot, so the fat content of the steak fried with its own fat is even lower. Don't worry at all during the fat reduction period, you can rest assured to eat.

Identification method of beef:

Take a look and see if there are any red spots on the skin. Those without red spots are good meat, and those with red spots are bad meat. Look at the muscles, the fresh meat is shiny, the red is even, and the inferior meat is slightly black; Look at the fat, the fat of fresh meat is white or light yellow, the fat of inferior meat lacks luster, and the fat of deteriorated meat is green.

Second, fresh meat has a normal smell, while inferior meat has an ammonia smell or a sour taste.

Three touches: First, it feels elastic, fresh meat is elastic, and the depression immediately recovers after finger pressing, while inferior meat has poor elasticity, and the depression recovers slowly or even cannot recover after finger pressing, and deteriorated meat is inelastic; Second, feel the viscosity. The surface of fresh meat is slightly dry or wet and does not stick to hands. The surface of sub-fresh meat is dry or sticky, and the new cut surface is wet and sticky. Deteriorated meat sticks to hands seriously and the surface is extremely dry. However, some meat with serious water injection does not stick to hands at all, but it can be seen that the appearance is wet and unstable.
