If you soak it in lemon water and sprinkle some starch before grilling, the meat will be more tender. Seafood: All kinds are available, but be sure to choose fresh ones. Fresh seafood has dense and elastic meat. The seafood taken out of the refrigerator should not be marinated for more than 30 minutes before grilling. When grilling squid rolls, brush a thin layer of egg yolk on top to make the color more beautiful and taste better. Vegetables and fruits: Mainly roots, mushrooms, fruits and vegetables with less juice and hard texture, such as corn, green peppers, pineapples, bananas, etc. 4. Once the food is put on the grill, impatient people are always worried that it will burn and keep turning it over and over. In fact, this will prolong the cooking time, destroy the protein, and cause the meat to become hard. When flipping food, the food must be heated to a certain level before it can be easily turned over. If part of the food sticks to the rack after turning it over, it means that the protein has not been completely heated. Hard pulling will only tear the protein fibers, and if it is fish, it will cause peeling. 5. The longer the food is grilled, the greater the loss of water and oil will be, and the drier the taste will be. Therefore, during the barbecue process, you should brush an appropriate amount of barbecue sauce on the food to keep the food moist and increase the flavor. However, be careful not to brush too much at one time, which will cause the food to be too salty. 6. For those who have a certain basic knowledge of barbecue, making authentic diamond-shaped grill marks can definitely improve the barbecue technology. In fact, it is not difficult to bake diamond-shaped grill marks. First, the charcoal temperature must be hot enough, and then place the food on the grill at an angle of 30 degrees.

Follow the same steps to sear the other side of the food with grill marks. Make your own delicious barbecue sauce.
