Read All Recipes All The Way Through Before You Start To Cook
The number one killer of all recipes world wide. It's like getting in a car and driving away having never driven a car, or maybe even seen a car before.
Keep half of the grill cooler. Whether over coals or gas, if you have high heat on one side you can get a good sear and crust, and then move product to the cooler side to continue cooking without burning it. You also have a safe space in case you get too much flare up and you start to panic.
Use tongs over something like a meat fork to move meats on the grill. Poking holes in meat drains the coveted juices
Try not to touch or move things on the grill too much. It is natural to want to play with everything, I know it's fun, but you get the best grill marks and char crust if you just let it cook.
If the meat or any product sticks to the grill grate, do not pull at it until it comes loss. When the meat sticks it is still cooking, and it will become loose when it is ready to be flipped. If you have to pry it off try to use a spatula instead of tugging at it with a tongs. Having a hot grill which has been well scraped will keep foods from sticking in most cases
Roasting & Ovens
Ovens rely on radiant heat which circulates around a product to heat it, which means that the more room for air flow a product has around it the more evenly and thoroughly it will cook. So for longer cooking with more even cooking, like a roast, us a rack in the middle of the oven to promote air flow around it.
For the best results with browning an item in the oven use a rack at the top of the oven, where the hottest air rises and will brown the outside best
For the best results with browning the bottom of a product, like a pizza, us a rack at the bottom of the oven, because most ovens heat from the bottom the most direct heat will come from the lower area
