It’s essential to pre-heat your grill if you want to succeed in grilling. You are practically endangering all of your meals if you skip this crucial step. Two things support this. First off, your meal will wind up taking an unnecessarily long time because your grill won’t achieve the ideal cooking temperature.
Second, say goodbye to your delicious, crisscross grilled-marked steak if you place it on a cool or lukewarm surface. Putting raw food on cool grates will all but guarantee that you won’t get tasty sear marks. These marks are where the sugars in your meal caramelize to give it that smoky, wonderful flavor we all adore from grilled food.
Not to mention that your food will stick to the grate if your grill is not properly preheated as the pores of the metal hasn’t fully expanded and closed up. Gravity causes your meats to sink into the open pores, as the metal expands, the pores close up which bites onto your food causing it to stick.
Thirdly, it drys out anything that was previously stuck on the grill (assuming you didn’t preheat the grill properly) which will make it easy to brush off with a wire brush.
So the next time you light up your grill, remember to give your grill at least 10-15 minutes to preheat before slapping on those meats.
