Distilled white vinegar can be used in cooking. However, other vinegars, such as balsamic vinegar and apple cider vinegar, have more flavor.
Distilled white vinegar is made from grains. Some name brands, such as Heinz, make their distilled white vinegar exclusively from corn. According to How Stuff Works, corn is converted into alcohol through yeast, and then the alcohol is converted into vinegar. Vinegar is a weak acid, which is why it's also used as a household cleaner. Nonetheless, it has been used in food preparation for a very long time. In fact, Heinz has been making vinegar for over 140 years. In cooking, vinegar can be used to tenderize meat, make pickles, poach eggs or even create buttermilk.
