Almost anyone who has ever entered a kitchen should know this, but I still catch tons of people screwing it up. As a general rule, more heat so that it will cook faster is NOT the way to cook almost anything (though some people grilling on open flame outdoors may disagree). Almost nothing cooks better fast. Low, even heat for everything from browning meat to cooking eggs. It's always better to err on the side of caution and increase it from there.
