If your tortillas don't sizzle quietly when they hit the pan, it isn't hot enough. If the residual flour (from rolling) smokes, your heat is too high. Don't be afraid to adjust your temperature or time left in the pan, but the best ones will come from a pan that's hot enough to allow the shortest cooking time on each side.
Making your own tortillas isn't hard, but it might take you a few tries to get your groove on. Having friends over for a taco or burrito night? Put them to work making their own tortillas while you're getting conversation started. What better way to get together than joining in to make your own meal from fresh ingredients!
