  If your cookie dough is too dry, stir in a tablespoon or two of milk.
If cookies harden and stick to the cookie sheet or a cake sticks in the pan, return them to the oven for 1 minute.
To cool cookies, place them on a wire rack or a sheet of wax paper sprinkled with sugar.  Cookies will cool without getting soggy.
Make side dishes ahead, and freeze them.
Keep berries, chopped green bell pepper, chopped onion, parsley, soft breadcrumbs, shredded cheese, and a variety of toasted nuts on hand in zip-top plastic freezer bags in your freezer.
When frying or sautéing, keep grease splatters as contained as possible by placing a metal colander on top of the skillet.
Make use of your microwave for thawing foods or jump-starting the cooking process for meats.
Soups and stews can be made less salty or fiery by adding several large pieces of raw potato. Don't forget to remove the potato before serving your dish!
Failed pralines can be crumbled over ice cream for a sweet dessert.
When a cake turns out dry or layers fail to come out of pans evenly, make parfaits or a trifle. Simply crumble the cake into glasses or a dish, and layer with whipped cream and fresh fruit.
For a quick chill on wine and champagne, fill the sink with cold water and ice, and submerge the bottles. This will cool the liquid faster than the freezer or ice bucket.
When the chocolate you are melting seizes (clumps), stir in a tablespoon of vegetable oil or shortening to smooth things out.
To thicken a mousse, stir in whipped heavy cream.
If you accidentally scorch a recipe or sauce, do not scrape the bottom of the pan. Transfer the remainder of the sauce to a clean pan immediately.
If a cake gets too brown on top, simply cover it with whipped topping or a sauce.
If your chocolate pie is soggy, serve chocolate pudding. If your savory cheesecake doesn't set, have dip with crackers.
Dry stuffing or dressing can be remedied with a little chicken broth.
Strain lumps from your gravy, and mix 1 tablespoon cornstarch and 2 tablespoons cold water; add this mixture slowly to thicken the gravy.
