Marinating at work Above is a section of lean beef, a little more than 1.25" thick. It was marinated for 18 hours in a basic marinade of 3/4 cup canola oil and 1/2 cup distilled vinegar with 1 tablespoon salt and 10 drops of green food coloring. As you can see the dye colored the surface quite thoroughly and went below the surface through a crack in the upper left. The meat has been discolored only very slightly.

Some rules of thumb Marinate fish for 30 to 60 minutes at most, depending on the thickness. Chicken, turkey, and pork will begin taking on noticeable flavor in 2 to 3 hours, but 6 to 8 hours is optimal. Sirloin and chuck steaks need 6 to 24 hours and benefit from scoring the surface. The most tender steaks, like filets and ribeyes, need only an hour or two. Lamb tenderloins need only 15-30 minutes. The more acidic the marinade, the less time needed. Zipper or resealable bags are great for marinating and they need less liquid than bowls or tupperware. When you are done, you can throw them away. No cleanup. If you use pots, use stainless steel, glass, or ceramic. Never marinate in aluminum, cast iron, or copper. They react with the acids and salts. Turn the meat every few hours. Smaller pieces marinate faster, so consider cutting some meats into serving sizes. Always marinate in the refrigerator and cover the meat so it doesn't drip on other food. Never reuse marinades.

The Zen And Myths Of Marinades

Let's debunk some myths about marinades.

Marinades are thin liquids that foods swim in before cooking and they are bathed in myth and mystery. Unless they are heavy with salt, in which case they more properly are called brines, marinades do not penetrate meats like steak or lamb very far, perhaps no more than 1/8", even after many hours of soaking. Other meats, like chicken, turkey, and pork loin absorb a bit more marinade, while fish drink them up. Some other foods, especially eggplant and mushrooms absorb marinades rapidly. But many veggies are impermeable.

Nor do marinades tenderize red meat very much, especially since they do not penetrate very far and therefore cannot denature the protein bonds beyond the surface. That said, if they have some ingredients, they can make the surface mushy.

Marinades have another problem. They keep the surface wet and can impede browning, and browned meat has more flavor. They can also impede crisping of the surface.

If they contain sugar, they can burn and ruin the food if cooked hot and fast, like steaks and chops. Sugar is less of a problem for low slow roasting.

What marinades do best is find their way into cracks and crevices on the surface of meats making a flavorful baked on sauce. In general, it is best to think of marinades as a sauce.

The best marinades usually contain four working components: Salt, oil, flavoring, and acid, and if you remember the acronym SOFA, you can create your own easily.

As background for this article, read these articles, The Zen of Herbs & Spices, The Zen of Chiles, The Zen of Garlic, The Zen of Salt, and the Zen of Brines.

Refrigerate. Keep marinating meats in the fridge.

No sugar. While you're concocting your signature marinade, skip the sugar. The big fat sugar molecules just thicken the liquid and clog up the pores in the meat. Keep your marinade thin. And sugar can burn if you cook hot.

No alcohol. A lot of folks like to use wine, beer, and spirits in their marinades, but this may not be a good idea. Here's what the great Chef Thomas Keller says in his award winning The French Laundry Cookbook: "If your marinating anything with alcohol, cook the alcohol off first. Alcohol doesn't tenderize; cooking tenderizes. Alcohol in a marinade in effect cooks the exterior of the meat, preventing the meat from fully absorbing the flavors in the marinade. Raw alcohol itself doesn't do anything good to meat. So put your wine or spirit in a pan, add your aromatics, cook off the alcohol, let it cool, and then pour it over your meat. This way you have the richness of the fruit of the wine or Cognac or whatever you're using, but you don't have the chemical reaction of 'burning' the meat with alcohol or it's harsh raw flavor."

Use a nonreactive container. The acids in a marinate can react with aluminum, copper, and cast iron, and give the food an off flavor. So do your soaking in plastic, stainless steel, porcelain, or best of all, zipper bags. Pour the marinade and meat in the bag and squeeze out all the air possible and the meat will be in contact on most surfaces. Put it in the fridge and flip it over frequently.

Now here's a neat trick. Fresh pineapple, papaya, and ginger have enzymes that tenderize meat. Papain, the enzyme in papaya, is an enzyme in papaya and the main tenderizing ingredient in Adolph’s Meat Tenderizer. These enzymes work fast. Within 30 to 60 minutes the meat is ready for the grill. Surprisingly, pineapple and papaya add little flavor to the meat in such a short time. Some people like the softer meat, others feel it is mushy. You decide. The enzymes are destroyed by the canning and bottling process, so be sure to use fresh pineapple, papaya, and ginger if you want the tenderizing.

Cut to the chase. Cut the surface of the meat with a knife about 1/8" deep every 3/4" or so or poke holes in it with a fork. The liquid will get into the cracks and that will help flavor it as well as help a bit with penetration.

Go nekkid first. Chicken and turkey skin are almost all fat and they are an impenetrable barrier to marinades. If soaked, they only get soggy and won't crisp properly. So if the skin won't get crispy, what's the point? Get rid of it. Just empty calories. Skinless chicken will drink up more flavor. And it's healthier. And yes, you can get it crisp.

Save money. Some recipes call for marinating in barbecue sauce. Don't do it. It's just a waste of expensive sauce because it is too thick to penetrate very far.

Warning. Remember, all uncooked meat has microbes and spores. Used marinades are contaminated with raw meat juices so if you plan to use it as a sauce, it must be boiled for a few minutes.

A shortcut. If you don't want to make a marinade from scratch, just buy a bottle of your favorite oil and vinegar salad dressing. Salad dressings usually have all the necessary ingredients. Just make sure you don't get the Caesar. It has cheese and anchovies in it. We don't need no cheese or no stinkin' dead fish in our pork or steak.
