Generalizing a marinade
In my mind, there are 4 main aspects of a marinade mixture: salt, acid, duration (of soaking the meat, tofu, etc.) and other flavoring ingredients.
- Salt: increases moisture/juiciness of the meat and adds flavor, obviously. In my recipes here, the salt concentration is generally between 3 and 8%, going up as high as 10% for Alton Brown's shrimp brine and also for the Mediterranean chicken marinade.
- Acid: increases perceived tenderness of the meat. In the recipes here, the concentration of acidic ingredient (citrus juice, vinegar, etc.) in the marinade is usually around 35% and goes as low as 20% for the teriyaki and somewhat higher for the marinated vegetables.
- Duration: obviously, the longer it soaks, the stronger the flavor and more tender/juicy the meat. On the flipside, if it sits too long, it it will become too salty or overly acidic or will start to break down and become mushy. In the recipes here, the duration is usually between 4 and 24 hours (and less than 1 hour for the seafood). In general, the thicker the piece of meat, and the more surface area there is, the longer the duration should be.
- Other flavorings/ingredients: some of the ingredients that kept reappearing in the recipes here include: chopped herbs, spices, garlic/ginger/shallots, chile/pepper, flavored oils, soy, mustard.
