Marinating as Flavoring Agent (vs. Tenderizing)
Marinades are used for tenderizing as well as for adding flavor to meats.
The acid in marinades like vinegar or citrus juice work by breaking down connective
tissues. Since the reaction between the meat or veggies and the marinade is
a chemical process, there are a few factors that can affect a recipe. Time
is a key factor, of course, but temperature is crucial. The colder the marinating
food is kept the slower the reaction will be. The longer a food marinates the
more tender it will be but too much time may impart more flavor than you want.
The amount of marinade is important as well. As mentioned elsewhere zipper
bags are indispensable in the kitchen and this is a perfect example because
you can use less marinade and still get maximum coverage. Plus you can "turn" the
meat in the bag easily to coat it completely.
