The Lime Juice Marinating Mistake That's Ruining Your Steaks

If you're planning to marinate a cut of steak, lime juice will give your steak marinade a flavor boost. A few squeezes of a fresh lime bring a tangy and zesty complement to steak's umami-rich savoriness. As a highly acidic ingredient, lime juice is also responsible for denaturing the proteins in steak. The proteins in raw meat are wound into tight knots, which the acid in lime juice loosens to make the meat melt-in-your-mouth tender. However, while acidic fruit juice can be a key ingredient in a tenderizing steak marinade, leaving your steak too long in a lime juice marinade will effectively ruin the meat as those protein structures will break down too much.

If you over-marinate steak in lime juice, the protein structures won't just unravel, they'll disintigrate, leading to the destruction of the steak's muscle fibers and collagen structures, resulting in a mushy, mealy or even rubbery texture. In one way or another, over-marinating will ruin the consistency of your steak. So be conservative with marinating times. All you need is a 30 minute marinade for many different types of steak to absorb flavor and tenderize. Of course, depending on the cut of steak in question, marinade times can require 2 to 8 hours. But overnight or 24-hour lime juice marinades are a recipe for disaster.

Not all cuts of steak need to be marinated; the ideal candidates are leaner cuts that would be especially tough without marination. Eye round, round steaks, skirt, and flank steaks all benefit from a lime juice marinade, but do check out our full list of expert-recommended cuts here. Of course, lime juice isn't the sole ingredient in a tenderizing marinade. You'll need to balance the acidity with other liquid ingredients, not to mention a combination of spices, aromatics, and herbs for flavor.

You can even blend lime juice with another acidic ingredient like vinegar, but a general rule of thumb for acidic marinade ingredients is to apply the proportions of a vinaigrette to a marinade. Consequently, you should use three parts oil and seasonings to one part acid. Lime juice is a key ingredient in Mexican and Southeast Asian cuisines, so you may wish to draw inspiration from these distinct culinary cultures to create flavorful marinades. For example, marinate skirt steak in chili powder, tequila, lime juice and zest, oregano, garlic, and cilantro as we do in this tequila and lime grilled chicken recipe. Use this lime marinated skirt steak for your next meal of arrachera tacos or sizzling fajitas. You can give steak an even stronger burst of umami by adding soy sauce or Worcestershire sauce to your lime marinade.
