With soaring grocery prices, I’ve been passing up the expensive, well-marbled T-bone steaks for more affordable proteins. Top-notch ingredients will taste great as long as you don’t screw them up, but humbler ingredients often need a little help to taste delicious. Marinades can boost flavor and tenderness, helping you create delicious meals even with budget-friendly cuts. Understanding how they work and their limitations will make you feel more confident in your cooking choices.
Marinades are acidic liquids, such as vinegar, wine, citrus juice, buttermilk or yogurt, which are used to enhance moisture, tenderness and taste. Acid-based marinades work by denaturing proteins on the meat’s surface. Writing for Serious Eats, Kenji López-Alt explained that acidity uncoils tightly bound outer protein chains, relaxing muscle fibers enough to allow minor liquid absorption. However, penetration remains extremely shallow. Food scientist Harold McGee cites research showing that acidic solutions seep only 1 to 2 millimeters into meat over a full 24-hour period. The shallow penetration of standard acidic marinades often leaves interiors under-marinated and exteriors over-marinated. Leaving meat in strong acidic mixtures longer than four to six hours can make the surface soft and mushy.
Yogurt-based marinades are a gentler alternative to citrus, wine or vinegar marinades. Because yogurt contains lactic acid – far milder than acetic or citric acid – it tenderizes meat more gradually. The lactic acid, calcium, and natural enzymes in yogurt unwind protein structures and break down collagen, resulting in succulent meat that browns beautifully.
Yogurt’s viscosity holds ground spices, aromatics and oils directly against the meat’s surface, creating a protective coating that seals in moisture during cooking, especially when grilling over an open flame. The lactic acid in yogurt is suspended in a dense fat-and-protein gel network, which slows acid penetration and makes it almost foolproof for long, overnight marinades. This coating not only tenderizes but also helps the meat caramelize and char beautifully over direct flame – crucial for dishes like tandoori chicken and grilled kebabs – and keeps the meat moist and flavorful.
Spiced yogurt skewered lamb kebabs
Lamb can be a bit gamey, but a warm-spiced yogurt marinade tames its intensity and tenderizes muscle fibers.
Serves 4
Ingredients:
1½ pounds lamb shoulder or leg of lamb, cut into 1-inch cubes
1 cup plain full-fat yogurt
1 tablespoon ground cumin
1 tablespoon ground coriander
1 teaspoon ground turmeric
½ teaspoon cayenne pepper
1-inch fresh ginger, finely grated
4 cloves garlic, minced
1½ teaspoons kosher salt
Skewers (soaked in water if wooden)
Preparation:
In a mixing bowl, combine the yogurt, cumin, coriander, turmeric, cayenne, ginger, garlic and salt. Stir vigorously to distribute the spices evenly.
Add the cubed lamb to the mixture, turning to coat all sides. Transfer to a resealable gallon plastic bag and refrigerate overnight.
Thread the marinated lamb cubes onto your prepared skewers, leaving a tiny bit of space between each piece so heat can circulate evenly.
Heat an outdoor grill to high heat and lightly oil the grates. Grill the skewers for eight to 10 minutes, turning every couple of minutes, until deeply charred on the outside and medium-rare to medium inside. Alternatively, set your oven broiler to HIGH and place the skewers on a wire rack set over a baking sheet. Broil four inches from the heating element for eight to 10 minutes, turning once halfway through.
Serve over basmati rice and garnish with mint leaves and/or cilantro.
After retiring from a 40-year career in dentistry at age 66, Dr. Peter Glatz embraced his lifelong dream of becoming a professional chef. For the next seven years he gained hands-on experience in highly regarded kitchens nationwide. His transition from the exacting world of dentistry to the inventive world of culinary arts is a testament to the possibility of reinvention by teaching cooking classes at Prairie Fruits Farms and Creamery in Champaign.
