Using buttermilk to flavor pork
The problem with buttermilk is there isn’t a lot of "real" buttermilk around.
The good news is that the newfangled buttermilk available at most grocers isn’t all that bad. Better yet, it’s easy to make the real stuff yourself.
But first, a buttermilk primer. As its name suggests, buttermilk is the tangy milk-like liquid left behind when cultured cream is churned to make butter. At least that’s how they made it in the old days. Today, it’s usually commercially produced by adding cultures (think the bacteria that produces yogurt) to low- or no-fat milk.
Either way, you end up with an acidic, thick, milky liquid.
Let’s start with buttermilk’s signature tang. It’s tangy because it’s acidic, and acidic ingredients make for great marinades. Give chicken, pork or turkey a buttermilk bath and you’ll get especially tender, flavorful meat. Before you add the meat, just whisk in whatever seasonings you want.
And that same tang turns out killer mashed potatoes. Use it in place of regular milk, then mash away. Ditto for sweet potatoes.
Next time you’re making vinaigrette for your salad or roasted vegetables, add buttermilk for rich, luxurious flavor. Try a blend of olive oil, buttermilk, lemon juice, strawberry jam, salt and black pepper.
Buttermilk also is delicious in fruit smoothies. Substitute buttermilk for a quarter to half of the liquid you’d normally use.
When shopping for buttermilk, most of what you find at the grocer is labeled "cultured buttermilk," which generally refers to low-fat or skim milk that has been cultured. But a number of regional dairies now sell "real" buttermilk, a smart use of the liquid left over from their butter making operations.
But it’s also easy enough to make your own. And the best part is that in the process, you also get some delicious homemade butter (the very best there is). Just purchase a pint of the very best quality heavy cream you can find. Place it in a food processor and process for several minutes.
The cream will get thick and resemble whipped cream. Continue processing until the whipped cream breaks and the fat solids come together as butter. At this point there should be one or two large clumps of butter and a fair amount of milky liquid in the processor. Pour off the liquid -- this is your buttermilk. Season the butter with salt, then use or refrigerate. It’s that simple.
Start to finish: 20 minutes, plus marinating
1-pound pork tenderloin
1 cup buttermilk
1 tablespoon plus 1 teaspoon Thai red curry paste, divided
1 teaspoon kosher salt
2 cups panko breadcrumbs
1/2 teaspoon ground black pepper
1/4 cup mayonnaise
1/2 teaspoon cider vinegar
4 burger rolls
Boston or other leafy lettuce
1 large tomato, sliced
Cut the tenderloin crosswise into thin rounds, each about 1/4 inch thick. One at a time, set each round between sheets of plastic wrap and pound evenly thin using a meat mallet or rolling pin.
In medium bowl, whisk together the buttermilk, 1 tablespoon of the red curry paste and salt. Add the pork and ensure it is evenly covered by the liquid. Refrigerate for at least 1 hour and up to 8 hours.
When ready to cook, heat the oven to 400. Coat a baking sheet with cooking spray.
In a wide, shallow bowl, mix the breadcrumbs and pepper. Remove the pork cutlets from the marinade. Dredge each piece through the breadcrumbs, patting them on as needed to coat evenly. Arrange the pork cutlets on the prepared baking sheet.
Bake for 10 minutes, or until lightly browned and cooked through.
Meanwhile, in a small bowl, whisk together the remaining 1 teaspoon of red curry paste, the mayonnaise and vinegar. Slather a quarter of the mixture over the bottom half of each burger roll. Top with lettuce and tomato, then 1 or 2 pork cutlets.
