Pickled onions are simply thinly sliced onions submerged in an acidic solution, but they offer a surprising depth of flavor and versatility that elevates countless dishes. Here are three compelling reasons why you should always have a jar of these vibrant pink delights in your refrigerator.
First, pickled onions make food irresistibly mouthwatering. As explored in Salt Fat Acid Heat, acidity is a key component in stimulating our salivary glands. This response is so powerful that even the mere sight of sour foods can trigger it. While pickled onions aren’t as intensely sour as, say, a Warhead candy, their acidity is enough to add a delightful tang and enhance the flavors of any dish they grace.
Second, pickled onions provide crucial contrast in taste, texture, and appearance. Contrast is a fundamental element of a satisfying culinary experience. Imagine a peanut butter and jelly sandwich without the tartness of the jelly, cheese and crackers without the crunch, or a salad composed entirely of green vegetables. Pickled onions bring a bright, acidic taste, a satisfying crunch, and a vibrant pink hue to the table, enriching the sensory experience of your meals. They can even revitalize a simple peanut butter sandwich, adding a much-needed dimension of flavor.
Pickled onions offer limitless possibilities. The basic recipe involves thinly slicing red onions (root to stem for optimal texture and reduced pungency), boiling a mixture of equal parts water and vinegar with a pinch of salt, and pouring it over the onions. After cooling and refrigerating for a few hours, the onions transform into a vibrant pink. This basic recipe is just the starting point. Experiment with roasted spices like cumin and mustard seeds, add sliced serranos for a spicy kick, or explore other flavor combinations. These versatile additions can enhance everything from grilled chicken sandwiches to braised venison shoulder.
The applications are truly endless, so keep a jar of pickled onions in your fridge for whenever culinary inspiration strikes. From classic pairings to unexpected combinations, pickled onions offer a simple yet effective way to elevate your cooking.
