Peanut sauce is culinary magic, a blending of ordinary elements that becomes not just another condiment, but a unique sauce that can turn even the most tasteless bite into a delicious mouthful. It’s salty, sweet, acidic and bold — a sauce like no other.

For the uninitiated, Asian peanut sauce is a puree of peanuts, soy sauce, ginger, sesame, spices and often garlic, lemongrass and lime. It’s an essential in Thai cuisine, used on noodles, in salads, as a dip for spring rolls or dumplings, and as a marinade or glaze for meats and poultry. It’s also popular in other parts of Asia, including China and Southeast Asia, where it’s served with chicken or meat satay.

Making your own peanut sauce is a simple scoop, grate and stir task. But having bottled sauce on hand can be a big time-saver.

Great peanut sauce has bold peanut flavor that’s underscored — but not overpowered by — notes of ginger, lime, soy sauce and garlic. It’s sweet, salty and flavor-dense. Sadly, terrible options abound. Some are utterly bland, with only a hint of peanut flavor; others are so salty, your tongue will recoil.

Finding a good peanut sauce isn’t always easy. Some of the sauce attributes are apparent — shake the bottle to find out if the sauce is thick or thin. Note the color to get an idea of salt content — darker sauces typically have more soy sauce and are therefore saltier. But it’s tough to guess what’s in these sauces when the labels use generic terms such as “spices.”
