The Secret to the Best Peanut Sauce 

The key to a silky, well-balanced peanut sauce is mixing until smooth. Mixing the peanut butter with hot noodle water helps break it down, making the sauce smooth and creamy rather than thick and clumpy. If you keep peanut butter in the fridge like I do, you can microwave it for 15 to 20 seconds to soften it up before mixing with the hot noodle water. Adding soy sauce, vinegar, and sugar ensures a perfect balance of savory, tangy, and slightly sweet flavors.

Why These Spicy Peanut Noodles Are So Addictive 

This dish delivers the perfect balance of creamy, spicy, tangy, and umami flavors in every bite. The peanut butter adds richness, while chili oil brings heat and depth. A splash of Chinese black vinegar cuts through the richness, giving the sauce a subtle tang that can only be found in Sichuan food.

Chinese Black Vinegar vs. White Vinegar

Chinese black vinegar is made from fermented rice or wheat and is typically aged. The aging process gives the vinegar its dark color and deep, rich and slightly smoky flavor profile. As a result, you’ll often find this ingredient used in Asian recipes. White vinegar, on the other hand, has a more sharp and acidic taste profile. If you don’t have Chinese black vinegar, use white vinegar or rice wine vinegar.

Allergic to Peanuts? What to use instead 

If you have a peanut allergy, there are a few substitutes that could be used; the taste obviously won’t have the peanut flavor, but the dish should still have the creamy, tangy, and spicy flavor profile.  Sunflower seed butter has the same consistency as peanut butter but has a mild, slightly sweet flavor. You could consider reducing the amount of sugar slightly to accommodate this. Tahini (sesame seed paste) is also available at the grocery store and could also be used. You can experiment with different types of substitutes to create the dish you want. It’s your food, eat it how you like!
