This is the Thai peanut sauce recipe I grew up with, built in a pan, not blended in a machine. The coconut milk blooms the curry paste first. The ground peanuts go in after. It thickens the way a real sauce should, from the inside out. It takes fifteen minutes. It will last in the refrigerator for five days, getting better each one.
1/2cupground roasted peanuts or natural unsweetened peanut butter
2tablespoonsred curry paste
2tablespoonsbrown sugar
2tablespoonsfish sauce
1teaspoonsoy sauce
1/2teaspoonground cumin
1/4cupwateradjust as needed for desired consistency
2tablespoonslime juicefreshly squeezed
1/4cupcrushed peanutsfor garnish
Chopped cilantrofor garnish
Instructions
Combine the Base Ingredients: Open the can of coconut milk without shaking it. Spoon the thick cream from the top into your saucepan. Medium heat. Let it warm until it begins to bubble at the edges, about two minutes. Add the red curry paste. Stir. Watch it turn the cream orange, then deep red. The smell changes immediately. That is the fat releasing the aromatics. That is the moment the sauce begins.Once the paste is blooming and fragrant, add the remaining coconut milk, natural peanut butter, brown sugar, fish sauce, soy sauce, and ground cumin. Whisk together until smooth and fully combined. The color will lighten slightly as the milk joins the paste. Place over medium heat and bring to a gentle simmer, stirring frequently to prevent sticking.
Simmer to Develop Flavors: As the sauce warms and the ingredients meld together, assess the consistency. The sauce will thicken as it simmers. If it seems too thick, gradually add up to a quarter cup of water, stirring well after each addition until you achieve the right silky texture. Stir continuously and keep the heat at a gentle simmer, not a boil. Boiling breaks coconut milk. A simmer holds it together. Simmer for five to ten minutes until the flavors have harmonized.
Perfect the Consistency: Remove from heat. Stir in the fresh lime juice immediately. Taste and adjust: more lime for sour, more palm sugar for sweet, more fish sauce for salt. The sauce should be savory, sweet, and sour all at once, no single flavor louder than the others. The lime goes in off the heat so the brightness stays present rather than cooking off.
Serve:Let the sauce sit for five minutes off the heat before serving. It continues to thicken as it cools. Serve warm, not hot. It should pour slowly from the spoon. If it has gone too thick, add a tablespoon of warm water and stir. Transfer to a serving bowl, sprinkle crushed peanuts and serve alongside satay or anything else worth dipping.

Notes
The sauce thickens significantly as it cools. If you are making it ahead, pull it from the heat when it still looks slightly thin. By the time it reaches the table, it will be exactly right. If it tightens too much in the refrigerator, warm it gently with a splash of water and stir until it comes back together.Red curry paste varies by brand. Maesri runs hotter than most. If you are using a new brand for the first time, start with one and a half tablespoons and taste before adding more. The paste is the heat and the aroma both. You cannot take it back.This sauce does not belong only to satay. Spoon it over roasted vegetables. Use it as a dipping sauce for spring rolls. Thin it with lime juice and toss it with rice noodles. My mother would have done all of these things. She wasted nothing.This sauce does not belong only to satay. Spoon it over roasted vegetables. Use it as a dipping sauce for spring rolls.
