A tangy, silky sour sauce that brightens grilled meats and roasted veggies with sharp vinegar notes, buttery richness, and a smooth texture—perfect for bold, comfort‑food lovers.
Ingredients
Instructions
- Combine chopped onion, vinegar, and water in a saucepan.
- Cook over medium heat for 10 minutes, letting the onions soften and the liquid reduce slightly.
- Whisk melted butter, egg yolks, flour, and salt together until smooth.
- Pour the hot liquid from the saucepan over the butter mixture while whisking continuously.
- Blend thoroughly until the sauce is thick and glossy.
- Simmer for 1 minute to ensure the mixture is smooth and fully cooked.
- Serve immediately or keep warm until ready to use.
Tips & Substitutions
To enhance the sour sauce, consider sautéing the chopped onion in the melted butter before adding vinegar and water for a deeper flavor. If you want a creamier texture, you can substitute half of the water with heavy cream. For a vegan version, replace egg yolks with a mixture of cornstarch and water, and use plant-based butter.
Serving Suggestions
This sour sauce pairs beautifully with grilled fish or roasted vegetables as a zesty accompaniment. It can also elevate dishes like Casey And Rebecca Brown'S Scalloped Potatoes or be drizzled over steamed asparagus. Serve it warm for the best flavor and texture.
Storage & Reheating
Store any leftover sour sauce in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it on the stove over low heat, whisking continuously to maintain its smooth texture. Avoid boiling as it may cause the sauce to separate.

Frequently Asked Questions
Can I use a different type of vinegar?
Yes, you can substitute the vinegar with apple cider vinegar or white wine vinegar for a different flavor profile. Each type of vinegar will impart its unique taste, so choose one that complements your main dish.
What can I do if my sauce is too thick?
If your sauce turns out too thick, gradually whisk in a little more water or broth until you reach your desired consistency. This will help loosen it without compromising the flavor.
Is this sauce suitable for meal prep?
Yes, you can prepare this sauce in advance and store it in the refrigerator. Just remember to reheat it gently before serving, as it thickens when cold. It’s a great addition to meal prep for a quick flavor boost.
