Mustard caper sauce is typically made with mustard and chopped capers, often mixed with oil and lemon juice or vinegar. Some versions add mayonnaise or yogurt for a creamier texture, so the exact ingredients vary by recipe.
Use mustard caper sauce as a finishing sauce for fish, spoon it over vegetables or potatoes, or spread a little inside a sandwich. Its salty, tangy flavor is strong, so start with a small amount and add more to taste.
Yes, mustard caper sauce pairs well with salmon, especially when the fish is baked, grilled, or pan-seared. The sharp mustard and briny capers cut through salmon’s richness; serve the sauce on the side or add a small spoonful on top.
Yes, mustard caper sauce works with roasted or grilled chicken. Its acidity adds contrast to simply seasoned meat, while a creamy version can also be used as a sandwich spread or served alongside sliced chicken.
You can make mustard caper sauce without mayonnaise by stirring chopped capers into mustard with olive oil and lemon juice or vinegar. For a creamy alternative, mix in plain yogurt; add it gradually until the sauce reaches the consistency you want.
To make mustard caper sauce less sharp, stir in a little olive oil, yogurt, or another creamy ingredient. If the capers make it too salty, use rinsed capers next time rather than adding extra salt or more mustard.
Rinse capers before adding them to mustard caper sauce if they taste very salty or are packed in brine. Drain them well and chop them; rinsing is less necessary when the sauce needs their full briny flavor.
Keep mustard caper sauce covered in the refrigerator and follow the storage instructions if it is a packaged product. For homemade sauce, use a clean utensil each time and make a small batch to use within a few days.
You can freeze mustard caper sauce, but its texture may separate or become grainy after thawing, especially if it contains mayonnaise or yogurt. Stir it well after thawing and use it in a cooked dish if the texture is no longer smooth.
Serve lemon-herb butter, a simple vinaigrette, or tartar sauce instead of mustard caper sauce with fish. Choose lemon and herbs for a fresher, lighter flavor, or tartar sauce if you want a creamy condiment with pickles.

Mustard caper sauce brings sharp, tangy mustard together with the salty, briny bite of capers. Recipes vary: some mix in oil, lemon juice or herbs, making it a flexible condiment rather than a single fixed regional recipe. The pairing is familiar in European and Mediterranean-style cooking, especially alongside fish.
Use it with grilled or roasted fish, spoon a little into a sandwich, or loosen it with lemon for a salad dressing. Its punchy, savoury flavour and the occasional firm pop of chopped capers can brighten simply cooked foods. It is relatively energy-dense, with 166 calories per 100 g, so a modest spoonful is often enough; for a lighter sauce, stretch it with lemon juice or plain yoghurt.
