A creamy, tangy, slightly spicy classic sauce that comes together in seconds — this four-ingredient staple transforms simple shrimp cocktail, fried seafood, or crispy fries into an elevated appetizer with bright acidity and a subtle warming finish.
| Amount | Ingredient |
|---|---|
| 150 g (⅔ cup) | mayonnaise |
| 1 tbsp | ketchup |
| ½ tsp | lemon juice (freshly squeezed) |
| ½ tsp | cognac (optional) |
| To taste | cayenne pepper |
| To taste | kosher salt |
Cocktail sauce is one of those condiments that is so easy to make from scratch, you'll wonder why you ever bought it in a squeeze bottle. The base is simple: rich, emulsified mayonnaise balanced with the sweet-tangy depth of ketchup, brightened with fresh lemon juice, and given a whisper of heat from cayenne pepper. An optional dash of cognac adds a warm, aromatic complexity that elevates the sauce from everyday to elegant. The beauty of this recipe is its flexibility — adjust the ketchup for sweetness, the lemon for acidity, the cayenne for heat, and make it exactly as you like it. It takes less than five minutes to prepare and keeps beautifully in the refrigerator for a week.
Ingredient notes: Use a good-quality, full-fat mayonnaise — homemade (see Classic Mayonnaise, Volume 2) is ideal. The ketchup should be a standard variety, not spicy or flavored; it provides the sweet-tangy backbone. Freshly squeezed lemon juice is noticeably brighter than bottled. The cognac is optional but adds a subtle warm, oaky complexity; if omitted, increase the lemon juice by ¼ teaspoon. Cayenne pepper provides a gentle heat that builds gradually — start with a pinch and adjust upward.
| Mistake | Why It Hurts | The Fix |
|---|---|---|
| Using low-fat or whipped mayonnaise | The sauce will be thin, watery, and lack the rich, creamy texture needed to cling to seafood | Use full-fat, regular mayonnaise — homemade is best |
| Adding too much cayenne at once | An unexpectedly fiery sauce that overwhelms the delicate flavor of shrimp or seafood | Add cayenne in small pinches, tasting as you go |
| Using bottled lemon juice | Flat, one-dimensional acidity that lacks the bright, clean finish of fresh lemon | Squeeze fresh lemon juice — the difference is noticeable |
| Skipping the rest time | The flavors taste separate and harsh rather than blended and harmonious | Refrigerate for at least 30 minutes before serving |
| Over-whisking | The sauce won't break, but over-whisking can incorporate too much air, making it appear thin and frothy | Whisk just until smooth and uniformly colored — about 30 seconds of vigorous whisking |
| Storage Method | Details |
|---|---|
| Refrigerator | Store in an airtight jar or container for up to 1 week. The sauce will thicken slightly as it chills. Stir before each use. |
| Freezer | Not recommended — the mayonnaise-based emulsion breaks upon thawing, resulting in a watery, separated sauce. |
| Room temperature | If serving at a party, do not leave at room temperature for more than 2 hours. Return unused portions to the refrigerator promptly. |

Can I use Greek yogurt or sour cream instead of mayonnaise?
Not as a direct substitute — the sauce will be thinner, tangier, and less rich. If you prefer a lighter sauce, use half mayonnaise and half full-fat Greek yogurt, and reduce the lemon juice slightly. The texture will be looser but still flavorful.
What if I don't have cayenne pepper?
Paprika (sweet or smoked) is the best substitute — it adds color and warmth without significant heat. For actual spiciness, use a tiny pinch of chili powder, red pepper flakes (crushed to a powder in a mortar), or a few drops of hot sauce.
Can I make this without the cognac?
Absolutely — the sauce will still be delicious. The cognac adds warmth and complexity but is entirely optional. If omitting it, consider adding a tiny pinch of black pepper or a drop of Worcestershire sauce for additional depth.
Is this the same as seafood cocktail sauce from the store?
Not exactly. Traditional bottled cocktail sauce in the UK and US is typically ketchup-based with horseradish and Worcestershire sauce. This version is mayonnaise-based, making it creamier and closer to what many Italian and French restaurants serve alongside shrimp cocktail or fritto misto.
Can I use this as a salad dressing?
It is quite thick for a salad dressing, but you can thin it with a tablespoon of milk, buttermilk, or water to reach a drizzle-able consistency. It works wonderfully as a dressing for a shrimp or crab salad.
How do I know if my cocktail sauce has gone bad?
Homemade cocktail sauce will keep for about 1 week in the refrigerator. Signs of spoilage include: an off, sour smell; visible separation that doesn't re-emulsify when stirred; or any sign of mold. When in doubt, throw it out.
