Cocktail Sauce
Koktejlová omáčka is the Czech name for a creamy, salmon-pink cold sauce made by combining mayonnaise or a mayonnaise-style emulsion with ketchup or tomato paste. It is close to the British Marie Rose sauce and is not the American horseradish-and-ketchup cocktail sauce.
In practice
How to store
- On the counter
Unopened jars and bottles of shelf-stable commercial sauce can be stored at room temperature, away from heat and sunlight, until the best-before date. Products sold from the chilled cabinet, or labelled to be kept refrigerated, must stay in the fridge even before opening. Do not leave an opened sauce or a homemade sauce standing at room temperature. When serving at a buffet or barbecue, keep it cool and put it back in the fridge promptly.
- In the fridge
After opening, keep it refrigerated at 2–6 °C and use it within the period stated on the label. Always use a clean spoon. Store homemade cocktail sauce in a closed container in the fridge and eat it within 1–2 days, especially if the mayonnaise was made with raw egg yolk.
- In the freezer
Not suitable for freezing. The emulsion separates on thawing and becomes oily and grainy.
How to choose
Read the label. Czech products differ a lot in fat content (stated as a percentage on the pack), in the oil used (rapeseed or soybean) and in whether they contain whole egg, egg yolk or neither. For a richer sauce closer to homemade, choose one with a higher fat content and egg listed near the top of the ingredients. For a lighter dip, choose one with a lower fat content. Check the allergen information if anyone eating it has an allergy. Egg and mustard are common, and some versions also contain milk powder, soy or other allergens shown in bold. Large catering tubs (around 3 l) are good value for parties but only make sense if they will be used up quickly once opened.
What to swap in
Best swap
Mix good mayonnaise with ketchup and season with lemon juice and a little horseradish. This is the classic homemade version and tastes much like the shop-bought sauce.
In a pinch
Thousand Island-style dressing or a burger sauce made from mayonnaise and tomato. Both are similar in colour and creaminess, though usually sweeter or with added pickles.
Preparation
The shop-bought sauce is ready to use: stir it and serve it cold. For a quick homemade version, mix mayonnaise and ketchup, typically in roughly equal amounts (adjust to taste), then season with lemon juice, salt and pepper. Optional additions are a little grated horseradish, a few drops of brandy or cognac, Worcestershire sauce or a pinch of hot paprika. Some cooks replace part of the mayonnaise with plain yoghurt for a lighter sauce. If you make the mayonnaise yourself from raw egg yolks, use very fresh eggs, keep everything chilled and eat it the same day or the next. People in vulnerable groups should use a commercial or pasteurised-egg base.
Don't toss it
Use up the last spoonfuls in a jar or bottle by stirring them into a potato or pasta salad, or by spreading them thinly on a sandwich or burger bun. Leftover homemade sauce is best used the next day as a sandwich spread rather than kept longer.
In the kitchen
Cooking
Koktejlová omáčka is a cold sauce and is not cooked. It is served chilled as the dressing for prawn cocktail (krevetový koktejl) and chicken cocktail, as a dip for breaded prawns, fried fish and fries, as a spread for burgers and sandwiches, and alongside grilled meat. Add it to hot food only at the table. Heating it causes the emulsion to split.

What it is
Koktejlová omáčka is the Czech name for a creamy, salmon-pink cold sauce made by combining mayonnaise or a mayonnaise-style emulsion with ketchup or tomato paste. It is close to the British Marie Rose sauce and is not the American horseradish-and-ketchup cocktail sauce. Czech shops sell it ready-made as an emulsified sauce in glass jars, plastic squeeze bottles and large catering tubs. Hellmann's makes one, and supermarkets such as Billa sell their own versions. Many Czech households also make it at home by stirring ketchup into mayonnaise and seasoning it with lemon juice and a little horseradish or brandy. On Czech labels the shop-bought product is usually described as a cold emulsified sauce (studená emulgovaná omáčka), and the fat content is stated on the pack. Most products are much lighter than full mayonnaise. One supermarket version is labelled at 30 % fat, while mayonnaise in Czech shops typically contains about 76–80 % fat.
How it tastes
Smooth, rich and creamy, with a gentle sweetness from the ketchup or tomato paste and sugar, balanced by acidity from vinegar and lemon. Many versions have a light warmth from paprika, mustard or horseradish, but it is never as sharp as American cocktail sauce. The colour ranges from pale pink to orange-pink, depending on how much tomato is in it.

Varieties
Shop-bought emulsified sauce
The most common form in Czech shops. Most are shelf-stable until opened and are sold in jars and squeeze bottles for home use and in tubs of around 3 l for catering. Recipes differ by producer. Some are based on vegetable oil with egg and egg yolk, tomato paste, vinegar and sugar. Others are lower-fat emulsions thickened with starch and xanthan gum and seasoned with paprika, mustard seed, horseradish and garlic.
Homemade
Mayonnaise mixed with ketchup and seasoned with lemon juice, plus horseradish and often a dash of brandy or cognac. Lighter versions replace some of the mayonnaise with yoghurt, and spicier ones add chilli or Worcestershire sauce.
Imported German-style products
Shops selling German groceries in Czechia also offer cocktail sauces of the same creamy pink type.
Relatives (different products)
British Marie Rose sauce is the nearest relative and is essentially the same mayonnaise-and-tomato idea. American cocktail sauce is a different condiment: a sharp, red mix of ketchup or chilli sauce with horseradish and no mayonnaise. Czech shoppers should not expect that when buying koktejlová omáčka.
History
The name comes from the seafood cocktail, the prawn cocktail served in a glass, which this sauce traditionally dresses. In Central Europe the creamy mayonnaise-and-tomato version became the standard meaning of 'cocktail sauce', in line with the British Marie Rose style rather than the American one. Today it is a common ready-made condiment in Czech supermarkets, sold alongside mayonnaise and tartar sauce (tatarská omáčka).
Science
Koktejlová omáčka is an oil-in-water emulsion: tiny droplets of vegetable oil spread through a watery phase of vinegar, water and tomato. In mayonnaise-based versions, the lecithin and proteins in egg yolk act as the emulsifier and stop the oil from separating. Lower-fat commercial sauces contain less oil, so they use modified starch and stabilisers such as xanthan gum (E415) to keep a thick, spoonable texture.
Vinegar, lemon juice and citric acid (E330) make the sauce acidic, which helps preserve it and gives it its tang. Commercial sauces are made with pasteurised egg, and some contain preservatives such as potassium sorbate. The pink colour comes from tomato paste or ketchup, and in some products from paprika extract.
Sourcing and ethics
The main ingredients to consider are the oil and the eggs. Czech products use rapeseed or soybean oil, and the oil's source is not always stated. Some brands state the egg-farming method on the label (for example, eggs from free-range hens). If this matters to you, check the ingredient list. Making the sauce at home from mayonnaise made with eggs of a known origin gives the most control. Large catering tubs reduce packaging per portion, but only if the contents are used up before they spoil.
