You are standing at the dairy shelf and see double cream, cooking cream and light cooking cream side by side. All three are called cream, all three sit in the chiller, and yet a sauce turns out very differently with each. The difference lies mainly in one number: the fat percentage.
Cream is surrounded by half-truths. This article lines up the differences, explains why cream splits and takes the best-known misunderstandings apart one by one.
The three at a glance
| Type | Fat (approx.) | Can be whipped | Cooking in sauces | Suits |
|---|---|---|---|---|
| Double cream | at least 35% | yes | yes, also reducing | cakes, mousse, ganache, rich sauces |
| Cooking cream | 15 to 20% | no | yes, hardly splits | sauces, soups, pasta, quiche |
| Light cooking cream | 5 to 10% | no | yes, but thinner | light sauces and soups |
Percentages differ by brand. Always check the pack for the fat percentage of the product you buy.
What is the difference?
Double cream
Double cream contains at least 35% milk fat. That fat is what makes it whippable: while whipping, air bubbles are trapped in a network of fat globules. It is rich in flavour and stands up well to heat, but it is also the heaviest of the three.
Cooking cream
Cooking cream has less fat, usually between 15 and 20%. That makes it lighter, but it can no longer be whipped. Many cooking creams also contain a thickener, such as starch, that binds the cream and helps prevent splitting. That is exactly what you want for a sauce: creamy, stable and predictable.
Light cooking cream
Light cooking cream has even less fat, roughly 5 to 10%. It gives a creamy feel with fewer calories, but the sauce becomes thinner and less full in flavour, because fat carries flavour. To make up for the missing fat there is often more thickener in it. It is a fine choice for light sauces and soups, but not a full replacement for double cream.
What does the label say?
- Cream in the ingredients list means it is dairy.
- Thickener (such as starch or carrageenan) is often found in cooking cream and light cooking cream, and not in double cream.
- Plant-based versions made from soy, oat or coconut are not called cream, but for example cuisine or cooking creme. They behave differently from real cream.
Why does cream split?
Splitting means that cream falls apart: you see flecks or a greasy layer. This comes from a combination of three things.
- Little fat: the proteins clump together faster because there is less fat between them.
- Acid: wine, lemon juice, tomato and vinegar make milk protein curdle.
- Boiling hard: a rolling boil breaks cream down faster.
More fat and a thickener make cream more resilient. To be sure, add the acid only at the end, off the heat, and let the sauce simmer gently instead of boiling hard. Or bind the sauce with a light roux.
Truths and untruths
Cooking cream is just double cream you cannot whip
Untrue. Cooking cream has a lower fat content and often a thickener. It is a product of its own for the pan, not double cream under another name.
You cannot whip cooking cream
True. There is too little fat to hold the air bubbles. For whipping you need double cream.
You must not boil double cream
Untrue. Double cream works fine in a hot sauce and can even be reduced to a thick, glossy sauce. Only boiling very hard for a very long time can make even double cream separate. What is true: whipping for too long turns double cream into butter.
Light cooking cream is the same as cooking cream, just with fewer calories
Untrue. The sauce becomes thinner and less full, and the composition is different. You notice the difference in flavour and in the structure of the sauce.
Light is healthier
Partly true. Per serving there is less fat and therefore less energy. But if you then thicken the sauce with extra flour or cheese, part of that advantage is lost again. What is best depends on the whole meal.
You can always swap them one to one
Partly true. In soups and sauces it works, although the sauce gets thinner the less fat there is. For whipping, mousse, panna cotta and ganache you need double cream, because the fat provides the structure.
Cream always splits when you add wine or lemon
Untrue. It depends on the fat content, the heat and the moment. Double cream and cooking cream with thickener can handle a splash of wine if you heat gently. Light cooking cream splits sooner, so add the acid right at the end.
Crème fraîche is the same as cooking cream
Untrue. Crème fraîche is soured, has its own fresh taste and a firmer structure. It handles heat well, but does not suit every sauce.
The longer you reduce, the thicker the sauce
Partly true. With double cream and cooking cream, reducing works through evaporation. With light cooking cream it achieves little and the sauce splits sooner. Use a roux or a little cornflour instead.
Which cream for which dish?
| Dish | Best choice | Why |
|---|---|---|
| Cream on cake or pie | double cream | only cream with plenty of fat can be whipped |
| Ganache, chocolate mousse | double cream | the fat provides firmness |
| Pasta sauce, cream sauce with meat | cooking cream | creamy and stable, hardly splits |
| Finishing a soup | cooking cream or light cooking cream | depends on how rich you want it |
| Sauce with wine, lemon or tomato | cooking cream, or a sauce on a roux | acid makes cream split sooner |
| Quiche or oven dish | cooking cream | holds its shape when baked |
| Light sauce | light cooking cream with roux or cornflour | the extra binding makes up for the missing fat |
In the recipe Chips with truffle cream sauce and Parmesan you can see this in practice: a light roux with cooking cream gives a sauce that is just thick enough and does not split.
Thickening a light cream
- With a roux: melt 15 g butter, stir in 15 g flour and cook for 1 to 2 minutes. Whisk in the cream in three batches per 250 ml and simmer gently for 3 minutes.
- With cornflour: stir 1 teaspoon of cornflour smooth with a splash of cold water, add to the warm sauce and simmer gently for 1 to 2 minutes.
- By reducing: works mainly with double cream and cooking cream, less so with light cooking cream.
Frequently asked questions about cream
Can I whip cooking cream?
No. There is too little fat in it. Use double cream if you want to whip cream.
Can I replace double cream with cooking cream?
In a sauce or soup, yes, the sauce just becomes a little thinner. Not for whipping, mousse or ganache.
Can I replace cream with milk?
In sauces and soups this works with some extra binding, for example a light roux or cornflour. The result is less rich in flavour.
Can I freeze cream?
You can, but the structure changes: after thawing, cream is grainy and can no longer be whipped. Use it afterwards only in cooked dishes.
How long does cream keep once opened?
Follow the date and the advice on the pack. Once opened, cream usually keeps only a few days in the fridge. Smell and look before use.
Cream at a glance
- The difference lies mainly in the fat percentage: double cream at least 35%, cooking cream 15 to 20%, light cooking cream 5 to 10%.
- Only double cream can be whipped.
- Cooking cream is made for the pan and hardly splits.
- Light cooking cream is thinner and often needs extra binding.
- Cream splits through little fat, acid and hard boiling.
- Add acid only at the end, off the heat.
- Bind a light sauce with a roux or cornflour.
Remember this
You do not choose the right cream by the label, but by what you want to do with it. Double cream for whipping and rich sauces, cooking cream for everything that goes in the pan, light cooking cream when it needs to be lighter, with some extra binding. Once you know the fat percentage, you understand why a sauce works or splits.
