Crème anglaise and crème pâtissière are both custards, but I use them for completely different structural jobs. Crème anglaise is a pourable sauce thickened mainly by egg proteins. Crème pâtissière, or pastry cream, is a filling whose body comes largely from gelatinised starch supported by eggs.
That single difference explains their cooking, texture and applications. Anglaise must remain fluid and delicate; pastry cream must become stable enough to hold inside a tart, éclair or mille-feuille.
The difference at a glance
- Crème anglaise: fluid sauce or base; pastry cream: thick filling.
- Crème anglaise: thickened mainly by egg coagulation; pastry cream: thickened by starch gelatinisation plus egg.
- Crème anglaise: cooked gently and stopped before curdling; pastry cream: cooked sufficiently to hydrate and cook the starch.
- Crème anglaise: usually based on milk or cream, yolks and sugar; pastry cream: dairy, eggs or yolks, sugar and starch.
- Crème anglaise: used for sauces, ice cream and bavarois; pastry cream: used for tarts, choux, mille-feuille and derivative creams.
- They are not direct substitutes because their flow and structural strength are different.
What crème anglaise is
Crème anglaise is a stirred custard made from dairy, egg yolks, sugar and flavouring. It has no substantial starch network in its classical form. The yolk proteins thicken the liquid as they unfold and form a delicate network during heating.
The finished sauce should coat lightly while remaining pourable. It is served with plated desserts and also acts as a base for ice cream, bavarois, crémeux and other preparations.
What crème pâtissière is
Pastry cream combines dairy, sugar, eggs or yolks and starch. Corn starch, flour or another appropriate starch supplies the main filling structure once it gelatinises during cooking.
The finished cream should be smooth and cohesive enough to pipe or spread. It must carry its own weight inside pastry without becoming rubbery or pasty on the palate.
How the ingredients differ
Both creams may contain milk, cream, yolks, sugar and vanilla, but starch changes the whole system. It raises viscosity, gives pastry cream more tolerance during cooking and creates body after chilling.
Butter may be added to pastry cream for richness, texture or a particular derivative, but butter is not what defines the cream. The defining difference is the starch-supported filling structure.
Whole eggs can appear in pastry cream formulas because starch and the intended firm texture make that system more forgiving. Crème anglaise is commonly yolk-based for a smooth, rich sauce, although formulas vary.
How crème anglaise thickens
As the custard heats, yolk proteins coagulate and increase viscosity. The useful window is narrow because the same process that thickens the sauce can continue into graininess and curdling.
I use moderate heat, continuous movement and observation. A thermometer is helpful, but the target depends on formula, equipment and the next application. I stop when the custard has reached the required coating and temperature for that recipe, then remove residual heat efficiently.
How pastry cream thickens
In pastry cream, starch granules absorb water and swell as they heat. The mixture becomes much thicker than anglaise and needs enough cooking to develop the starch fully.
Egg proteins still contribute, but starch changes the process and protects the system to a degree. The cream can be brought through a controlled boil according to the formula, something I would not do with a classical unstarch-thickened anglaise.
The exact cooking time depends on the starch type, quantity, batch size and heat transfer. I judge smoothness, viscosity and the absence of raw starch character rather than applying one number to every recipe.
Texture and consistency
Crème anglaise should flow. It may coat a spoon, but it is still a sauce and should spread naturally around a plated dessert.
Pastry cream should hold. When chilled and then smoothed for use, it must be pipeable and stable without feeling gummy. A formula that is merely thicker is not necessarily better; the cream must remain pleasant with the pastry around it.
How I cook crème anglaise
Direct heat control matters more than speed. A very high flame creates hot spots that can curdle part of the custard while the rest remains thin.
- Combine the dairy, yolks and sugar according to the formula without whipping unnecessary air into the mixture.
- Heat gently while stirring continuously across the base and corners of the pan.
- Watch both temperature and viscosity rather than relying only on time.
- Stop before the protein network tightens into visible curds.
- Strain when appropriate and cool or use immediately according to the next preparation.
How I cook pastry cream
Pastry cream can look thick before the starch is properly cooked. Stopping at the first sign of viscosity often leaves a raw taste or unstable texture.
- Disperse the starch completely before cooking.
- Temper or combine the dairy and egg mixture using the method appropriate to the formula.
- Whisk across the entire pan so the base does not scorch and no thick pockets remain.
- Once thickened, continue the controlled cook long enough for the chosen starch.
- Remove from heat, finish the formula and cool promptly in a shallow clean container.
Can crème anglaise replace pastry cream?
No, not directly. Anglaise will flow out of an éclair, soften a tart shell and disappear between mille-feuille layers because it does not have the filling structure those pastries require.
It can become part of another structured preparation. For example, an anglaise base can be combined with chocolate, gelatin or other components to create a crémeux or bavarois, but the resulting formula is no longer plain crème anglaise.
Can pastry cream replace crème anglaise?
A starch-thickened filling does not behave like a delicate sauce. Diluting pastry cream can reduce viscosity, but the starch remains and changes flavour release, mouthfeel and appearance.
If I need an anglaise, I make an anglaise. Choosing the correct system is more reliable than forcing one custard to imitate the other.
Uses for crème anglaise
- Sauce for plated desserts, cakes, puddings and fruit.
- Base for churned ice cream.
- Base for bavarois after adding the required gelatin and aerated component.
- Starting custard for certain chocolate crémeux formulas.
- A component in desserts where a fluid, rich dairy sauce is required.
Uses for pastry cream
- Filling for éclairs, profiteroles and other choux pastry.
- Layer in mille-feuille.
- Filling for fruit tarts.
- Component in Danish pastry, brioche and baked or post-bake fillings when the formula is suitable.
- Base for crème diplomate, crème mousseline and crème Chiboust.
The main derivative creams
Crème diplomate begins with pastry cream and is lightened with whipped cream, commonly with gelatin for additional stability. Crème mousseline combines pastry cream with butter for a richer, firmer cream. Crème Chiboust combines pastry cream with meringue and appropriate stabilisation.
Bavarois comes from a different route: a crème anglaise base is structured with gelatin and lightened with whipped cream. Knowing the parent custard helps me predict the derivative's texture.
Why crème anglaise curdles
A slightly over-thickened custard may sometimes be strained and blended for an immediate application, but visibly scrambled proteins cannot be restored to a truly perfect anglaise.
- Heat is too aggressive or uneven.
- The custard remains on residual heat after reaching its target.
- Stirring misses the base or corners of the pan.
- The egg-to-liquid balance has been changed.
- A small batch is cooked in a pan that transfers heat too rapidly.
Why crème anglaise stays thin
The custard may not have reached sufficient protein coagulation, or the formula may contain too little yolk for the intended texture. It can also appear thinner while very hot and gain some body as it cools.
I do not keep heating blindly. I compare the actual formula, temperature and coating behaviour because the distance between thin and curdled can be small.
Why pastry cream is lumpy
- Starch was not dispersed evenly before heating.
- The mixture was not whisked continuously as viscosity developed.
- Hot dairy was added too quickly to a poorly mixed egg-starch base.
- The pan has hot spots or the cream scorched on the bottom.
- Chilled pastry cream was used without smoothing it appropriately.
Why pastry cream becomes runny
Undercooked starch, an incorrect starch quantity, inaccurate weighing or added liquid can leave pastry cream too soft. Some formulas can also be weakened by enzyme activity if the starch system is not cooked correctly.
I diagnose the cause before adding more starch. Adding raw starch to finished cream produces lumps and an uncooked flavour; the formula and cooking process should be corrected at the source.
Cooling and storage
Both creams contain dairy and egg, so hygienic handling and prompt temperature control matter. I transfer finished pastry cream to a clean shallow container, cover its surface as required by the workflow and cool it quickly.
Crème anglaise intended for later use is also cooled promptly. Exact storage time depends on the recipe, production controls and local food-safety requirements; I do not judge safety from appearance alone.
My practical rule
I choose crème anglaise when I need a fluid egg-thickened custard or a base that will receive another structure. I choose crème pâtissière when I need a starch-supported filling that can be piped, layered or used as the base of another pastry cream.
They share dairy, eggs and sugar, but their architecture is different. Once I identify the job the custard must perform, the choice between them is straightforward.
