Pastry cream adds a luscious richness and decadence to a wide array of sweet treats, from cream puffs to Italian lobster tails. However, there's one common misstep that even the most seasoned bakers can fall victim to — overcooking. While this creamy, delicious filling can set the stage for other components of the dessert to shine, overcooking is a frequent mistake that can detract from the overall quality of the dessert. When pastry cream is overcooked, the once silky-smooth texture becomes grainy and lumpy. Furthermore, the delicate flavors become muted, or even burnt. It's a heartbreaking outcome that can leave even the most meticulously crafted desserts feeling lackluster and disappointing.
So, why is it so easy to overcook pastry cream? The answer lies in its delicate nature. Pastry cream is essentially a custard made from milk, eggs, sugar, and flour or cornstarch. When heated, the eggs in the mixture coagulate, thickening the cream to a velvety consistency. However, if the cream is heated for too long or at too high a temperature, the eggs can become overcooked, resulting in a curdled, unpleasant texture — or even scrambled eggs in your cream. Nobody wants that.
Follow These Tips To Avoid Overcooking Pastry Cream
To avoid the dreaded fate of overcooked pastry cream, it's essential to exercise caution and precision throughout the cooking process. To help minimize the risk, keepa close eye on the temperatureas it cooks. Use low to medium heat and stir continuously to prevent hot spots and ensure even cooking. A heavy-bottomed saucepan distributes heat more evenly, reducing the likelihood of scorching or overheating the cream, too.
Pastry cream is ready when it coats the back of a spoon like pudding or has large, bursting bubbles that form slowly. Avoid cooking it beyond this point. As soon as the pastry cream reaches the desired consistency, remove it from the heat and transfer it to a bowl to cool. This helps to bring the cooking process to an immediate stop and prevent further thickening. If you notice any lumps or curdled bits in your pastry cream, you can strain it through a fine-mesh sieve to remove them and achieve a smoother texture. By following these tips and exercising care and attention to detail, you can ensure that your DIY pastry cream turns out perfectly every time.

Runny pastry cream most often comes from undercooking the egg yolk mixture. If you remove it from the heat too soon, the amylase in the egg yolks won't break down and will prevent the cream from fully setting. If you find your crème pâtissière is too thin, return to heat and bring to a boil over medium heat to thicken.
If your Crème pâtissière looks grainy, it was cooked at too high of a heat, causing the egg yolks to cook and curdle. If this happens, even passing it through a sieve won't help as some of the curdled egg will disperse through the custard making it grainy.
Starch. Starch thickens pastry cream. Most recipes incorporate flour, cornstarch, or a mix of the two. I found that flour produced a thicker, heavier texture and imparted an undesirable “floury” taste.
If your custard, creme patissier or creme anglaise has lumps or is starting to curdle, whack an ice cube in it then give it a quick blitz in the blender. Problem solved!
Pastry cream has flour or cornstarch added to it and, therefore, must come to a boil in order to cook out that starchy flavor. Because of this, pastry cream is quite a bit thicker and more pudding-like than anglaise.
When heated, the eggs in the mixture coagulate, thickening the cream to a velvety consistency. However, if the cream is heated for too long or at too high a temperature, the eggs can become overcooked, resulting in a curdled, unpleasant texture — or even scrambled eggs in your cream.
It's important that you add the hot milk slowly – this is called 'tempering' and it prevents the egg yolks from scrambling. If you added the boiling hot milk to the egg mixture all at once, the eggs would cook and curdle. This way, you're slowly increasing the temperature of the egg yolks while also diluting them.
However if the proteins are overcooked, either by using a temperature that is too high or just cooking for too long, then the proteins will come together so tightly that they will start to squeeze out water and this causes the weeping in an egg custard (or the scientific term for this is syneresis).
The basic ingredients of pastry cream include whole eggs and/or egg yolks or egg yolks only, sugar half and half or milk, cornstarch or flour and a flavoring agent. I have seen some recipes include butter, although not one of the original ingredients, it does add richness.
At its heart, pastry cream is a milk-based custard that's thickened with egg yolks and starch. Our pastry cream recipe uses both cornstarch and flour to deliver a luscious, thick texture.
Reheat the pastry cream slowly and bring it to boiling point.Once bubbling, reduce the heat and cook for another 1-2 minutes. Reason 2 - Adding too little corn starch or flour will result in a runny pastry cream.
If your banana cream pie is runny, it may be because the pudding mixture was not thickened properly. To fix this, you can cook the pudding mixture over low heat until it thickens, or add a thickener such as cornstarch or tapioca flour.
This can happen if you use too much fat or over mix the pastry. The pastry may be too dry and may not contain enough liquid to properly bind the fat and flour. This can also happen if self raising flour is used.
One way to fix it is to incorporate gelatin into the heavy cream as well and it might set the diplomat cream after folding it together with the slightly runny pastry cream.
