What is custard and how to make it

Custard is a sweet or savory creamy dessert with a rich consistency. It dates back to the Middle Ages when it was used as a filling for a tart or flan in the United Kingdom. The word “custard” is derived from the French word “croustade,” which means a tart with a crust. 

After the 16th century, when fruit creams became widespread, people started making custard as an individual dish rather than filling a crust. Today, most people enjoy custard on its own, but some still use it as a filling for pies, tarts, éclairs, quiches, and cream puffs.

The custard flavor can be best described as sweet and egg-y. However, savory custards are also famous and can be used to fill quiches. Most people enjoy sweet custards and prefer adding dessert flavors, such as vanilla and strawberry, to custard. 

Custard texture is creamy and velvety. Some people like to keep a pouring consistency, whereas others prefer thicker custards filled in cream puffs, tarts, and éclairs. The higher the percentage of butterfat and egg yolk, the thicker and creamier the texture is.

Types of Custard

There are mainly 6 types of custards. They include:

1. Baked Custard

Traditionally, the baked custard is cooked in a water bath. The water bath slowly transfers the heat from the oven to the custard mixture and prevents it from curdling. The American version of custard is also a baked dessert made of eggs, milk, nutmeg, vanilla, and sugar.

2. Egg Custard

Usually consists of eggs, milk, and sugar. The custard becomes thicker and richer if more egg yolks are added or if cream is used instead of milk. Many people use cornstarch to obtain the thick consistency, but with egg custards, people use egg yolks.

3. Refrigerated Custard

Mostly made of starch and milk solids, there are three main types of refrigerated custard: premium, regular and low-fat. The premium variety is rich and creamy and has a fat content of approximately 6%. Regular custard has a fat content between 1% and 3%, and the low-fat custard has a fat content between 0% and 1%.

4. Powdered Custard

Powdered custard is produced using wheat starch, maize, sugar, salt, flavoring, and coloring. It is combined with sugar and milk and then stirred overheat. It thickens as the starch particles expand due to heat and moisture.

5. Stirred Custard

Sweet, stirred custards are either prepared on a stovetop or in a double boiler. The custard is then mixed until it is thick enough to smear the back of a spoon.

6. Pastry Cream Custard

Pastry cream is made from sugar, milk, eggs, and flour. Flour is added to the custard to prevent curdling and make it firm. This thick custard is used to fill pastries, tarts, cream puffs, and other desserts.

How is Custard Made?

Custard is mainly made from eggs, milk, and sugar. You can cook it in an oven or on a stovetop. 

Sometimes a starch, such as flour or cornstarch, is added to the custard to prevent curdling and stabilize it. You don’t need as many eggs when you add flour or cornstarch. Flavors such as chocolate, vanilla, strawberry, and mango can also be added to enrich the taste.

In many South Asian countries, the powdered custard is eaten with fresh fruits, sponge cake, Jell-O, and whipped cream. This dish is called “fruit trifle” and is a popular way of serving custard.

How to Store Custard

The ideal way to store custard is to refrigerate it. You can refrigerate just-cooked or baked custard, but let it cool for about 5 to 10 minutes at room temperature. When cooled, cover it with plastic wrap.

Make sure the plastic wrap touches the custard’s surface to prevent the milk proteins from forming a thin crust on top of the custard when it’s in the refrigerator. Eat within 2 to 3 days to enjoy the prime custard texture and flavor.
