Using a Thickening Agent

For a thick, hot custard you need to add cornflour (cornstarch) as a thickener. The custard needs to come up to boiling point to thicken and to loose the taste of the uncooked starch, but the cornflour stabilizes the egg yolks so that they can tolerate higher temperatures without scrambling.

Thinning: Starch granules absorb water when heat is introduced, and they start to swell and bump into one another, thickening the mixture.

There are some cooking purists that say that to make proper custard you shouldn't need any flour or cornflour to aid thickening, you should let the egg yolks do all the work.

While it is still hot, add the gelatin from Step 1 and mix it in quickly to dissolve it. Using a strainer and a spatula, strain Step 8 well into a bowl. Place the bowl from Step 9 in a bowlful of ice water and use the spatula to stir the mixture. It will gradually thicken.

Custard is a decadent dessert made with eggs, milk, and sugar. Eggs are responsible for custard's thick and velvety texture, but some recipes (such as this one) call for thickeners such as cornstarch or arrowroot for extra richess.

You don't want the custard so cold that it sets and breaks up as you spread it. The easiest way to cool the custard is to put it into a large bowl in a sink of cold water. It will take about 15 minutes. If you want it to set, put it in the fridge for an hour.

Cornstarch often teams up with egg yolks to thicken a custard or pudding. Swapping in all-purpose or rice flour is your best bet here, since tapioca, potato starch, and arrowroot powder can be finicky with respect to cooking and holding.

If you notice lumps beginning to form in a custard, immediately pour it out of the hot pot into a bowl and pulse it with a handheld blender in five-second intervals until it is nearly smooth. This can take from 15 to 45 seconds, depending on how big the lumps are.

When used as a thickener, potato starch functions similarly to cornstarch. Often incorporated into dishes in the form of a slurry (starch dissolved in cold water), the potato starch particles swell and gelatinize, thickening sauces, puddings, custards, and more.

Can you make ready-made custard thicker? ›

I don't use eggs in my trifle custard I just put more custard powder in it. It works well and tastes similar to the egg one, I use extra vanilla. I bought a pot of supermarket ready made custard from the chiller, warmed it up, added a little cornflour to thicken as it was too thin for trifle. Worked really well.

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).

For a light thickening effect, use one teaspoon of gelatin per cup of liquid. For a firmer result, increase the amount of gelatin. To avoid clumping, always mix the gelatin with a small amount of liquid before adding it to the recipe.

3. Gently whisk/stir the paste mixture into the boiling milk. 4. Bring back to the boil; stir until the custard begins to thicken.

Yes it will - Bird's Original Custard Powder will thicken up with dairy alternatives such as Goats Milk, Soya Milk, Rice Milk and Lactose Free Milk.
