Even some milk is safe to drink without boiling, like pasteurized milk. Raw milk should be boiled whenever possible. Pasteurized milk should be boiled if it has been stored at room temperature otherwise if stored in refrigerators then there is no need to boil, they are safe to drink.

2. Spout the milk into a big, clean pot

Choose a larger pot (in length) so there will be plenty of space as milk comes upward when it is boiled or sometimes overflow from a small pot. Clean the pot carefully, otherwise any residue might curdle your milk. It’s better to choose a pot to use only for milk. You need to pay extra attention to prevent burning or overflow.

Reasons of curdling

  •  Acidity and curdling

When milk is used in sauces, soups and other hot dishes it needs to be smooth rather than to curdle. So we have to be assure that food or meals, in which milk is added, must not contain any acidic element. Curdling of milk has very close relationship with acidity. Acids like acetic acid in vinegar or citrus acid in lemon, may bring curdling to the milk. So avoid strong acids in milk dishes. To lessen the effect of the acid, you may use a starch along with acid.

  • Seasoning at the End

Salt is another ingredient that can cause milk to curdle. The point is not to avoid the salt but you may add at the end, rather than cooking it with the salt already in it. Seasoning your sauces and soups at the very end is a good habit to get into anyway.

  •  Tempering of milk

Never, add cold milk directly into a hot liquid, but instead, flick small amounts of the hot liquid into the cold milk. When the milk gets warm, then add it into the hot liquid. This procedure is called tempering. Or you may simply heat the milk gently in a saucepan before adding it.

Types of milk and their nature of boiling

There are many types of milk but we’ll discuss some of the main categories. They are listed below:

Raw milk

It is also called as unpasteurized milk. It contains bacteria and other germs in large quantity so it is necessary to boil raw milk before drinking. As we know boiling process kills germs or microbes present in milk.

Whole milk

Whole milk is actually 3.5% milk fat and is normally less nutritious but more fat-free milk. It is not compulsory to boil this type of milk, one can drink it without boiling. It is likely to be curdled and make cheese from it as it can curdle very easily.

Skim milk

Skim milk is made when all the milk-fat is removed from whole milk, it contains around 0.1% fat. When curdling occurs, one of the reason can be the use of skim milk because it does not have enough fat content. Skim milk will curdle more than heavy cream, and low-fat creams.

Pros
  • Heat milk at low or medium flame to avoid curdling.
  • Use whole milk, instead of others, or heavy creams in hot dishes.
