Buttermilk is a by product of making butter from whole milk, slightly sour and is the liquid that is left when butter has been churned. Whole milk is milk that has normally been heated to pasteurise it and nothing is added or taken away. Buttermilk can be made at home (without the need to make butter!). To a cup of milk add a tablespoon of lemon juice, stand for about five minutes and use as required. Dispose when you've used what you have needed to use.
The main difference between buttermilk and milk is that buttermilk is more acidic and tangy in taste compared to regular milk. Buttermilk is also thicker in consistency and is often used in baking to help tenderize and add flavor to recipes.
Sour milk is milk that has gone bad and has a sour taste, while buttermilk is intentionally fermented and has a tangy flavor.
one is heavier than the other
It depends very much on the recipe in which the substitution is made. Buttermilk has a different acidity than whole milk, as well as less fat. Additional baking soda will need to be added and perhaps a bit of oil or butter, if buttermilk is substituted for whole milk.
There is a chemical difference between sour milk and buttermilk. The most traditional uses are buttermilk, vinegar, and wine. Sour milk can easily be configured to buttermilk by adding a bit of salt and vinegar. However marinate at your own risk while using sour milk to remove the taste of game, it has often times replace one bad taste for another.
Buttermilk has a different acidity than whole milk. If used in a cake mix that calls for whole or 2% milk, a teaspoon of baking soda should be added to balance the acid in the buttermilk.
Whole Milk
Do you mean 2% milk? There is a difference between 2% and whole milk. 2% contains 2% fat, and whole milk contains about 3.5 to 4% milk.
No, because that would mean that the whole milk was milk fat!
The main difference between half and half and whole milk is their fat content. Half and half contains about 10-18 fat, while whole milk contains around 3.25 fat. This means that half and half is richer and creamier than whole milk.
No, I wouldn't use it, you shouldn't really use spoiled milk in general. Buttermilk is kinda a form of spoiled milk but not really, it is more tart than regular milk (2%, whole milk etc).
Depends on the person.
