Explain in detail the principle of the Home Scale Ice Cream Processing from 1/2 cup + 4 table spoon instead of 400ml cold sweetened condensed milk , 2cups (450ml) heavy whipping cream (cold) and 1 teaspoon vanilla extract.

The principle behind using a specific measurement such as 1/2 cup + 4 tablespoons of sweetened condensed milk instead of 400ml is to ensure that you have the right balance of ingredients for making ice cream in a home setting.

When using a home scale to measure out ingredients, it allows for more precision and accuracy in the measurements. This is important because making ice cream is a science and getting the right balance of ingredients is crucial for achieving the desired texture and flavor.

In this case, using 1/2 cup + 4 tablespoons of sweetened condensed milk instead of 400ml ensures that you are using the correct amount of sweetness and creaminess in the ice cream base. The same goes for the heavy whipping cream and vanilla extract - using 2 cups (450ml) of heavy whipping cream and 1 teaspoon of vanilla extract ensures that you are getting the right balance of fats and flavor in the ice cream.

By following these specific measurements, you can create a delicious and creamy homemade ice cream that rivals store-bought varieties. The principle of using a home scale for measurement in this context is to ensure that you have the right balance of ingredients for the best results.
