Why is it necessay to shake a bottle of salad dressing before adding it to salad?

Answer 1

Because it is concentrated and so the lighter stuff floats to the top (thats why its a lighter color) and the heavier ingredients sinks to the bottom (darker color) so you shake it to mix it so it doesn't taste gross. =P

Answer 2

Because the oil and vinegar in the dressing separate from each other and the mxture isn't blended. Also if there are herbs in the dressing they usually settle to the bottom of the bottle and aren't distributed evenly.

Answer 3

Because it is a mixture of vegetable oil, which is non polar, and vinegar, which is polar. Polar and non polar molecules do not mix. Its a chemical thing.

Answer 4

Because it consists of liquids such as oil and water, that have different densities. The two separate, and it is then required to shake to mix them back together.

Answer 5

You shake salad dressing to mix any ingredients that may have separated.

Answer 6

To mix the ingredients well where there may have been some separation.
