Is cooking oil insoluble

Answer 1

Do you mean in water? Oil is not soluble in water, but you can use emulsification to mix oil and other liquids (including water) in order to produce a smooth result, such as in mayonnaise. To emulsify you need to suspend a liquid in another liquid. There are protocols to be observed and as anyone who has made mayonnaise or hollandaise sauces will have noticed, they can separate if not handled correctly, thus the oil splits from the other ingredients. This problem is easily fixed by basic techniques, but does illustrate the fact that oil isn't soluble. The same can be seen in sauces - such as Italian tomato sauces or curries, which use a lot of oil. The proportion of oil per serve means, in combination with the other ingredients, that they are very healthy foods, but the oil must be regularly stirred back into the sauce since it absorbs all the flavours.
