please dont let the oil float. bring in a dietician and help them see that what they are used to, may not be a healthy thing for them.
they dont need to be annoyed. they just dont know any different.
it may be hard for them to change, but you can give it a good happy try and i am sure they will understand.
at least you and mr. Shikra will know that you gave your best effort to make it easy for them to change their eating habits and health-compromising preferences, for their own good.
but they have to let you take a chance.
listen, if you have your trustworthy sathee on your side, without resentful to the elders, things will go very very well - they will not only begin eating what you make, but would prefer how you will make it for them and enjoy good health as a family.
