"1. Stare at the food you have to eat, and push it over so it does not touch any other food on the plate. Take a bite of something else, and with your fork, push the 'hated' food around, as if you are going eat it. While playing with it, think to yourself, "It isn't going to kill me."
2. Take a forkful of more food on your plate, and again, push around the 'dreaded' food so it looks like you have eaten some. Make sure that when you push it, the plate shows through so it looks like some of it is gone.
3. If the food is soft, try adding it to another soft food on your plate, so that you do not taste it as much.
4. If it is solid food, then add a condiment to kill the taste.
5. Try to seem as if you enjoying your meal, so your hostess will not be offended, but keep pushing the hated food around to look as if you are eating it.
6. If it is solid food, then cut it into very tiny pieces so you won't choke, then maybe pick up some potatoes with it, and chew it together so you won't taste it.
7. Don't breathe! It sounds silly but many studies suggest that a considerable portion (about 80%) of our sense of taste depends on our sense of smell. Just remember how dull some meals taste when you have a cold and a stuffy nose. Try not to smell the food and you should be fine. However, be prepared to experience the aftertaste when you finally do breathe through the nose.
Tips
You do not have to finish everything on your plate. When you feel you cannot stand another bite, then just push the plate slightly away from you, put the napkin on the plate and just sit till others finish.
If your hostess questions you, just tell her that you were not very hungry, but that it was delicious.
Warnings
Remember to chew your food well so that you do not choke."
