For a home meal , i say why not. If that is what you feel like making then go ahead. They are both starches , but if they are both prepared well, i think they would be enjoyed.
Yes, no reason not to if you want to.
Same reason American's fry potatoes. To eat and enjoy.
Yes,there is.The substitute in question is millet,a kind of grain grown in certain parts of China that has the same qualities of rice,but a different taste and appearance.
Yes a proper meal should be created and served by the same person, unless the meal is being served buffet style. However, if the guest(s) offers to help, it is acceptable for them to assist the maker of meal serve it.
Maybe, but it would depend on where you are. Rice is grown in temperate climates and needs a great deal of water ( it is planted in water). Potatoes are a tuber and grown in cooler climates and don't require as much water. If you were in an area that met the needs of both and kept them in different areas I suppose you could grow them on the same farm.
A tradional Thanksgiving meal usually has turkey, mash potatoes, stuffing, corn, and cranberries. There reason for that is because it is a tradition the pilgrims established at the first Thanksgiving. Pie is a hit or miss. Your thanksgiving will probably be the same with or with out pie.
Boil up some ham, cabbage, potatoes and carrots all in the same pot at the same time. Substitute corned beef for ham is desired.
these may serve the purpose of sustaining guests during the wait, in the same way that aperitifs are served as a drink before meals.
If they are the same size.
Nothing. A cornish pasty is a complete meal in itself. I would guess, designed as such for miners (in the same way as the sandwich was devised for use on the battlefield).
Rice is not the same as sugar - eating complex carbohydrates like rice and potatoes actually makes the body work harder for the sugar/energy than eating junk food like chips and candy. Also, most Asian countries eat plain rice, not rice with fattening sauces, and they eat healthy fish and veggies along with the rice.
Rice Tends to go back really quicky, All starychy foods do such as Pasta, Rice Potatoes etc. I wouldn't eat Rice 3 days old, 1-2 days old yes... If you really insist on making rice pudding then Maybe try the rice and see if its sour, if not go hard but maybe you want to eat the pudding the same day... Good Luck
NO it is not.
