Is there any type of customary or traditional foods for Mormons?

there are some typical ones... jello (particularly lime) salads, casaroles (sp?), and perhaps funeral potatos. not sure on that last one. oh, i almost forgot the pot roast sunday dinner! complete with potatos and carrots.

  Having been a Mormon all my life, all I can say is that I am not aware of any food that is particularly associated with my religion or with the culture associated therewith.

I've noticed that Jello molds and Casseroles are most commen. lol

Postum is the ONLY thing I can think of.

Let me expand on my brother's answer. I have live in more areas and am more widely traveled than he is. In all of my travels, I have found that what LDS eat really depends on the cultures from which they came. There really aren't any dietary choices that separate us from others among whom we live. Miss Zee lists some dishes that she associates with LDS cuisine. However, those are things that are particular to certain areas. (Lime Jello is the state food of Utah because of its association with that area.) However, down here on the Texas-Mexico Boarder, I have not once seen any kind of Jello salad at a church dinner. It's almost all tended towards Mexican cuisine because that is the dominant culture down here. So, because the Church is a world wide church, there really isn't anything thing that could be traditionally Mormon. There may be some dishes that are tradition to a certain region, but not to the Church as a whole.

hamburgers, lots of hamburgers

Honey, Manna, & Locusts!!! J/K

I don't think you can say that there are mormon dishes per-se, but there are cultural forces which create a particular range or type of foods.

For example: LDS families tend to be larger than average (ie: 4 or more children vs. the more common 1-2). Additionally, the doctrinal focus on family and traditional gender roles tend to mean that women/mothers try not to work outside the home if possible. This leads to larger families living on a budget with time for cooking by women. This may lead to certain types of foods: hamburgers instead of steak, salmon instead of lobster, etc. In other words, budget friendly dishes in addition to home made dishes instead of eating out or quick ready made meals. I have always noticed casseroles to be quite common among my fellow LDS friends/family.

Also, since many LDS families have roots in the west (Utah, Idaho, Arizona, California), the food they eat is a function of that region (tacos, chili, burritos, are all very common in most LDS households I have known). Southern cooking is not very common among most LDS families, unless they are converts who are from the South (like my in laws). Also, traditional english dishes more common in the northeast are not as common among LDS families who primarily hail from the west, etc.

However, there is one thing I find interesting:

Scones.

Ask anyone around the world what a scone is and they will describe a biscuit like bread, usually quite dense, and often made with various added ingredients for flavor (much like the diversity found in bagels). However, ask a mormon, especially one in Utah, and almost exclusively they will refer to a light, donut-like, fried bread often eaten with melted butter, honey, or fruit preserves. (similar to native american/navajo fried bread) In fact, there is a small restaraunt chain in Utah that makes all of its sandwiches from this "scone." (sconecutter)

Lime Jello salads. It's everywhere!!! I don't think they can have people over without it.

Not that I know of. There are plenty of stereotypical foods, but even those only pertain to the subset of the Saints that live in Utah.

Just like everyone else, what we eat is very much a product of our own family and culture.
