I've been contemplating how the wasteland would do holiday foods, since they don't have access to a lot of the classic holiday spices like cinnamon, nutmeg, allspice, and vanilla. I'm going to try and stick as close as I can to food we actually see in game, across all the games, with one notable exception. This is sort of a spiritual successor to my last wasteland food headcanon post, and while originally I just started typing this on the couch while having coffee, it grew extremely out of control.
I'm going to leave out the really obvious things like mashed potatoes because... Well I don't have all day, and I don't want to condescend to you. But I am fascinated by the potential wasteland diet, and the fallout games give us VERY LITTLE. I'm sorry, but I don't want to believe wastelanders are eating unseasoned roach out of the shell.
There are still plenty of ingredients to make reasonable approximations of your favorite holiday foods, so here are my Wasteland Holiday Food Headcanons
The Basics - What do wastelanders have access to?
While raw ingredients like flour and sugar don't appear in game, the fact that things like sweet rolls exist confirms that they have access to those raw ingredients (and I am not that much of a fucking pedant). They'd also have to have some sort of leavening agent (likely baking powder, as cream of tartar, an acid used in baking, is a byproduct of winemaking, which we know they do in the wasteland). I'm also going to allow myself a few things we don't see in game, but would be logical for wastelanders to do, like making jams, preserves, cheese, etc.
Wild yeasts can also be collected off plants, so we'll be generous and assume they have access to yeast cultures. We also know they have to have yeast, because again - brewing alcohol like beer requires yeast. Furthermore, moonshine requires sugar, which brings me to my next point.
While wastelanders don't have access to raw refined sugar, they DO have access to sweeteners (that's the sweet in sweet roll). Corn crops means corn syrup. They'd also likely be using maple syrup or honey as a sweetener. So we know they have access to milk, which means having cream and butter, we know they have flour and salt, we know they have water. We also know they have eggs, thanks to the chickens in the Far Harbor DLC.
Let's start with the easiest, most classic staple of humanity:
While bread isn't exactly the first thing I think of when it comes to Holidays, Humans Like Carb, especially when it's cold outside. What does a wastelander's bread look like?
The standard loaf of bread in the wasteland is probably a sourdough, since sourdough starters will outlast the heat death of the universe. Yeast for the bread can be taken from the air around you, and they're so low maintenance you can forget about them for months and still revive them. However, sourdough isn't necessarily festive.
Sweet yeasted breads like challah, or enriched brioche are very possible in the wastelander's diet. Razorgrain seems typically closer to a rye than a wheat, so this is going to affect flavor and texture, but it's not going to stop anyone from mixing in different fruits, or glazing their loafs with a simple sweet glaze. One could also just make a literal sweet bread slathered in preserves.
Whatever you want, bread's got your back.
This one is going up near the top because I'm going to present a couple ideas that are going to be important to the integrity of the rest of the post.
Chicory root. I'm gonna break my own rules here by using a plant that's not mentioned in game, but I don't care. I have long contemplated where wastelanders are getting their coffee, since there's no way those tins have survived 200+ years, and then it recently came to me. It's Chicory root. Chicory is a coffee substitute that's been used in America as a coffee substitute since the Civil War, and can be roasted and brewed as an earthy, caffeine free beverage. Sweeter variations exist, and in 200 years, I can believe that caffeinated mutations exist.
Granted, chicory is probably a year round drink and not strictly holiday related, but with some wasteland marshmallows, we can think of it as a tasty hot chocolate substitute.
Tea is another thing given to us by fo76, but that doesn't matter, I was always a tea truther. Again, not holiday specific, but everyone likes a hot drink when it's cold and snowy outside.
Eggnog is possible, but it's going to lack the typical holiday flavor of cinnamon and nutmeg. It's also going to be boozy as fuck. The booze helps to preserve the raw egg, and depending on the alcohol content, it could keep for up to a month in the fridge. (Yeah, it can be cooked but where's the fun in that?) Wasteland eggnog is definitely sweet, perhaps flavored with fruit syrups or even roasted chicory root.
Spiced wine/rum. This is where I loosen the reins a little. The spices in spiced wine or rum typically refer to cinnamon, oranges, cloves, allspice, and nutmeg. All of which we have previously decided the wasteland doesn't have access to. But humans like spices! Historically, we have done a lot to obtain spices to flavor our food! People don't want to eat bland food, so I do not believe that for the last 2 centuries, wastelanders have been contenting themselves with unseasoned meat and drinks. So this is my second important rulebreaking caveat:
As you can brew tea with various plants found in and around the wasteland, I don't think it's unreasonable to assume that you can harvest some sort of spice analog. (Also you use hubflowers to make meth, so... There's gotta be something in there. Maybe caffeine). However you wish to interpret the flavors of these spices, and where exactly they come from, is up to you. I am choosing to interpret them based on the buffs they give your character as consumable items - for example, fever blossom tea gives you an AP boost, which could be read into as being caffeinated/spicy - maybe even close to cinnamon. The world is your oyster.
The spice in spiced alcohol could easily refer to being brewed with various tea leaves, or spices harvested from these plants, and sweetened with fruit and fruit syrup.
Remember corn syrup? I remember corn syrup. Let me tell you that wastelanders are making a shit ton of candy.
Corn syrup + water + heat. It's easy, it's versatile. Hard candies and candied fruits or nuts are just taken to the hard crack stage, while soft candies like caramels or marshmallows are taken to soft ball. I imagine that they flavor their candies with different fruit syrups and concentrates. Again, for flavoring we can look to concentrates made out of tea leaves. Tarberry, mutfruit, cranberry, and apple are all flavor possibilities. While we never SEE nuts as a consumable item, we can assume if they exist they're being thrown in to make brittles.
While the old marshmallow was made with the sap of the marshmallow root, the modern marshmallow is just made with sugar, gelatin, and water that's been whipped to hell. With a livestock industry, wastelanders would certainly have access to gelatin, and they have corn syrup. Again, you could say they add some juice concentrate to flavor it, as they have no access to vanilla (and the gelatin would impact the flavor somewhat).
So we've already covered their access to raw ingredients to make bread. You can use these same ingredients to make basically any other baked good. The lack of refined sugar is going to change the texture, resulting in chewier, softer cookies, but they would be by no means inedible.
If there's too much corn syrup, maple syrup and honey are good substitutes. I suspect maple would become a central flavor and ingredient (also who doesn't love a maple cookie?)
You could make an unsweetened shortbread out of butter, flour, and salt, which would be closer to the typical modern texture, and then throw whatever kind of sweetened confection you want on top, be it maple glaze, honey, or fruit jam. Whatever!
Apples are real, according to fo3 and fnv, so apple pie is back, albeit diminished without spices like cinnamon. Gourds return to us pumpkin pie, and you could reasonably make some sort of sweet tato pie (potatoes distinct from tatoes are mentioned in the dialogue and I think you can find raw potatoes in fnv, so it's not unreasonable to say sweet potatoes/yams exist out there, but who knows).
Fruitcake exists. I know it does. Heavily, heavily alcoholic, once again to preserve shelf life. Packed with all sorts of dried fruit like tarberry and mutfruit. Rum cake - wait hold on. Rum is real. The canonization of rum changes the game.
Rum is alcohol brewed with sugarcane. Sugarcane means sugar. SUGAR IS BACK ON THE MENU, BOYS! POST CANCELLED!
Miscellaneous Holiday Food
These are some honorable mentions I'm throwing in for fun variety to the wasteland diet.
I thank fo76 for returning to us the mighty cranberry, which means sweet cranberry dishes are back on the menu - perhaps our single surviving modern analog. The controversial cranberry sauce, sweet cranberry bread (There is a notable absence of citrus in Fallout, which I find hard to believe considering the slutty nature of the citrus family, but it's out there somewhere, I know it...)
Latkes - who doesn't love a latke with some applesauce or sweet cream?
Cheese - they're making so much cheese. SO MUCH CHEESE. Cheese keeps forever, is calorie dense, and you can throw all sorts of shit into it for flavor variety.
Gingerbread - look, I backed myself into a corner by assuming they didn't have access to refined sugar and wrote a whole post about it, but they've got rum, and that means they've got sugar, and that means they've got molasses. You could argue the scarcity of raw sugar, and perhaps I will, but that's a different post. Who cares. The ginger in gingerbread probably isn't ginger - pick whatever in game spice analog you want, be it ash flower or fever blossom.
Wait. There's lemonade on the consumables list for fo76. Citrus IS real. Jesus Christ. Post cancelled for real now, guys, I'm outta here
