I don't know about you guys, but when I go to the grocery store and peaches are too expensive, I buy oranges or whatever else is on sale.

Sure, so, if you're looking to bake an apple cake, you wouldn't hesitate to make it with juicy peaches or oranges instead and stuff the result in your oven

(you definitely must have amazing products to clean it afterward) ? Or if you're looking to have a glass of fancy sparkling wine with your girlfriend, and some strawberries along, you'd switch them out with bananas if strawberries are too expensive ? Very romantic result too, I'm sure
Even from a factory / production perspective (
which is more on topic), try making wine by pressing oranges instead of grapes, or citric acid with anything else than lemon, and you're sure to have very fun results

(
also to go bankrupt fast)
That's what I meant by "when they're not starving, people are picky". It's not only because they become spoiled brats, but also because their expectations towards food divert from "purely filling the stomach", to encompass
-culinary- arts, regional traditions, visual and olfactive effects, mood suggestions, etc. They consider investing themselves into more fancy preparations, and some of them simply don't work with just "any" food product. Some preparations so fancy and creative, that they won't even neccesarly stay in the food category: lemons used in detergents, eggs in
-or directly as- shampoo, vegetable starch used to stiffen textile fabrics, etc. In that sense, I definitely consider the various fruit product of the game to be quite unswappable with each other because of their very different shapes, and physical properties
-I must however admit that citric acid, starch, and many of the uses making them so different, are absent from the product line-. Between different species of fishes, the same is true, but much less than for fruits, or vegies. Bah it's ok... Here, have a grape split (bananas were too expensive

).
