To put it simply, for the first idea i would love if we could make and cook pizzas in Vintage Story. I heavily enjoy the cooking aspects of the game and who doesnt love pizza it would be a great time for everyone.
For pizza of course we would need tomatos, once farmed i imagine they would be pressed in the fruitpress into tomato juice, perhaps then the tomato juice is mixed in a barrel with salt to produce puree. (Just incorporating already in game mechanics i apologise to any chefs out there)
The same way we prepare pies with the dough on a table, you would then add the puree and the pizza base would be produced then u add cheese and then any other toppings veg, meat or even fruit if your funky like that. Then it would be cooked in a fireclay oven once again similar to pies. pizza makes everything better, when your sad - pizza. when your happy - pizza, when your midway through a temporal storm and your entire garden is coated with drifters guess what pizza.
You know what as great as pizza. Tea. Tea would be a great addition into vintage story, ofc starting as the tea plant and leading on with the tea making process, this could give a temperature boost during the winter times etc. We could add honey to the tea and other toppings just to add slight saturation effect or maybe even a slight healing effect.
Anyway long story short
tea
pizza
