Sometimes the bottleneck is not the machines that produce items, or even not the miners. Sometimes it's just how you get items from A to B.
I have managed to double (on average) my SPM just by fixing some ancient, inefficient and janky setups for unloading items from machines/ores from trains etc., without having to add any more machines in most cases. Just fixing the low transport throughtput did that.
Since then I pay much more attention how the items are transported.
This Polish thing is most likely "paprykarz", which is fish meat with rice, tomato paste, spices etc.
Looks... Questionable, and is definitely an acquired taste, or one of those "I have once a year craving for a very specific type of food". In Poland it's usually rather cheap option for sustenance, used as a quick "I'm hungry and have 20 minutes of break".
I would like if the result was a sum of probabilities from other qualities. So for example, an output needs 4 inputs to make. 1 common 3 rare = 75% chance for rare, 25% for common. 1 common 1 rare 2 epic = 50% for epic, 25% each for rare and common. And so on. This would allow for intuitive quality mixing.
Granted, I didn't touch quality yet in my save, so I assume that currently it's "all rare inputs = rare output" 100% of the time?
