Can we nail this one on the head and put it in the FAQ perhaps so that it doesn't rear its ugly head again?
If I cook 10 pots of curry all with exactly the same ingredients, including the spices, and I then pour them all into one big pot, the big pot of curry will taste exactly the same as the curry from the smaller pots, right? If anyone disagrees with this then you urgently need to go on a basic science course.
So, to the question "when scaling up a recipe, do I scale up the ingredients proportionally", the answer is a very incontrovertible YES!
The only thing you would have to watch out for is different evaporation rates when cooking in different size pots.
