I am trying to re-create an extremely simple recipe for chicken & dumplings that my family used to make back in the states, but I can't seem to get the right flavor at all. Basically the dumplings were made with a mixture of either all purpose flour (or self rising, depending on what was on hand), water, and a couple tablespoons of oil.. The issue I am having is that so far I have tried 3 different types of flour and none of them has resulted in the flavor that the dumplings should be. Each time the texture is perfect, but the flavor is very bland and well..just terrible quite frankly. I have noticed that most Finnish flours are very fine as well in comparison to what we had back home, though I don't know if that has anything to do with flavor. I have been looking at some other posts here and saw that someone tried kakkuvehnäjauho for pancakes, and I wondered if that might also work for dumplings? What is the closest flour to all purpose flour here?
There are just so many flours to choose from when I check the aisles.. It's scary!

Thank you in advance for any assistance!
