Can you make regular scalloped potatoes in a crock pot using only flour and milk no cheese or canned soup?

Hi, if you cook the potatoes whole until just starting to get tender, then let them cook a little and peel and cut into slices. Put the slices into the crock pot in layers, adding any other flavor you like, for instance someone suggested onions. Onions and potatoes go really well together. Then in a saucepan melt some er and add the same amount of flour...and milk. Basically you are making a white sauce. It depends on how many potatoes and how full you want to make your crock pot on how much you make but generally speaking 2 tbs of er and 2 tbs of flour will thicken half a litre of milk to a nice consistency. Instead of salt use a stock powder called "Vegeta". It gives the white sauce a nice flavour. Of course any stock cube or powder will do but you will be amazed at how much flavour vegeta gives the sauce. (regular vegeta, not chicken or beef or seafood, it comes in a blue package or tin. pour over the potatoes and set the pot on high, when the white sauce seems to be getting hot you can turn it down to low for the day. You can make all this the night before and put it together and in the fridge then the next day put your crock pot on automatic, usually that means high at first and then low. Good luck.
