Purple or Fingerling potatoes?

[HotPepperQueen]

Thanks for all the help! I believe I will be ordering All Blue potato sets and Fingerling sets from Jung. I will let all of you know in August how it goes! I am very very excited!

How do you use the different varieties of potatoes? I know Kennebec are for baking...Russets are mealy and tend to disentigrate when frying, where the red Pontiac dont. What's the best for mashed? The purple fingerlings..how do you fix them? I don't care for the gnarliness of Cobbler, but they are an old standby. Which kinds are mealy, which kinds are "oily"? Which are the best keepers? What are you #1 favorites and why?
