Having moved around Britain fairly frequently in the past, I have found that the taste of potatoes varies a lot between soils and local climate. In our allotments before we moved here, we always grew Desiree. We tried them here for the first couple of years but found them tasteless and unhappy in our ground.
This year, on our rich basalt volcanic soil (the volcanoes are long dead) in southern Scotland, we are growing Athlete, Rooster and Carolus, which are all blight resistant (our place was once a potato farm and the blight still lurks). We grew these same varieties last year and were well pleased with both the taste and the yield. All these are available through the big catalogues such as DT Brown and T&M.
However, your choice depends on what you want - salad potatoes, earlies, roasters, mashers, main crop storers, fluffy or waxy and so on. I usually try one different variety each year but as we were content with last years crop I just repeated it.
