Mine this year are a mix of what I have tried and liked and what my plot neighbours have tried and liked (and offered me a few to taste).
I've got Jazzy as a 2nd early - grew these last year and was very impressed. They can be harvested as new potatoes or left to bulk up, suffered almost zero slug damage and were hugely productive and very tasty. I have some in store that are just sprouting, so these are getting used up fast now. Not bad for a 2nd early to keep going this long though.
Sarpo Una - this is an interesting one I got given last year by a plot neighbour. You can grow is as a new potato and I am going to try a few in buckets in the greenhouse for extra early potatoes. My plot neighbour did this at home with great success. The ones in the plot can then be lifted as salad potatoes, or if you leave them they turn into floury baking spuds. I liked both versions I tasted
Blue Danube main crop - another of the Sarpo family and it has a blue skin, but is white inside. I was given some of these last year and told they made the best roasties ever. After trying them I had to agree - crispy outside, fluffy inside and great flavour
Even OH noticed and said they were especially good.
