Yes, you have to say it carefully ;)
I am currently in the process of chitting potatoes (putting them in a light place to get shoots so they grow faster when they go into the ground). They are happily sitting in an egg carton on the window sill and have some nice sprouts on them.
I decided not to go for expensive seed potatoes from a catalogue like last year which ended up being slug food. Ok, to be honest it was mainly the leaves - still got a few potatoes out of them but not enough to justify spending a lot of money on them. So instead I used a few potatoes from the ones I bought from the supermarket, a variety called "Anya". I know, I know, you are not supposed to do that. They are supposed to certified disease-free, from a reputable dealer. But this way I end up with as few as I want to plant, for a fraction of the price, even if it comes to nothing. I'll treat it as an experiment and plant them in the large pot I used last year (although that proved to be an easy and juicy target for the slugs) instead of the ground. Anyway they are hopefully going in around mid-March, perhaps even a bit earlier if the weather decides to warm up.
