Now, why on earth have Poles never pickled onions?
It is funny you still don`t understand the Polish culture after so many years. Poles don`t need pickled onions coz they enjoy other pickled stuff, like cucumbers, peppers or mushrooms. Do Brits eat them? No, they prefer pickled onions. Very stupid of them, I must say. :):)
As for never in your post, never say never in the forum coz you are wrong. Pickled onions are available.
The only time I ever had pickled onions was when they were in with Polish pickled pigs feet.
Yes, they are good for decoration but eating them is a crazy idea. Yuk.
