SEABROOKS!!
Best crisps EVER....pickled onion flavour that is.
Trouble is, they are a nightmare to get hold of. Only place I have found that sells them is the shop in the bus station in Pontefract which has now closed, a little corner shop in Leeds and Kwiksave in Bangor which is a bit of a treck.
I bought 42 packets a few years back when I was in Whales. They are seriously yummy, but if you eat too many packets they start to shred the crap out of your tastebuds and make your tongue sore.
You can actually buy them online, but you have to buy 48 packets and they tend to go out of date before I can get through them all
