I honestly love Ready Salted.
Which in the UK makes me a bit of a plain Jane where it's the boring flavour. But seriously in Ireland Cheese & Onion is their "plain" flavour - finding Ready Salted is like trying to find a needle in a haystack.
My Nan thought I was bonkers last time I was back in the UK with a very simple and clear shopping list of:
1) Crumpets
2) As many bags of Walkers Ready Salted as possible
