I've never had peanut butter before
I did try Nutella on a homemade pancake once and from that moment on I knew I was gay
Peanut butter is good.
I prefer smooth, but crunchy (has pieces of peanut in it) has its place too.
Try Sunpat peanut butter. It's more expensive than supermarket home-brands, but it's probably one of the best available in the UK.
That said, even Lidl's peanut butter isn't bad.
Also, Peanut Butter doesn't contain actual butter, so forget all those people at junior school who told me I didn't need to butter my peanut butter sandwich, because it already contained butter!
