We use our George Foreman quite a bit. I make toasted sarnies in it for a start. Now the butter knife. WTF. Why would you need a knife that has just ONE job, to whit, spread butter? Normal knives do that, as well as all other knifery related requirements. Butter knife? Frig me. GTF.
You're not missing much. Lots of cones about though if you miss the ones in Hull once they are gone. If you ever do make it this way let me know if you want advice on where to eat, have a pint etc.
I bought the Mrs a nutribullet last year. She desperately wanted one, so desperately that on the eve of its first anniversary it has never been out of the box. Bastard.
You don't need a special knife for butter when you take the butter out of the fridge and cut off slices to layer over the bread.
I bought a set of vintage fish knives on eBay, because they were engraved with an old Hull company's name .......................it's possible that I may have been drinking (weirdly I found them yesterday in the garage, I upgraded them so now they won't be used from a much better location!)
