I keep getting confused when you type PB as it's the shorthand for the website I write for - I keep getting ready to launch into a defence of it!
I love peanut butter in chocolate.
I too enjoy it, but only if it's done right.
Here in the States, we have Resee's cups which have INCREDIBLY dry peanut butter inside.
The cups themselves aren't terrible, but it's that chalky peanut butter that ruins it all.
