Nobody uses the verb 'relish' anymore. It's a shame to me, because it's a terrific word. It's a way of expressing that you are greatly enjoying something. The problem is that the only time people use it is when they are making a pun based on the noun 'relish'.
That pun just isn't funny anymore. Comedy needs to be surprising and unexpected. If anybody ever uses 'relish' as a verb, you are guaranteed a pun is forthcoming.
Every now and then, play it straight. Sometimes the best surprise you can give is not making a twist at all.
