Good try, but not Erech. Erech is a place, and 'him' indicates a person, plus you need a note. But you are right to be looking for a synonym of 'great joy' to start with.
You are on the right lines with cram - in fact, you are very close! Except that cram is 'biscuitish,' and flat, I think (like lembas). I realised when I was typing about flowers, bloomers, mounts etc. that there was just ONE Tolkienian instance for which I could use the 'loaf of bread' meaning of 'bloomer,' and thought I would do it before anyone else thought of it.
This particular loaf of bread is specifically connected to a troll. It isn't within the pages of LOTR, but it is in a very Hobbitish piece of work.
1. Troll’s bloomer.
2. Note great joy in a spin for him.
ORODRUIN: Portal met destruction twice (or is it thrice?) here.
BEORN: Suffered in confusion for him.
TROLL: Internet terror; bridge warden; Took-felled.
