embafós

Una cosa embafosa o embafadora no és necessàriament dolça. Mireu la definició d'embafar:

embafar
v tr 1 Una menja o una beguda llevar l'apetit (d'algú), carregar-li l'estómac, per l'excés de dolçor, de greix o d'espessor.
2 fig Enutjar, una cosa, per l'excés d'artifici o la insistència.

Sorry, still working on old issues. Perhaps 'rich' and 'stodgy' might be good choices here.

Segons l'OALD:

rich
containing a lot of fat, butter, eggs, etc. and making you feel full quickly: a rich creamy sauce, a rich chocolate cake

stodgy
heavy and making you feel very full: stodgy puddings

They both seem to correspond pretty well to the definition of 'embafós' Jaume provides.

embafós
adj.
rich / stodgy
syn. - embafador

And cloying? That came out of trying to find a translation for the verb embafar - to cloy? It is pretty obscure but I can't offhand think of a synonym.
