Hi there, Suz. Nice pic at the site, also. :)
Being a Sindarin Elf (of some antiquity, true), I can more or less reliably report that lembas were crunchy, not crumbly, had a taste that was almost sweet and almost dry but neither.
They are mostly on offer at Tulkas' Cookie Monster Shoppe in his treehouse.
Cheers!
Sounds like a Teacake to me! ;o)
