Sorry, Pat, you can put me down as one who didn't know the word and therefore didn't find it.
I'm not very good at names of food and ingredients.
I'll just have to take your word for it that it is likely to be known by lots of people. My visits to Greek-speaking countries took place many years ago.
I fully agree with you about miasmata. I assume this is a Greek plural form.
I would have thought that miasma was a 'non-count' noun which wouldn't normally have a plural.
COD, however, does give miasmas, ie with the regular English plural inflexion.
Interestingly, in another recent game automata, a similar plural form, was given 'uncommon'
COD, by the way, gives both automatons and automata as the plural of automaton.
