At least I know how to pronounce nuclear

I have no idea how to properly pronounce this sauce. I've had to ask for it at the grocery; I coughed mid-word to cover. It has too many letters, and that whole English-from-England thing? It doesn't allow for drawl.

In my mouth, the syllables become

unwieldy
adjective
Difficult to handle or manage.
