Righ on!

By what you said previously, yes.

Only that here in northeast region is mistura (with s though I don´t know if the writer of the post is from here or there).

In the south, of course, can be mixtura ,I know of northeast mores a tad more than of south.

I might be wrong, yet, by assuming that the questioner is from northeast, I admit.

Thanks by your contribution.
