Prepositions in ingredients

Hi, in Portuguese (and other Latin languages) it’s common to use a preposition between the ingredient unit and the ingredient name (for example: 100 gramas de mozzarella).

Is there a way to use it in WPRM without adding the preposition to the ingredient itself? I meand, I don’t want to write an ingredient as “de mozzarella”, only “mozzarella”, but I still want to make the “de” to appear on the ingredient list.

At least in Portuguese the preposition is probably always used and it’s probably always the same “de”. But there are a few cases in which it should not appear (for example for salt and pepper if I do not add exact quantities).

Thank you very much once more.
