Alrik, in order to make it easier, I write "ä" = ae, "ö" = oe, "ü" = ue. This is ok IMO and IIRC allowed in the internet/mail language.

What about this?
Der Luegner = the liar, masculine <img src="/ubbthreads/images/graemlins/devil.gif" alt="" /> die Luegnerin = female liar (here you see how endings can change the gender)
der Esel = the donkey, masculine ("die Eselin" or "die Eselstute" for the female)
der Essig = vinegar, masculine, pronoun here is "er" = it, nice, huh?
das Salz = salt, neutral, pronoun is "es" = it, logical
der Pfeffer = pepper, masculine, pronoun is "er" = it for you
die Daemmerung = dawn/dusk, female - to specify this, you can use another wonderful German speciality: compounds!
die Morgendaemmerung = dawn, female (but: der Morgen = morning, masculine) <img src="/ubbthreads/images/graemlins/delight.gif" alt="" />
die Abenddaemmerung = dusk, female (but: der Abend = evening, masculine) <img src="/ubbthreads/images/graemlins/delight.gif" alt="" /> <img src="/ubbthreads/images/graemlins/delight.gif" alt="" />
The rule for this is: Gender is defined by the second part of the composite noun and "Daemmerung" is feminine
