Should you have separate spices for milk and meat if you tend to shake the spices right into a pot, like a soup?
ArtScroll's The Laws of Kashrus
http://www.artscroll.com/Categories/kas.html says:
"Spice Shakers:
One must be concerned that steam from a cooking pot enters a spice shaker wile spices are being added to the pot. It may be advisable to use separate spice shakers for meat and dairy foods."
Well and good. Sounds like something advisable and laudable but not a slam dunk halachah that treifs up your kitchen otherwise. The nafka mina may be that you yourself may choose to use separate spice shakers [or to use separate measuring spoons and to pour the spice into the measuring spoon and from the measuring spoon into the soup; or if you are using a salt shaker, then pour some salt into your hand away from the soup, and from your hand into the soup], but when you go to peoples' houses [eg. Bubby Modern] and you see them not being makpid on separate salt shakers, it's not necessarily treif.
This comment in ArtScroll is based on a Badei Hashulchan [which, incidentally, is in my shul's beit hamidrash in the ezrat nashim; it's a light blue book], here in seif katan 165:
http://smg.photobucket.com/albums/v336/mel...=spices0001.jpgSounds like a slam dunk but notice he says, "nir'eh" = it's logical to conclude that it's advisable, rather than "this is the halachah and anyone who doesn't is a sinner who eats and feeds his guests treif".
The reason it isn't a slam dunk is that:
1. If the steam isn't yad soledet bo by the time it gets up to the salt shaker holes, the problems are mitigated.
2. Anything that gets in to the spice is possibly batel be-shishim: Even if you dropped an actual drop of milk into the salt which then got absorbed into the salt and isn't noticeable, you could possibly still use that salt for meat soup, so a bit of steam is even less of a problem.
3. The Rama to YD 92:8 is predicated on a teshuvah of the Ro"sh who was discussing a utensil above an oven. If you have an oven where you are cooking meat, and you have a dairy utensil above it, it's problematic because of the rising steam. However, there are two ways of understanding the Ro"sh. If the Ro'sh was speaking of ovens in those days where the oven had a narrow opening on the top and the dairy utensil is occluding that narrow opening, then the steam has nowhere to go but into the dairy utensil.
However, if we are speaking of a stove top, with an open pot, and the steam escaping into the air, it's less problematic and not necessarily analogous to the case the Ro"sh was speaking of and which the Rama was basing his ruling on.
It's just like you can't cook meat and dairy in our ovens at the same time since the oven is enclosed and the steam from the meat and the dairy mix even if the pots don't actually touch each other. But cooking meat and dairy at the same time on the stove top is a different situation since the steam from each is going into the open air and it's far less problematic.
