Q: Smoked paprika need hechsher?
A: Yes; all smoked spices need a hechsher (cRc).
Q: I read that Mordechai was actually Esther’s husband, not her relative. Why didn’t they ever teach us that??
A: Probably because the straightforward reading of the Megillah – without the Talmud’s explanation – says that she was his orphaned cousin that he adopted as a daughter.
Q: According to the Talmud, if Esther really was married to Mordechai why does the Megillah say that he adopted her?
A: Just as G-d’s name is omitted from the entire Megillah, there are many other details which seem to be intentionally obscured (another example: Achasveirosh’s antisemitism is heavily de-emphasized, see Torah Nation). This is perhaps due to the fact that it was a book that was distributed throughout the kingdom – for Jews as well as Non-Jews, and it therefore might be discarded and not treated with the respect due a sacred text (therefore the Almighty’s name is omitted) and it had to be self-censored. If the humiliating fact that Esther became queen while she was already married to another man became public, there would be a great threat of Achashveirosh taking retribution on his Jewish subjects.
Q: Food Club Prunes are K-ORC (which is a hechsher I don’t usually use). Only ingredients are plums and potassium sorbate.
A: Prunes are OK even without a hechser (since the potassium sorbate, used to preserve moisture, is either synthetic or derived from berries or grain – and therefore could pose a problem for Passover).
