I accidentally put a cold milky (plastic) liquidizer into a hot pareve soup (which contained cooked onion) that was made in a meaty pot. The liquidizer is rarely used for actual milky foods.
Do I need to kasher the LIQUIDIZER?
(I’m grateful for the precious response to this question but the answer referred to the pot, not to the liquidizer itself).
What I wrote before also applies to the liquidizer, because the pot was not a bein yomo. Seehttp://dinonline.org/2016/12/05/milky-liquidiser-in-pareve-soup-cooked-in-meaty-pot/
