We are moving to a new community and we will be facing the following dilemma:
If/when we get invited for a meal (Shabbos dinner, ... ) how do I determine if the house is kosher?
When we started keeping kosher we got asked number of questions to determine that our house is kosher (i wish i remembered). But also people that knew us would endure long questions about halachot of kashrut so they knew we were not doing it kosher-style.
I am not talking about chumrot like chalav israel or particular schita, I am talking about much more basic level do they know and follow the basic halachot.
One approach is to dan everybody l'kaf zechut and accept all invitations until you learn about violation. The other approach is to decline all invitations - this is the approach of all Chabad families that I know.
I don't want this to be a discussion on how not to offend a fellow Jew which is important issue by itself. I would like this to be more halachic discussion of what makes a house kosher.
for example - 1) if you didn't tovel keilim - not sure, i think solid ok, liquid not ok 2) how you check your vegetables - i think not as long there is some check 3) which hechsherim you accept - as long they are on the list 4) where you go if you have question
one last point, an ashkenazi can eat in sefaradi house on Pesach from a pot where rice was cooked see this question. So in many cases you can follow different minhag outside of the house. So again what makes a house kosher on a very basic level.
would love to hear your opinions
