uneeq: “hello: It seems to me that the uniqueness of corn-bread would not meet the criteria of the Rashba, as a consumer would not see it as an indication of the corn-bread’s fleishig status, but rather of the uniqueness of corn-bread.
For consumers you are right. That would be in line with the Maharit brought down in the Pischei Tshuva. But for households it would be fine if everyone knows that the homemade corn-bread is fleishigs”
I disagree. When produced commercially no Siman is effective, as per the Maharit. The Rashba is referring to circumstances where a Siman is a valid solution, namely in the home, and even there its uniqueness must conclusively indicate its status.
BTW, according to this Maharit (and common sense experience), the practice in Israel of making cheese bourekas triangular is ineffective.
