Hello Rabbi!

Could you please weigh in on Trader Joe’s frozen puff pastry sheets? I believe they are from France and not hechshered. Here are the ingredients:

First, Trader Joe’s puff pastry contains actual butter, and the only other ingredients are unbleached wheat flour, vinegar, water, and sea salt.

This is a seasonal item which runs out. I’ve never purchased it before and left it at the store yesterday. Are the butter or vinegar problematic?

Thank you.

Happy Chanukah
