Finally, an important topic in the CR.
Matjas is my favorite, with Schmaltz a close second. Pickled is bal tashchis.
While some of the new types/flavors are tasty, I must make a Macha’ah because they are not part of the Mesorah. [That said, I will not turn down a piece of Jalapeno herring. The pepper-crusted ones are also delicious].
