Is this Worm Kosher? The Kashrus of Tolayim In Fish

Educated kosher consumers are well aware that kosher fish require two characteristics, fins and scales. However, many are uninformed about the relevance of insects to the kashrus of fish.

Behind the Labels

(They are among the most difficult animals to restrain.)

What’s The Truth About…Glatt Kosher

Misconception : “Glatt Kosher” means something like “extra kosher” and applies to chicken and fish as well as meat.

Fact: Glatt is Yiddish for smooth, and in the context of kashrut it means that the lungs of the animal were smooth, without any adhesions that could potentially prohibit the animal as a treifa, an issue only applicable to animals, not fowl or non-meat products.

Misconception: Nikkur achoraim (rendering the hindquarters of an animal fit for kosher consumption) is a Sephardic practice that is banned by rabbinic fiat for Ashkenazim and thus not performed in the United States.
Fact: There is no such ban, and nikkur was practiced in many Ashkenazic communities into the twentieth century. The practice of some communities to refrain from eating hindquarters, owing to the difficulty in excising the forbidden sections, continues to exist among both Ashkenazim and Sephardim.

The Hole Truth: Together, Bagels & the OU Have an Unbeatable Personality

There is a definite connection between New Yorkers and the New York City bagel. New Yorkers are tough and firm on the outside but gentle and caring on the inside. A real New York City bagel too, is hard and crispy on the outside but moist and chewy on the inside. New Yorkers are shiny and flamboyant on the outside but good old down-to-earth and friendly on the inside. A real New York City bagel too, is burnished and slick on the outside but mushy and snug on the inside.

Dairy English Muffins

The OU certifies many brands of English Muffins which are labeled OU-D and many others that are OU-Pareve. In light of the issur to produce dairy bread (Shulchan Aruch 97:1), how can the OU certify muffins as dairy? The following two answers have been suggested to this question, and each is followed by Rav Schachter’s comments:
Muffins have a unique shape.

Kaskeset: Part Two
