Charoses: Bricks, Straws, and Blood

I always marvel at the plethora of new Pesach products that come out every year. Canned charoses is one that I haven’t seen until this year. Of course, many remember with nostalgia the box from the Yeshiva of Telshe that used to arrive in the mail with two silver pouches of prepared charoses. The pouch came with instructions: “To give the Haroset its proper texture, add a bit of wine, mix with fork.” At the time of this writing, one such box is being sold on eBay and it currently has 13 bids.
Tosfos and the Rambam rule that charoses is actually a bona fide mitzvah, more than just a custom. Therefore, scrupulous individuals take the opportunity to be personally involved in creating this mitzvah dip. The Rambam writes in his commentary to Mishnayos that, according to the accepted opinion that charoses is a mitzvah, one should actually recite a separate bracha over it: “Al achilas charoses.” However, he later modified his opinion and rules that no special bracha is recited.
