The OU has a very nice program called Halacha Yomi that consists of a daily (except legal holidays) email that covers a broad range of halachic topics. ( More about this program and to subscribe here. ) In a recent Halachi Yom, the topic of food made with even small amounts of meat or wine was discussed. My wife and I read and discuss them in the morning during breakfast. After reading/learning through the email, my wife asked, "So what about grape jelly?" Hmmm... good question. I never thought about it, nor had I seen it discussed. I decided to do some research. In the old days, I would have just Googled for any references to grape jelly, nine days, Tisha b'Av, etc. Then I would have perused the hits until I found something relevant/interesting. I like to do research before talking with the dayan so I don't waste his time. Now we have AI, so that saves me time also, right? Well... Let me walk you through my journey. I decided to start my research be looking for the b...

Everyone loves a good leniency. There is a famous dictum that applies to all areas of halacha: ספק דרבנן לקולא, ספק דאורייתא לחומרא/Where an irresolvable doubt is present: with regard to Rabbinic decrees, we rule leniently; with regard to Torah prohibition, we rule stringently. A famous example that comes up annually is respect to counting the Omer when one has definitely missed a day. On the one hand, it might be that the counting of each and every day is the fulfillment of a Torah requirement; therefore, we continue to count the rest of the days. On the other hand, it might not be a mitzvah at all once a day has been missed, in which case it would be innappropriate to make a bracha. Since (nearly) all brachos are mandated by Rabbinic decree, one does not make the bracha before counting the days of the Omer after the missed day. So far, so good. Boringly straightforward at this point in my learning. Imagine my surprise, then, when I learned (Yoreh Dea 92:7) that one can be lenient...

There is very little rhyme or reason for how a topic for a TftD gets chosen. Basically, I learn something, think, "Oh, cool!" and then write it up.... as soon as I have time, which has been quite limited recently. As a consequence, I have a growing backlog of "oh cool" thoughts that I am itching to publish. That being the case, I may as well choose one that goes together with the epoch in which we once again find ourselves—the Three Weeks—which began with the fast of שבעה עשר בתמוז and culminates with the commemoration of the destruction of the Temple, may it be rebuilt soon and in our lifetime, on תשעה באב. I was discussing a question on Chumash this last week, and of course we looked at the רש''י on that verse. After realizing that I had fully understood what רש''י was saying, I commented that someday I need to actually learn רש''י and not just read it every week. The expression "I saw an interesting רש''י this week" is ju...
