How this course works
Short and in order. Each lesson is about five minutes. They build on each other, so the early modules teach the concepts the later, practical ones assume — take them start to finish.
Video plus a written class. Every lesson pairs a short video with a full written class in plain English, so you can watch, read, or both.
Primary sources only. Each written class ends with its mekoros — Chumash, Gemara, Rishonim, Shulchan Aruch, and the poskim — so you can see exactly where every point comes from.
A question for your rav, not a ruling. These lessons teach the concepts and represent machlokes fairly; they don’t decide your case. Turn each one into a question for the rav whose rulings you follow. We recommend certification for any food business.
