Iacisrmma – thank you for mentioning Rav Cohen’s sefer. I thought of that after I posted. That could also be a good place for LB to start. I haven’t really read his sefarim so much, but they seem to be short, to the point, and practical. I have the impression they go less in depth and bring less opinions than the other sefarim, but that might actually be what LB needs right now.
For the laws of cooking on Shabbos, there is a small illustrated booklet with pictures which makes the halachos easy to read and understand.
