I also do love a curry, though it has been rare since diagnosis.
I had a lamb rogan josh (wetherspoons), with the yellow rice (pilau?), 4 poppadoms and mango chutney, along with 2 beers, and I found 2 hours after food I was at 5.2. Also a few weeks earlier, had a Salmon Tawa, which was very nice, with basmati from a takeaway, and that also didn't spike my levels, so curry definitely works for me, at least those I've tried so far.
Still trying to get into the cooking from scratch thing. One day, time will be on my side. And I will laugh, laugh like the gods of old.
