A long time ago, pre BIR, I'd been cooking Indian without fenugreek and enjoying it. My wife wanted to cook a dish from a recipe that called for fenugreek. We had a glass jam jar full of seeds that had sat unused for ages so I took the required amount and ground them for her using a mortar and pestle. I still remember the senses being lit up by the dish. I don't remember what the dish was but I remember the fenugreek aroma and taste.
Also pre BIR, I had never heard of Kasoori Methi. The aroma of these two ingredients from the same plant mean Indian to me now. I love the stuff.
