So, I was planning on making homemade aloo gobi for dinner this weekend, and the recipe calls for fenugreek. I grabbed a small bag of the seeds from the local bulk store and then came to find out that what I was supposed to get were the dried leaves. Sadly, the store doesn't carry that.

Can I use the seeds in substitution? Do they share a flavour profile? if so, do I toast them in the pan with the other whole spices?

I don't have a grinder or a mortal/pestle, so they'd have to stay whole.

Should I skip them all together? Is there another spice I can use instead?
