Ajowan seeds are a great addition to the Indian bread naan. I find that once they are baked into the bread they lose a bit of that intense heat they normally carry.
Naan is possibly one of my favorite foods and I love experimenting with adding different things to it. If you don't plan on making your own naan you can always go to your local Indian restaurant and see if they have any ajowan seeds in stock. Usually it isn't a big deal for them to add some to your bread.
If you aren't able to try ajowan, even something like garlic naan is better than regular naan. It just adds a little something extra to an already amazing food.
