Musings of a home cook - Tonight I added dashes of cumin to an oven chimichangas recipe because we've "discovered" that for us cumin is a signature "Mexican" flavor.
What are Signature Flavors in your mind for other countries? Here are a few more I've come up with.
Almond - Scandinavian / Swedish / Norwegian
Cardamom - on it's own, Scandinavian, with other spices - Chinese
Five Spice - Chinese
Lemon/Oregano combo - Greek
