Vegemite/Marmite. Awesome substitute to make soups and stews richer for vegetarians (versus beef broth).

Nori seaweed. It helps with stocks, rolling sushi, and also, when ground up, in seasoning edibles. It's very versatile and has a unique flavor profile especially when toasted.

I don't think many people know you can get marrow bones at Safeway. Anytime I want to do something fun at home, I get them because they have so many uses. I've turned them into vinaigrettes, smoked them, and made butter or just a roast served with bread and roasted garlic.
