Adventurous, long-time high-end gourmet, altho we stop short of ridiculously excessive tasting menu restaurants like Alinea and Benu, as Spouse isn't a big fan of 'frou-frou' food, as he likes to describe it. We do go to more reasonably priced (comparatively speaking) 1- and 2-star Michelin places, such as Aubergine/Carmel and Auberge du Soleil/Rutherford, and the unrated but excellent Michael Warring/Vallejo.
I buy chicken feet for the same reason I buy neck bones - both are essential for good stock making. You can't make great soup without good ingredients, and a great quality broth is not cheap to make, but worth it. There are no shortcuts to the traditional methods for best flavor.
My mother was an excellent cook. She once worked as housekeeper/cook to a family in a wealthy suburb near us, back in the 1980's. They adored her. She worked for them for 18 months before she got restless (she was an incredibly energetic person) and resigned. They said they were so sorry to see her go, she had NEVER repeated a single menu the entire time she worked for them.
Her employers gave her permission to have all of us visit for lunch one day when they were away traveling. She cured an side of entire salmon as gravlax and it was delicious. She had worked for a Scandinavian family during WWII in Minnesota (if you got a job, you were allowed to leave the internment camps) and was the only Japanese American I've encountered who had a taste for pickled herring in sour cream!
