June Taylor Jams--esp. her marmalades w/ more unique citrus that you won't find in more commercial products--like blood orange or meyer lemon.
You can get them @ the Ferry Plaza Farmer's Market or the list of retail stores below:
She also ships gift packages directly--I did that for foodie cousins in Tennesse--a variety of jams, marmalades, and syrups--and it arrived nicely packed and was a big hit.
Darn this globalization thing! 15 years ago I could surprise family and friends living in colder climes with treats they otherwise could not find. Now you can find almost anything anywhere.
I like to send Scharffenberger Cacao "Nibs," which I munch on, use for cooking, ice cream topping, and have even used them in making homebrew. And I do not know where else to find them outside of the bay area (not that I've looked). I buy them at Monterey Market
Maybe something made with persimmon?
La Cocina sells gift boxes. Everything made in SF.
Alternately, you could visit their kiosk in the Ferry Bldg and pick and choose.
Bonus: It's right across from Mariposa bakery kiosk which is gluten-free.
