Where can I find these in Los Angeles or the San Fernando Valley? Thanks
They have them at the Silverlake Cheese Store. Oh, and also at the World Market.
There is also a short cut recipe you can make at home. [Google]
Check out http://sqirlla.com/ (hours are limited, but some stuff is also sold at Proof Bakery in Atwater). Her preserved Meyer lemons are delicious (though if you're looking for a very traditional Moroccan recipe, Eurekas may be a little more traditional).
They're also easy to make at home, though you do have to be willing to wait a few weeks to use them.
