When we lived in Los Angeles, (moved there from Cleveland, Ohio) I missed:
Real Apples; Melrose, Cortland, Honeycrisp and other varieties we bought direct from the orchard.
Real Apple Cider with particles in it, no preservatives and non pasteurized.
Maple Sugar Candy
Tommy's Restaurant on Coventry, in Cleveland Hts, praised by Rachel Ray!
Grumm's Subs! I haven't had subs that good anywhere else.
Halevah. Ok, it's a Jewish thing, and for some reason, Jewish deli's in L.A. never heard of it. Bogframe! You got Halevah in New York?
It's a candy made from crushed sesame seeds and honey. It is firm, yet soft. Some kinds have nuts in it, some rippled with chocolate.
Russian Tea Biscuits - this is ruggele on steroids, about the size of your fist. Can't get them anywhere but Cleveland.
Now that we are back in Cleveland, the only food I miss from L.A. is:
Numero Uno pizza.
Every other kind of food I can think of we have, because we have such a huge ethnic mix here. We have pizza here, too, but not like Numero Uno. the crust has to be 1/2" thick! Mmmmmmm!
