I LOVE my (semi)local Japanese grocer! H-Mart is INCREDIBLE. They have an incredible selection. Some recent takes:
-Satsumaimo sweet potatoes (my favorite)
-Okinawan sweet potatoes (white flesh/purple insides)
-Rice paper for spring rolls (tapioca flour + rice starch + water + salt, that's it!)
-Wild white shrimp - always $4.99/lb fresh, not frozen
They have fresh pork belly, whole pig hearts, monstrous bags of chicken drumsticks for $0.79/lb, ox tongue...there's some freaky stuff in the meat department. I love that place.
They're one of the only places I can find legitimate "yams" that aren't just mis-labeled sweet potatoes. They have some weird African tubers there that I've never seen before. Many are boobytrapped with strange spikes and thick, bark-like skins. One day I will experiment.
Don't put your trust in anyone on this forum, including me. You are the key to your own success.
