Carmelized crust? Oh, yummy, yum! That sounds extra special good! I will definitely check it out then, or some variation on the theme.
So, since we’re talking spices, have you heard of togarashi? It’s a standard Japanese blend I pick up in a unbelievably cheap bottle at Uwajimaya. It has some heat and is awesome as a rub on tuna or halibut before the grill smokes it up. I’ll list the ingredients of the House Spice brand I have cuz I’m hungry :), but there is probably variability across brands: red pepper, roasted orange peel, yellow sesame seed, black sesame seed, japanese pepper, sea weed, ginger.
Now, I’m starving. ;).
