I love the garlicky roast crab and garlic noodles found at a couple of Euro/Vietnamese restaurants in SF. I have tried, to no avail, to recreate the "secret" sauce. I've tried combining garlic, butter, anchovies, sesame oil, nuoc nam, and parmesan cheese (for the noodles only), at home, but the flavor still eludes me. Has anyone had better luck at this? Would love to hear about other possible combos.
