I've made them using this recipe. It's pretty spot-onYou can start by buying them from Costco. No shit, for at least a while (maybe still do? Haven't looked) they sold an officially-branded Red Lobster kit to make them. All the dry stuff, no cheese either (for obvious reasons), and the procedure is there.
So make that, then de-construct it. You'll be pretty close.
