Harrison, perhaps that average unmarried guy ought to think about finding a girlfriend who can cook (and put up with the idea that she will never be able to stand up to the memory of his mother) ... or .. if he is a millennial who wants 'control', he could learn to cook himself! 
But, seriously, you keep coming back to the idea that someone has nostalgia for something that they ate in the past, something that reminds them of 'home', which was most likely cooked by a relative or friend, now gone or too far away to be able to share their cooking with the person who is reminiscing about it. On the other hand, the eGullet crowd most likely would be more inclined to want to order some exotic dish from a far away land we have never managed to visit or have never seen otherwise available locally to try. I think you need to define your target market much more clearly (which is basic entrepreneurship 101 stuff). You just cannot be all things to all people.
(p.s. for a perfect illustration of the issues many of us have tried to talk about - that of the variability of recipes which all go by the same name - take a look at the thread IndyRob has going about Cacio e pepe.)
