Well...hmm...
I spend my childhood in different countries and locations in USA.
From my mom I will say
1- noodle meat soup made from scratch. Really good in reality and have not one as good so far in the market or restaurants. Not eaten since kid.
2- Funche with cod or red beans. Funche is corn starch make it like making regular rice. It can be eaten with milk or beans and others. I do not try that with milk since kid time.
3- Balaju fish just caught in the early morning first capture and going to the market at 5 am and get it for dinner. Not eaten since then.
4- Bacalao con verengena. That is cod with egg plant in tomato sauce with nice others stuff to give nice flavor. Not eaten since kid.
5- Bread from Don PEPER BAKER. so good. Sad when the building got fire. USA New Mexico
6- At the roadside there was a guy making Chicken BBQ, but the cow large ribs BBQ was amazing, and no other BBQ has tasted like that one so far. Back in the Caribbean.
7- Salmorejo de jueyes. it is a kind of crab soup. Mis that and the special hot sauce for the plantain never taste a hot sauce better so far.
8- Ramen bar places back in Japan when I was in Japan.
9- Back in Panama there was a lot of similarities in food with Puerto Rico with differences but been apart was very curious like sancocho , corn tortillas, carimanolas, ron ponche, pargo frito and few others. Never eaten since then.
There are many others, but I can talk later about them.
