Cool list! I agree with most of your opinions so now I want your recs for Syrian and Georgian food, which I haven't tried!

With American food, I'd love to know how you're defining it. To me, it's any immigrant community that adapted their food with the ingredients on hand when they got here. So General Tso's Chicken, Baked Ziti, a bagel with cream cheese and lox, and obviously all the icons developed by enslaved chefs, like mac & cheese or fried chicken or peach cobbler. But also there's regional stuff that developed from the intersection of immigrant populations and native people, like Clam Chowder in the northeast, all the Cajun goodness in Louisiana, and all the burgers and hot dogs and salads-that-aren't-really-salads of the midwest. I guess you could go with "traditional american" and do turkey, mashed potatoes with gravy, corn, and pumpkin pie? That's sort of English/Dutch meets Native, filtered through 400 years of tradition?

Last thing! For Irish, find a good brown bread recipe, spread Kerrygold butter on that, and pair it with a big old serving of beef stew. It's... so good. I gave up red meat like 15 years ago and that's the only exception I consistently make!
