Well, based on recent DNA testing and hundreds of hours of genealogical research, I found out that I am way more a mongrel than I ever knew possible. My heritage is exactly thus:
Ethnicity % Surnames in Our Family
Danish 31 Nielsen, Zink
German 23 Domann, Wegner, Kremers
English 15 Taylor
Irish 8 Dehart, McDaniel, McFarrell
Polish 6 Klug, Polzin
Swedish 6 Moline
Norse 6 Alme
Dutch 3 Koch
Jewish 1.5 Gould
French <1 Monsieur
I have always enjoyed breakfast danishes and kringles, but then my family always knew we were Danish so that wasn't blind. Later in life I got to appreciating German beers and sauerkraut a lot more, but again, I always knew I was German. What I never knew is that I am Polish, Swedish, Norse, Dutch, Jewish, and French. Hmm..... I like Polish kielbasa and Baltic porter. Was that my roots calling back to me? I think not. I think those are just delicious foods. I always loved Dutch-processed cocoa and never knew I'm Dutch. My ancestors calling to me from beyond the grave? No, I don't think so. Yadda yadda...... I use the term "yadda yadda". Is that any reflection on my Jewish ancestry? Heh.
I enjoy talk of this stuff, but do be careful about assuming "I am this" or "I am that". I was unaware of half my European heritage until I spent many many hundreds of hours looking up all the family history up every single string back like 7 or 8 generations if not more. If we are all mongrels, then...... well.....
Bottom line is that instinct or genetics isn't dictating what we naturally love or hate IMO. I think it's way more personal preference and upbringing than genetic heritage.
Cheers to you this lovely Sunday morning.
