I used to be a yekke (3/4 yekke anyway) until I got married (My mother is yekke and my father’s mother is a yekke, although his father came from Poland, however he lost a lot of his minhagim after the war). My husband is regular litvish but his mother was sefardi from India. So we have some interesting food being cooked in my house now. My father davens in an Adass Yeshurun, my brothers are both married to girls from strong yekke families.
Just as an aside; when I went to Switzerland and they announced the landing time, the pilot said “we will be landing in approximately 5 to 8 minutes’ time”. Very specific for an approximate time.
