😁 A wee chuckle from Oxford Ref:

LIBERTY CABBAGE

During WWI any reference in the USA to things German was deemed unpatriotic, & this included foodstuffs. An alternative name had therefore to be found for sauerkraut, and the choice fell on liberty cabbage. The image appealed to was presumably of America as the land of the free, defending the liberty of the world against German tyranny. Similar inspirations were liberty sandwich for ‘hamburger sandwich’ [&] liberty measles for ‘German measles’.
