Flummery

Flummery is a starch-based, sweet, soft dessert pudding which originated in Great Britain during the early modern period. The word has also been used for other semi-set desserts. The name is first known in Gervase Markham's 1623 Countrey Contentments, or English Huswife vi. 222 "From this small Oat-meale, by oft steeping it in water and clensing it, and then boyling it to a thicke and stiffe jelly, is made that excellent dish of meat which is so esteemed in the West parts of this Kingdome, which they call Wash-brew, and in Chesheire and Lankasheire they call it Flamerie or Flumerie". The name is derived from the Welsh word for a similar dish made from sour oatmeal and husks, llymru, which is of unknown origin. It is also attested in variant forms such as thlummery or flamery in 17th and 18th century English. The word "flummery" later came to have generally pejorative connotations of a bland, empty, and unsatisfying food. From this use, "flummery" developed the meaning of empty compliments, unsubstantial talk or writing, and nonsense.
