The leaves of the may aren't fully out here yet never mind the blossoms.
This "clout" word - originates from Anglo-Saxon, pronounced "cloot" (and still is in Scotland), so the rhyme goes -
"Ne'er cast a cloot
'Til may be oot"
A clout is a generic term for a piece of cloth, which may refer to a garment.
Aaaanyway, my auld grannie used to make "Clootie pudding" which necessitated a mix of dough and dried fruit wrapped in a piece of cloth and boiled for a fortnight in the very same cauldron as like wot I use to this very day.
Delicious - and the next morning the remainder of said pudding was fried up in bacon fat for breakfast.
