What does clabbering mean?
Clabbering refers to the natural process by which raw milk sours and thickens into soft curds, a phenomenon familiar to farm households before refrigeration made such spontaneous fermentation a kitchen staple rather than a mishap. The word functions as the present participle of the verb 'clabber,' and in regional American usage — particularly across the Southern and South Midland United States — it can also serve as a noun denoting the curdled milk itself, though the simpler form 'clabber' is more common in that role. Clabbering carries a distinctly rural, old-fashioned connotation, evoking buttermilk biscuits, churned butter, and self-sufficient kitchens where soured milk was an ingredient to be prized rather than discarded. Outside these regions and contexts the word is rare, and listeners may mistake it for 'blabbering.' It remains a flavorful piece of American culinary vocabulary, useful both literally and as an evocative marker of heritage cooking.
Thickening or curdling, especially said of raw milk turning sour and forming soft curds.
"The cream was clabbering in the churn by midmorning."
Almost always applied to milk or dairy; figurative use is rare.
The act or result of curdling; curdled, soured milk.
"A bowl of clabbering sat on the table alongside the cornbread."
In this sense the uninflected form 'clabber' is more common than 'clabbering'.
Before refrigeration reached the American South, clabbering wasn't spoilage — it was how you made breakfast.

Etymology of clabbering
Clabbering derives from 'clabber,' which entered English in the early seventeenth century, likely via Irish Gaelic 'clabar,' meaning mud or thickened milk. The related term 'bonnyclabber,' from Irish 'bainne clabair' ('thick-milk'), preserves the fuller original phrase and was common in colonial American English. The word took firm root in the speech of the American South, where clabbered milk remained a dietary staple long after it faded elsewhere.
