At 47, Rani “Raz” Razvan has spent five years fermenting cucumbers and grief in her late mother's shuttered Peckham shop—a corner of London where her grandmother once turned wartime scraps into survival. Now, facing crushing debt and a buyout offer from a trendy café chain, Raz must choose: sell the crumbling legacy or honor three generations of women who transformed sourness into sustenance. When her estranged daughter returns after a public failure, their uneasy alliance sparks an unexpected community project—teaching preservation to refugees, asylum seekers, and invisible neighbors. But can mason jars and memory hold back gentrification? In a neighborhood erasing its immigrant roots, Raz discovers that some traditions must evolve to survive—and that the quiet work of women's hands might be the most radical resistance of all.
