Emerald Fennell’s lust-fuelled take on Emily Brontë’s novel has cued a hot flush of merchandise ranging from themed snacks to thongs. What exactly are they buying into?

T

hat appetite for Emerald Fennell’s bodice-ripping adaptation of Emily Brontë’s yarn of doomed romance is high is not in doubt. Whether it’s high enough to sustain sales for an official Wuthering Heights açai bowl seems less certain.

Yet this is exactly what is on offer in food aisles across the US, with two bespoke bowls churned up for hungry film fans with the explanatory slogan: “This is what happens when you turn yearning into flavour.”

“Cathy’s bowl is soft, indulgent, and impossible to forget,” promises the blurb for Kiss Me: “Strawberries are her wild sweetness, chia pudding is her composed side, honey is her sweet longing.” Haunt Me, meanwhile, is “dark, intense” like Healthcliff, and also “impossible to forget”. Thus: “Cacao nibs are his bitter soul, goji berries are his broken heart, choc hazelnut is his intense passion, blueberries are his cold restraint.”
