Lake District, England — attributed to Francis Coulson and Brian Sack at Sharrow Bay Hotel, Ullswater, 1970s; also claimed by the Udny Arms Hotel in Scotland; the modern version was popularised by chef Nigel Haworth
Britain's most beloved modern dessert — a dense, moist sponge cake made with dates and brown sugar, served warm in pools of hot toffee sauce and usually accompanied by clotted cream or vanilla ice cream. The dates are not detectable as dates in the finished pudding — they are soaked in boiling water with bicarbonate of soda until they dissolve to a paste, providing extraordinary moistness and a deep, caramel sweetness without any identifiable fruit character. The toffee sauce (butter, brown sugar, double cream) is made separately and poured over the pudding both before baking (optional) and generously at service. Invented at the Sharrow Bay Hotel in the Lake District in the 1970s (disputed), the pudding became a British restaurant staple by the 1990s.
Dessert course at British restaurants and gastropubs; at home Sunday pudding; pairs with clotted cream, vanilla ice cream, or crème fraîche; the date-toffee-cream combination is specifically British in its unashamed richness
{"Dissolve the dates completely in boiling water with bicarbonate — the bicarb breaks down the date cell walls, producing a smooth paste rather than chunks; chunks of date in the finished pudding indicate insufficient processing","The bicarbonate serves a double function: it tenderises the dates and reacts with the date's acidity to produce CO2, contributing to the sponge's lift","Pour the toffee sauce over the sponge during the last 5 minutes of baking — the baked-in sauce produces a caramelised surface layer that adds depth the poured-at-service sauce alone cannot achieve","Serve hot — STP served at room temperature loses its defining quality; the warm sponge melting into the warm toffee sauce is the experience"}
Add 2 tablespoons of espresso to the toffee sauce — the coffee deepens the toffee's complexity without being identifiable as coffee; it is the same technique as adding coffee to chocolate cake to enhance depth. The pudding improves after 24 hours — make it the day before, refrigerate in the toffee sauce, and reheat in a 160°C oven for 15 minutes; the sauce continues to penetrate during refrigeration.
{"Visible date chunks in the batter — the dates must dissolve completely; a blender or food processor ensures complete incorporation","Cold toffee sauce — the sauce must be poured hot; cold sauce doesn't penetrate the warm sponge and sits as a separate, congealing puddle","Overbaking — a dry STP is a tragedy; the sponge should be just set in the centre and will continue to hydrate from the toffee sauce during service","Insufficient sauce — STP should be served in a generous pool of toffee sauce; a pudding with only a drizzle is a restaurant shortcoming"}
