Why it works: Rhubarb and cream work together. They rank in the top 10% of all ingredient pairs, and 297 recipes mention both. Both carry acetic acid, which smells sour, vinegar. The science ↓
The recipe
Serves 4Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the oven to 375°F (190°C). Grease a 9-inch (23 cm) baking dish with the knob of unsalted butter.
Cut the rhubarb into 1-inch (2.5 cm) pieces. Toss with the 2 tbsp golden caster sugar, the juice of the half lemon and a little of its zest. Spread in the dish.
Cut the cold butter into cubes. Rub it into the flour, salt and 200g golden caster sugar with your fingertips until the mixture looks like coarse breadcrumbs.
Scatter the crumble topping evenly over the rhubarb without pressing it down.
Bake for about 50 minutes, until the topping is deep golden and the rhubarb is bubbling and tender when pierced with a knife.
Rest for 10 minutes so the juices thicken slightly. Serve warm with chilled Guernsey cream.
