Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Rhubarb Tart
Ingredients
Directions
Prepare the filling
Skin the rhubarb stalks and cut them into 1-inch lengths.
Place the rhubarb in a saucepan with a few spoonfuls of water and stew until soft.
Sweeten the rhubarb while hot.
Assemble the tart
Stir in 2 teaspoons of butter and 1 beaten egg for each cup of fruit.
Pour the mixture into an open pie crust washed with egg white.
Optionally, bake with a top crust alone.
