Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Apple Roll or Apple Pudding
Ingredients
Directions
Peel and slice the tart apples.
Roll out the dough as thin as the bottom crust of a pie.
Spread the apples on the dough to cover it.
Dredge a little flour over the apples.
Roll the dough up tightly and cut the ends even.
Place it in a steamer or wrap it in thick cloth and boil for one hour.
Serve with butter and sugar sauce, cutting it into thin slices from the end.
