Why it works: Butter and flour 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 ↓
Petits Choux Aux Fraises
Ingredients
Directions
In a saucepan, combine cold water, salt, sugar, butter, and grated lemon. Bring to a boil.
Remove from heat and gradually stir in flour until a thick paste forms.
Return to heat, stirring briskly until smooth and it no longer sticks to the pan.
Let cool, then add eggs one at a time, stirring quickly until the mixture is firm and leaves the spoon clean.
Flour a surface, place the paste on it, and shape into walnut-sized pieces.
Butter a baking tin and place the pieces in it, painting them slightly.
