Why it works: Flour and lemon are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 30,404 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rough Puff Pastry
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Mix the dry ingredients in a bowl.
Cut the shortening into 4 pieces and add to the flour.
Make a well in the center of the flour.
Add lemon juice to the cold water and mix until elastic.
Turn the mixture onto a floured board and work it a little.
Laminate and bake
Roll out into a long strip, flour lightly, fold in three, and roll out again.
Repeat the flouring and folding process, rolling out a third time, and a fourth if necessary.
Use for sweet and savory dishes, and bake in a hot oven at 400°F (200°C).

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Flour
- Forms the structure of the dough that holds the layers together.
- Shortening
- Creates separate fat layers that steam apart in the oven, producing flakiness.
- Cold water
- Hydrates the flour to develop gluten, giving the dough its elasticity.
The step that matters
Keeping the shortening cold and in distinct pieces. If the fat softens or blends fully into the flour, it will not form separate layers. Steam released from the water in the fat then cannot lift the dough, and the pastry turns out dense instead of flaky.
