Why it works: Walnut and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 5,873 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Hungarian Apple Pie
Ingredients
Directions
In a teacup, mix hot water with the piece of lard until melted.
Cool the mixture by adding cold water, then add the egg and mix thoroughly.
On a clean surface, place the flour and stir in the water and egg mixture until fully combined.
Knead the dough until it no longer sticks to the surface.
Pound the dough by throwing it onto the board repeatedly for 10-15 minutes until it is full of air bubbles.
Cover the dough with a heated bowl and let it rise for 30 minutes.
Sprinkle flour on a large table and place the dough in the center.
Roll out the dough with a rolling pin until it is larger than a dinner plate.
Gently pull the edges of the dough to stretch it thinner than paper, allowing it to hang over the sides of the table.
