Why it works: Truffle and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,900 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Trout Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the trout
Wash and clean the trout, removing the fins and head.
Lard the meat with anchovies and truffles, then season with fine spices and coarse sea salt.
Stuff the trout with good butter or chopped lard mixed with chopped truffles and fine herbs.
Assemble and bake
Arrange the trout on the pastry with optional artichokes and mushrooms.
Cover with hash and slices of fat meat or butter.
Finish the pie and bake for 2 hours at 350°F (175°C).
