Why it works: Walnut and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,149 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Walnuts in Brandy
Ingredients
Directions
Choose unripe walnuts and peel them carefully, placing them in cold water as you peel.
Bring water to a boil and add the walnuts, removing from heat as it begins to boil again.
Drain the walnuts and place them in cold water with a little lemon juice.
Boil cane sugar until it reaches a small thread stage, then drain the walnuts and pour the sugar over them.
Let the walnuts sit in the sugar overnight.
The next day, strain the sugar and boil it again until it forms a longer thread.
Let the walnuts sit in the sugar for another night.
Repeat the boiling and soaking process one more time, allowing the walnuts to sit for a fourth night.
