Pour some sesame oil into the pot. When the oil is hot, pour in the fried walnuts. Stir-fry until golden brown. You can taste it to see if it's crisp enough. Then take it out and filter out the oil. You can put it on the paper tower. Because the walnuts were fried for more than a catty, they were divided many times before frying. Choose the smallest fire and turn it with chopsticks while frying, so that the sugar won't burn.
You can eat it when it is cold, and it will be more brittle when it is cold. You can sprinkle a little salt to taste better.
