Tips:Peanuts and walnut dregs should be fried in advance before using. The coarse granulated sugar I used was not completely melted when baking, and it tasted better, crunchy. If you don't have one, you can use regular sugar. The baking time and heat must be in place, so that it will be crispy and fragrant after being baked.
