ChoppedWalnuts
According to http://www.joyofbaking.com/walnuts.html :
1 cup halves = 100 grams
1 cup coarsely chopped = 110 grams
If the grocery store at Zhongshan Park sells walnut halves for RMB 31 each 500 grams, then the 2/3 cup of finely chopped walnuts I need to make a batch of nut cookies should cost how much? A generous estimation:
2/3 cups finely chopped = 1.5 cups halves
1.5 cups halves = 150 grams
150 grams * RMB 31 / 500 grams = 9.3 RMB
Or about USD 1.13
