"Green mangoes are not fully ripe, and they lend sour flavor to Southeast Asian dishes. Their tartness contrasts with sweet carrot, refreshing mint and basil, and fiery peppers. Use an equal amount of unpeeled green apples if you can't find green mangoes." Cooking Light Magazine, June 2009 edition.Marinating time: 60 minutes - Waiting time: 10 minutes.
Update: 06/26/2009 - there was a computer glich when I wrote 1 large green (unripe) mango, peeled & shredded - it didn't take it at all and I was sure it was there but as one reviewer said, there wasn't anything posted about quantities etc of a green mango - I had to enter it in many different ways before it would take. I am truly sorry:(
