Cookbook challenge, week 10: Rose-flavoured lassi with pistachios

This recipe comes from Tropical Asian Cooking: Exotic Flavours from Equatorial Asia. I think it's the first time I've used this book, although I've wanted to for a while. The recipes are interesting, fresh and have appealing photographs. Some contain ingredients that we can't get here (mostly fruit and vegetables), which only makes me want to cook them more!

The recipe I chose was rose-flavoured lassi with pistachios. I'm a big fan of the mango lassi, and so decided to try this flavour for something different. It's a fasciniating combination, and very refreshing.

Ingredients:
3 cups (750mL) plain yoghurt, chilled
3 tbs sugar
2 tsp rose water or a few drops of rose essence
6-8 ice cubes
2 tsp finely crushed pistachios

Blend yoghurt, sugar, rosewater and ice cubes until smooth
Transfer to 4 chilled glasses and sprinkle each with 1/2 tsp of pistachios
