Here's the recipe that I've got for Mango Lassi.
Ingredients9 fl oz plain yogurt
7 oz mangoes, peeled and chopped into pieces
3 1/2 oz mango pulp
1/2 cup (4 fl oz) milk
4 teaspoons white sugar
4 crushed cardamom pods Method Put all of the ingredients into a food processor
Process into a thick, smooth, paste (about 2 minutes)
Put into a bowl, cover with kitchen film, and cool in the fridge for 2 hours
Serve in a tall glass
I've been experimenting with the recipe to try and make it better. The lassi is too sweet so I've dropped the sugar - the mango and mango pulp are sweet enough by themselves. And the cardamom pod husks don't always get blended up correctly so I just use the seeds from the pods instead.
As far as I'm aware, yogurt is yogurt.
I'll try your idea and increase the milk content. It should water it down a little. I'll let you know the results.
Thanks for the idea.
