Just suck it down, drink it all up. Yum.
Or, if you want to share...
Mango sorbet or icecream is delicious. Just google for plenty of recipes.
It's also lovely over vanilla icecream, or a macadamia icecream is wonderful with mango.
Mix with mint, lime and soda water for a refreshing drink. Add vodka if you like.
I'm not sure how it would work with puree (it should be fine), but I've often made a salsa with finely chopped mango, mint, cucumber, lemon, macadamia, chilli, and coriander. This is lovely with grilled fish or chicken.
How about mango chutney? Again, it's usually got chopped mango, but puree should be fine.
Or you could just drink it!
