Mango panna cotta (if you can call it that)

[This was adapted from Mona's coffee panna cotta recipe, and has been made twice more after that. Not sure what it is called, but it works for me and my family.]

1/2 cup milk
1 1/2 teaspoons unflavored powdered gelatin
1/2 cup cream
1 cup mango pulp
3 tbsp sugar

Place the milk in a heavy, small saucepan. Sprinkle the gelatin over and let stand for 5 minutes to soften the gelatin. Stir over medium heat just until the gelatin dissolves, but the milk does not boil (about 2 minutes).
Add the cream, the mango pulp, and the sugar. Stir over low heat, until the sugar dissolves (about 3 more minutes). Remove from the heat and let cool slightly. Pour the mixture into a mould, cover and refrigerate, stirring every 20 minutes during the first hour. Chill until set, at least 6 hours and up to 2 days.
