If using fresh mangoes, peel and chop and puree until you have smooth mango puree.
In a bowl, add mango puree, melted butter and condensed milk. Mix.
To it add sugar and mix until evenly mixed.
In another bowl, add flour, baking powder and baking soda and mix.
Add this flour mix to the wet mix and stir until evenly mixed. Fold in the raisins. Add milk and mix.
Line a muffin pan with muffin cups and grease them with butter. Fill the muffin cups upto ½ full with the batter. I was able to get 10 muffins out of this batter.
Bake for about 20-25 minutes until a toothpick inserted in the center of muffin comes out clean.
Let them cool on a cooling rack.
Glaze:
Mix ⅓ cup powdered sugar with 2 tsp lime juice. If it is too thick add ½ - 1 tsp water and mix.
