Durian Muffin

I have been wanting to bake durian muffins for such a long time. Today,I finally managed to find some time to get the main ingredient for my muffins...DURIAN!
The durian season seems to be around already, I bought durians in ready-packed form, 3 packets for $10. They were D24 type of durian, not bad also, the flesh were in bright yellow and tasted very sweet.
Durian muffin recipe:
Ingredients:
300g all-purpose flour
100g sugar
2 teaspoons double baking powder
1/2 teaspoon salt
75g butter, melted
1 egg, lightly beaten
3/4 cup milk
500g durian pulp
Method:
1.Preheat oven to 190 degC.
2.Melt butter over low heat in a saucepan. Set aside.
3.Separate durian pulp from seeds, mash slightly with a fork and set aside.
4.Add egg to the melted butter. Stir till combine. Add in milk and half of the durian pulp. Stir to combine.
5.In another bowl, combine the flour, sugar, double baking powder and salt. Use a spatula or whisk to mix the dry ingredients completely .
6.Add the wet ingredients to the dry ingredients and stir only until the ingredients are just combined. The mixture will appear very lumpy. Do not over mix the batter otherwise the muffins will become tough.
7.Spoon batter into the muffin cups, filling half full. Add 1 teaspoon of durian pulp to each, top with remaining batter. Fill up with the remaining batter to about two thirds full.
8.Bake for 25 to 30 minutes or until a tester inserted in the center of a muffin comes out clean.
