Apple- banana milkshake

This is from the list of my little experiments. I used Ricotta cheese instead of ice-cream as I had it in my refrigerator.
My grade: good
Preparation time: 10 min.
Ingredients:
Apples :2
Apples can also be substituted with strawberries.Then it becomes strawberry- banana milkshake of course.
Ripe banana:1
Ricotta cheese or any ice cream: 2-3 tbsp
Sugar to taste
Milk : 3 -4 tbsp
Method:
Grind apples into a smooth paste first.
Then add rest of the ingredients and grind well.
If you want to dilute the drink, then add some more milk.
Refrigerate before serving.
