Prepare apples & put the apples and water into a large microwave-safe bowl  (I use my biggest yellow Pyrex mixing bowl).

Cook, covered, on HI 10-12 minutes.

Let sit in microwave for 3 minutes.

Stir well with whisk. It may need to cook another minute or two, depending on what kind of apples you used.

Stir in sugar.

Store in refrigerator.
