I've been making this recipe for years...like at least 15 years! As a result, it has kind of "morphed" into something that I have memorized and just toss together, so giving you an actual recipe with actual amounts is a bit challenging, but I think for something like applesauce, that's ok. :)
Start by peeling, coring, and chopping apples. For this batch, I think we used about 8.
Place apples in a microwave safe bowl and cook on HIGH for 10-15 minutes until apples are VERY tender. (You may want to place a paper towel under the bowl as the liquid bubbles and sometimes overflows.) Stir every 5 minutes while cooking...being careful as the bowl and contents will get VERY hot.
The apples will cook down considerably.
Pour apples and liquid into blender (or food processor). Add water as needed for consistency, a splash of lemon juice (optional), a smidgen of sugar if needed, and cinnamon to your liking. :-) How's that for measuring?!? Blend until it reaches a consistency that you are pleased with. Some like it chunky, some like it smooth.... ;-)
Serve warm, or chilled. Or...just get a spoon and eat it straight out of the blender.
