The season is relatively short for McIntosh apples - though I've seen some in stores lasting through February and March (but those are the ones that have been in cold storage) Get 'em while they're at their peak -- and make this applesauce!
Into a medium saucepan, add the apples, brown sugar, lime juice and water. Cover the pot tightly and heat to boiling.
Reduce heat to a simmer and cook for 5-8 minutes, until apples are tender.
Transfer to a blender or food processor and pulse 3-4 times to desired consistency. If you like it chunky, process it less -- or for uber-smooth -- pulse a few more times.
