What luck, I just made a spinach souffle two nights ago!!
Had a bunch of fresh greens that were going to go bad if I didn't do something with them. Stuffed them into this blender and got it spinning. Started drizzling in milk and pulsing it, and once enough liquid was in there for it to take it drew everything right down in.
Souffle tasted great.
I just purchased the KSB560 version of this blender (same model with less expensive finish). I plugged in the blender new out of the box, and all the red lights came on and flashed. I couldn't get the motor to come on at all. I had to replace it and this one appears to work fine, but my initial experience (and stories from others having similar experiences) make we wonder whether this is one of those rare occasions where it would actually be worth buying an extended warranty.
you should ask the mfg. I always core my fruit, so do not know for sure. would guess yes, but take a bit longer. be sure to use pulse mode to breakup. for all veggies I use a juicer and then put that mix into the blender as ice cubes.
