Oh, it's *almost* warm enough to be thinking that way... going to go to the plant sale and put some maters in this weekend. Just stick the stuff in the blender and whale away? (The weird thing will be not watching the stuff blend... no, I can just adjust my mirror!)
I found this online that looks really, really tempting... and I'm thinking of all those invitational rides where they have three boxes of battered bananas at the end...

1 banana
1 tablespoon chocolate syrup
1 medium cup of milk
1 medium cup of crushed ice
Method Chop the banana into four pieces then add to the blender. Then add the chocolate syrup, milk and crushed ice. Blend until smooth. Pour into glasses and serve.
