We've got dates and, as usual, I've got frozen bananas. They're a fine combination, and I've been choosing to combine them in smoothies. They're both plenty sweet as they are, so all they really need is some milk. I also like the teensiest pinch of ground cardamom.
Whenever I get to the smooth dates and banana stage I notice that this would probably make another fine banana icecream. My processor can't quite blend the dates to smoothness, so the 'icecream' is flecked with their caramel sweetness. They're a treat when I find them sunk into the last quarter of my smoothie, too.
Remove the pits from 6-8 dates and place them in a food processor. Process the dates until they're as mushy as they're gonna get (mine are usually still quite chunky when they're out of the blade's reach). Add a couple tablespoonfuls of milk (dairy or non-) before processing some more. Add a frozen banana and a pinch (just a pinch!) of ground cardamom and process it all until smooth. Then with the motor still running, gradually add more milk in a stream to get the quantity and consistency you want. Pour it into a glass and drink up!
