Green smoothies: An Apology

I have to make a public apology to regular commenter Elizabeth. When we were having this discussion back in May about sneaking healthy things into your family's food, she emailed me to say that she's started putting a little frozen spinach into fruit smoothies. She claimed that you couldn't taste the spinach at all. I attempted to be polite, but just couldn't imagine how you wouldn't taste spinach in a fruit smoothie.

I was wrong. Elizabeth is right. You can put spinach (and I'm assuming other greens) into a fruit smoothie and you won't taste them.

I'm thrilled about this discovery, because my kids are great about eating red and yellow and orange vegetables, but leafy greens are a crapshoot. El Chico will eat any kind of greens slathered in ranch dressing, but it's mostly about the dressing, and I'd rather have him just eating the greens.

In the past week I've made the following smoothies that went over like gangbusters with my husband and my toddler (El Chico wasn't willing to drink anything green, and drank some of the last one but stalled out to play with his matchbox cars):

#1
Half a bag of baby spinach
A big handful of frozen mango chunks
Half a can of coconut milk
A splash of water to get the blender started.

#2
Half a bag of baby spinach
A big handful of frozen mango chunks
Half a banana
Enough unsweetened cranberry juice (thinned with water, because unsweetened cranberry is too strong) to make it blend.

#3
Half a bag of baby spinach
A big handful of frozen raspberries
A banana
Enough water to get the blender started.

#4
Half a bag of baby spinach
1/5 to 1/4 of a pint of Stonyfield Farms After Dark Chocolate frozen yogurt (the richest chocolate frozen yogurt I've ever had)
A banana
Enough milk to make the blender run.

I hid spinach in a chocolate banana milkshake. Bwahahahahaha. I am drunk with power.

You can't taste the spinach. Am I the last one to know this? What should I try next? Parsley?
