What to do with that cup of onion juice? Use it to steam up a bag of baby carrots with salt & pepper, then stick the immersion blender in there and whiz them up with buttermilk. Mix in snipped dill, serve cold. Yum yum. Low fat, low maintenance, highly tasty. It would probably even go nicely as a first course with the kebab kubideh, though if you haven’t so generated onion juice you could probably just steam some onion in with the carrots.
