The purple cauliflower did not change colour during cooking. I teamed it with its white cousin - which it turned lilac! I'm amazed to say everyone ate it quite happily and Minx declared it better than normal cauliflower - DH has just said the photo looks like entrails - nice ;p
Purple cheese sauce is a sight to behold LOL. I feel maybe this vegetable would be better served as a side veg without the sauce!
and if you thought that was bad just look at the colour it turned the water in the bottom of the steamer!!!
Yup, it really is deep turquoise. Bon apetit!
