Seared Scallops with Cauliflower Puree

I know, sound fancy enough for you? I love seafood and am always up for trying something new, so when I found this recipe, I figured, "Why not?"

Seared Scallops with Cauliflower Puree
2 c chopped cauliflower florets
1 c cubed, peeled Yukon gold potato
1 c water
1/2 c chicken broth 
1 T oil
1 1/2 lbs sea scallops
3/4 t salt
1/2 t black pepper
1 1/2 T butter

Bring first 4 ingredients to a boil in a saucepan. Cover, reduce heat and simmer until potato is tender. Remove from heat and let stand, uncovered, for 10 minutes.
Heat a large skillet over high heat. Add oil, swirl to coat. Sprinkle scallops with 1/4 t salt and pepper and add to pan. Cook 2-3 minutes on each side or until done. Remove scallops from pan.
Pour cauliflower mixture in a blender and add 1/2 t salt and butter. Secure lid (but keep the center open to allow steam to escape) and blend until smooth.
Serve together.

NOTES
I used mini scallops as that was all I could find, but the big ones would have been a LOT better.
