Spinach Souffle Surprise

Today I learn to make a souffle.

A spinach souffle (what's not to love about spinach and eggs w/cheese?!)

Requiring a souffle dish, I sourced a basic one (Portuguese, not French) at Ross, of all places!

(we often find great values on ceramics at TJMaxx as well; I found Polish terra cotta yesterday!)

My first inspiration came from a beautiful image with the Barefoot Contessa's recipe.

I can't find it so I'll give you this instead; a cute lil' pic of a souffle for one from RaspberryEggplant~

For good measure, I sourced a few more recipes to compare; The Spinach Souffle Surprise version at IndianFoodForever.com was deceptively simple so I'm wondering what the 'surprise' could be...
