Getting ready to drop the question, any advice?

So I was at a loss on how to propose after I got the ring sorted out. My plan is very simple I guess. I am cooking a fancy meal, white table cloth, candles, Wine etc. She knows I am cooking but she dosen't know I am going crazy with it. Her sister will keep her out of the house while I get ready with some christmas shopping. I have a desert tray that I will put the ring on surrounded by flowers. So when I bring the "special" desert out and lift off the cover I will surprise her with the ring.

So is it lame that I'm asking her in our kitchen? Any advice or suggestions....
