Thanks everyone, it went great. I'll post a pic later of my niece with her Peches Cardinale,
which was her main motivation.
She and I worked in the kitchen while Jacques and her parents had wine and cheese at the counter. Her brothers were engaged elsewhere so thankfully there are leftovers.
I'm glad I kept the rest of the meal really simple. She couldn't believe how easy the Spicy Garlic Shrimp are, and plans to do them in the dorm kitchen. We did three vegetables--braised carrots, blanched green beans and sauteed zucchini.
We did the rice almost exactly as Pat suggested, without reading the suggestion. We followed Julia's Riz Duxelles, but used sliced mushrooms instead of minced, which gave me a chance to show how to saute mushrooms.
Rick's post on the easy sauteed chicken breast was just perfect, and the mustard cream sauce was excellent. I will add wine next time just to see, but it was delicious as is.
I think I now have the makings of a confidence-building "Cooking 101" type class, with the shrimp, chicken, mushroom rice, two of the vegetables and perhaps a simpler dessert.
Thanks again!
