I need to make a quick dinner tonight (say, no longer than 45 minutes) and would really prefer not stopping by the store, so I have to cook with what I have. I was thinking doing rice and shrimp with a sauce, but I'm struggling with the sauce. I'd prefer something creamy, but of course, I don't have any milk. I do have flour, butter, white wine, your various wine vinegars, olive oil and about 4 cups of chicken stock. Any ideas? I've also got onions, lots of condiments to give flavorings (I always love spicy!) and garlic.
