Just ONE ingredient

Why is it that when you want to try a new recipe, it seems that you are always lacking just one ingredient?
I am a new subscriber to Cook’s Country magazine. I’ve been a part of the America’s Test Kitchen family for a long time, but I’ve used the cookbooks and the Cook’s Illustrated magazine.
So, my first issue arrived and I sat down to browse through it. YUMMY recipes, a lot of comfort food, not especially oriented toward someone on a diet, but great older recipes updated. There were several recipes I wanted to make immediately!
No….I need smoked paprika for the paprika potatoes. Hmmmm, no half-and-half for the cheese sauce for the broccoli. Darn! I need HOT Italian sausage for the “Quick Sunday Gravy,” Dutch-processed cocoa and milk chocolate chips for the chocolate pudding. Ooops…that’s two ingredients. Oh nevermind, it calls for heavy cream, too. I don’t think I have clam juice in the pantry to do the popcorn shrimp, and there are no Granny Smith apples for the apple fritters!
I’ve been told that if the local grocery store runs out of anything, they could call on me, but I can see that I’m falling down on my motto of “Be Prepared!” I don’t mind having to wait on most of this, but the potatoes and fritters are really talking to me! *G* Maybe it’s a good thing I don’t have all the ingredients.
