I would definitely not just try to find a different recipe or stray far from the original. Your friend has certain memories and expectations of what this cake is. It would be sad to disappoint him.
Thanks! You are absolutely right about sticking close to the recipe. And using the Spectrum shortening is a great tip.

added about 1 year agoI also agree about changing the margarine to butter. Those old recipes come from a time when margarine was believed to be a healthy and tasty alternative to butter. My mother has tons of them, and she's always surprised at how much better everything tastes when you use butter instead.
