I Scream You Scream Part 1

Hello all!!! This is my first blog and I'm not really sure how this all works, but here goes nothin. Ice cream...love it. Homemade ice cream maker...like it. Ice cream that comes out of the homemade ice cream maker...ehh not so much. Don't get me wrong...I've made really delicious ice cream from my ice cream maker, but it doesn't always come out the consistency that i want it to. Everything looks great but once i start to scoop out the final product it always ends up being harder anticipated. Still very scoop-able, but its not the soft, fluffy, creamy confection that i was hoping for. But I think i found the solution...key word think. Recently I bought Jeni's Splendid Ice Creams at Home, and this book really schooled my on how to make homemade ice cream. I've been reading this book every night to understand the artistry of ice cream and today at work i decided to make ice cream on a whim. I decided to make the sweet potato ice cream with toasted marshmallows, and in typical Blackbeard style I "followed" the recipe. Meaning that I used the closest thing possible in place of the needed ingredient...60% of the time it works every time. Sweet potatoes were replaced with purple yam (which the books said was ok), molasses was replaced with just more brown sugar, and homemade vanilla bean marshmallows were replaced with store bought marshmallows. I did add vanilla bean to the ice cream batter. Everything was smooth sailing, until I took the milk and yam mixture out of the blender. It looked pasty instead of creamy, but i went on with it anyway, and the final product was again not the soft, fluffy, creamy ice cream i hoped for (but it still tasted pretty awesome). Womp womp. Maybe i should've added more milk or cream so it wouldn't have been so pasty...or maybe next time I'll just follow the directions LOL. Pic below.
