Another good way to use a SMaSH, once you learn what that grain and hop does together, is to then start layering other elements into it for future batches. I built my APA this way, starting with all 2 row and Cascade hops and then adding some crystal and Summit in the next version. It can be very educational and helps when trying to learn what effect different ingredients have.
