What have you found to be the most widely used background flavors or additives in your mixes? Ya know, the ones you add to REALLY bring out a flavor, yet you can barely tell they are their (if even at all). I know the basic additives like EM, lemon juice, ACV, etc. What do you think the top 3 are??? And what about flavors?? I've noticed a lot of recipes that call for small amounts of strawberry, vanilla, or some variation of a cream product. What do you think are the top 3 "must haves" for any DIY'er??
