Final answer:
Blue Bell's top flavor is often referenced as Homemade Vanilla. The specific details regarding the year it was created and the creator are not widely known. The second-best flavor is also not definitively known due to changing preferences and limited sales data.
Step-by-step explanation:
Blue Bell Creameries is well known for its wide range of ice cream flavors. As of the knowledge cutoff in 2023, the information regarding their top flavors might vary depending on the source. However, traditionally, Homemade Vanilla has been known as one of Blue Bell's top-selling ice cream flavors. Unfortunately, the exact year this flavor was introduced and the individual who created it are details that may not be widely reported and could potentially require specific historical data from the company. Likewise, identification of what is considered Blue Bell's number 2 flavor can be equally challenging due to varying tastes and preferences and potential changes in sales figures over time. Blue Bell produces a variety of flavors, making it difficult to pinpoint a consistent second-best without current sales data.
