Final answer:
The choice of ice cream flavor depends on personal preference and desired flavor combinations.
Step-by-step explanation:
If a blizzard has cocoa fudge, the ice cream flavor that should be on the bottom depends on personal preference. However, you can consider a few factors to make a decision. For example, if the cocoa fudge is rich and has a strong flavor, vanilla ice cream can complement it well by providing a neutral base. If the cocoa fudge is more intense and bittersweet, chocolate ice cream can enhance its flavor. Ultimately, the choice of ice cream flavor depends on the individual's taste preferences and desired flavor combinations.
