Trying To Re-Create A Classic Dessert Drink

In the town we live in there is an old-fashioned Drive Inn called The Rocket Drive Inn.  If you Google it, you'll get all sorts of hits with great reviews.  Lots of people coming off the Interstate probably hit up Sonic as we do from time to time, but if they would drive about a mile further, they'd arrive at the Rocket Drive Inn.  In my opinion it's better by a country mile!  We have posted about The Rocket before HERE.  People go to The Rocket Drive Inn for nostalgia, but it has really good food.  My favorite dessert to get there are their Root Beer Frosties.

I figured that I would try to re-create the Rocket Drive Inn Root Beer Frostie for dessert tonight at home.  If you look at the photo below you'll see what I'm guessing are the ingredients:  ice cream, root beer, crushed ice, homemade vanilla extract and... yep, we started milking Rosie again so we have fresh, creamy whole milk.

I tried the following ingredients:

• 1 1/2 cups whole milk
• 1 cup ice cream
• 1 cup crushed ice
• 12 oz. Root Beer
• 2 teaspoons vanilla extract

We blended for about 20 seconds in a blender and poured in a milk shake cup.

Although my photography skills are quite lacking and the photo above doesn't make our attempt at the Root Beer Frostie look appetizing, it was delicious!  However, one thing I need to work on to make it better is the proportions.  I felt like it wasn't as creamy or thick as The Rocket's Root Beer Frostie.  Their frostie is not as thick as a milk shake, but not as 'liquid-y' as a float.  It's somewhere right in the middle. Tomorrow night we will alter the proportions to add more crushed ice and more ice cream.  We will perfect it over time by trial and error.
