How To Make A Root Beer Float

I have always been a fan of dunking things – cookies in milk or shortbread in cold brew coffee. When I think of a root beer float, I have it in my mind that someone was taking dunking to the extreme and decided that ice cream should also be dunked in the nearest beverage which happened to be root beer. Nice, but not quite. It turns out that the guy who invented the root beer float just ran out of ice and used ice cream to cool his customer’s beverages. Now that is culinary innovation!

How To Make A Root Beer Float – The Ice Cream!

Regardless of the history, suspending ice cream in a rich root beer is nice on any day of the year, but, obviously, especially so in the dog days of summer. It is fun to state the obvious, but more fun to make a root beer float. When I make a root beer float, I very much like my ice cream homemade. A rich, custard style ice cream suits a root beer best because, as it melts, the liquid custard has the density to lend immense creaminess to a root beer. Big YUM!

Sure, a custard style ice cream might be more work due to the need for egg separating, but if you are careful, you can dispense with the whole double boiler. The eggs and sugar are creamed together until pale, then cold milk and cream are whisked in. It is typical to heat the milk first then temper the eggs. No need to do this. The mixture can simply be heated slowly with whisking until it coats the back of a spoon. This is made even easier if you use a thermometer. The custard base should read 175-180F. You will see it thicken. Just go slow so you don’t scramble the eggs! The custard base is then cooled and chilled and then churned in an ice cream churn.

How To Make A Root Beer Float – The Pour

The rest is easy – scoop ice cream in to a big glass, pour over the root beer. Pro-Tip: Never skimp on that ice cream when you make a root beer float. As for the root beer, it is one of those things that you have to search for to find the one you are most passionate about. There are many a root beer on the market. One must search to find the best for the float. Me, I like one of those mass produced root beers. I have no shame. It is the taste I grew up with. It takes me back! When I make a root beer float and watch that thick foam bubble to the top with the rich ice cream floating in the bubbly liquid, all I can think of is how refreshing it will be and how i drank it down as a kid.

  2. 1/2 cup sugar
  3. 2 teaspoon vanilla extract or 1 vanilla bean

  5. 1 cup of heavy cream
  6. 4 cans of root beer
  1. If using vanilla bean, split the vanilla bean and scrape the seeds out.
