Root beer and Coke floats aren't the only soda-and-ice-cream combo beloved by Texans.

This week, Whataburger launched a limited edition Dr Pepper shake, a twist on the old-fashioned soda fountain treats of yesteryear, but not everybody is convinced that Dr Pepper blended with vanilla ice cream is a good idea.  In my weekly livestream on Wednesday on the Austin360 Facebook page, the Statesman's newest staffer Johanna Gretschel — and Dr Pepper shake doubter — joined me to try the shake and a handful of other new and not-so-new products.

At first glance, Whataburger's latest dessert creation looked like a chocolate shake, but the smell of Dr Pepper greeted you before the straw hit the slurry. The richness of the soda paired well with the vanilla in the ice cream, making what might be an idea soda shake. Gretschel didn't not like the shake as much as she thought she would, but she still wasn't convinced. Everybody else in the newsroom, however, thought those big flavors in the Dr Pepper shake were the best thing since Whataburger's spicy strawberry jam.

We also tried the new Greenbelt Kombucha, a local canned kombucha that is made with a variety of teas, including rooibos, white and yerba mate. The kombucha has less sugar and lactic acid than traditional kombuchas on the market, and the result was a fizzy, easy-to-sip, lightly flavored drink that was more akin to La Croix than a traditional soda. You couldn't exactly taste the different teas used to make the drinks, but the flavors were balanced and refreshing. Also, the makers don't use stevia, which allowed the dried fruit they use to add flavor the drinks to come through.

Another new product on our livestream came from the San Antonio restaurant Orderup, which has been selling these big buttery chocolate chip cookies for almost 15 years. The company recently decided to start a mail-order division, CH2 Cookies, so they could sell these cookies in packs of 6 and 12 ($18 and $28, respectively, including shipping). The dome-shaped cookies are dense with chocolate, but they also have a slight cookie dough texture on the inside without being gooey. In addition to the classic flavor, the company also sells a gluten-free cookie for a few extra dollars per box.

You can't eat chocolate chip cookies without a glass of milk, but instead of regular milk, Gretschel and I tried Oatly, the hugely popular oat beverage from a Swedish company that has been around for nearly 30 years. The brand has become so well-known among consumers who don't drink traditional dairy that the drink has been hard to find in grocery stores. Whole Foods recently started carrying a larger supply of Oatly, so I was able to buy a half gallon for the livestream. The drink is more milk-like than many soy, almond and rice beverages, and it has the soluble fiber typically found in oats and a surprising creaminess, thanks to the 5 grams of fat found in each serving.
