Whip heavy cream in a stand mixer. For small servings, you can whip cream in a jar with a handheld milk frother. Whip the cream to just soft or medium peaks. Whip liquid stevia into the heavy cream at the end.
Step 2
Squeeze fresh orange juice into the bottom of a serving glass (about 2 ½ TB per glass). Spoon the whipped cream into the orange juice. You can reserve a little whipped cream to spoon on top of the soda later.
Step 3
Gently pour flavored or plain sparkling water into the glass (about 8 ounces or more per serving). Be careful, the cream will foam and rise rapidly! You can add more liquid stevia to the drink at your discretion. Drink immediately.
