I’m always on the lookout for new sources of flavorings and extracts to use in low carb recipe conversions. LorAnn Oils makes flavorings specifically for ice cream and milkshakes called “Flavor Fountain Flavors.” They’re available in small serving sizes, are unsweetened, and contain both flavoring and coloring.
I’m assuming these flavorings are water soluble, unlike the essential oils products they also make. Therefore, the banana flavor fountain product will probably work a lot better than other kinds of banana flavorings or extracts. I’ve tried the cake batter and pistachio so far and they both result in an incredible ice cream. I purchased a whole bunch of these, so it’s a safe bet that I’ll be using them in future ice creams quite a bit.
I buy these flavorings from Netrition. The have a huge selection of these on their website.
