What is a baking "emulsion"?
Emulsions are water-based, alcohol-free alternatives to extracts. Instead of using alcohol, the flavor is micro encapsulated in natural stabilizers and suspended in water. The encapsulation enables the flavor to not lose its integrity when exposed to high heat.
Which means....Use baking emulsions instead of extracts with better results!
When it comes to flavoring, professional bakers almost exclusively use emulsions over alcohol-based extracts.
Emulsions have a more potent, robust flavor.
Won't "bake-out" when exposed to heat
Princess Cake and Cookie baking emulsion has a light, nutty taste accented with undertones of citrus and rich vanilla. Use it wherever you want to impart a creamy flavor. Delicious as a flavoring for butter cream frosting.
Flavor combination: Vanilla + Almond + Lemon
I've never used the Princess, I have used the Butter-Vanilla, Buttery Sweet Dough & the Coconut. I just use as it says on the bottle, when baking use as your recipe directs. When not baking or cooking (as in buttercream) use slightly less then directed.
