Publix Icing
I worked for Publix decorating for over 7 years. If you are looking for a recipe you will not find one that you can duplicate.
The buttercream starts as an icing base that is shipped in from their bakery distribution center. from there ingredients are added and makes 25 lbs of icing. it is then whipped on a smaller mixer by the decorators adding simple syrup and whipping 11 mins until light, fluffy and smooth.
As for the whip cream, you cannot buy the base ingredient as it also is supplied by the distribution center. they do add milk to the whip cream base and beat it until light and fluffy.
the chocolate whip cream comes in liquid form already prepared and just needs to be whipped light and fluffy.
Publix used to make the cream cheese at the local stores about 12 years ago. now it comes prepared and shipped to the stores from the distribution center.
All of the cakes are made at the distribution center and shipped in as needed frozen. That goes for many of the rolls and breads as well. They make some of the breads at the location and others are made, then frozen and shipped in to be thawed and baked as needed.
