Why can't I find any creamy or custard like filling recipes that don't require refrigeration? I see cakes and pastries with custard fillings in the bakery section of my grocery store that are not refrigerated.
Those are the products of modern chemistry. Although they are made from food products, there are thickeners, stabilizers, and preservatives that keep them from separating or spoiling without refrigeration.
There are sleeved fillings that are custard-like, which do not require refrigeration. They can be purchased in smaller quantities from several online sources.
sleeved fillings! Got it! Thank you so much!!
