So far, I've used the Wilton all-crisco recipe partly because it has a long shelf life at room temperature. If I switch and try the buttercream dream with real butter, how long will it keep at room temperature (such as on a cake) or in the fridge if I make it ahead of time.

Thanks!

bump . . .

Anyone?

about a day out of fridge. 5 days in fridge, 6 months in freezer

I would only keep it out on the counter for a couple of days no longer. I keep it in the fridge for about a week.

Good to know, Thanks!

The salt in your recipe acts as a preservative. You can keep it out for a few days with no problem.

The salt does work as a preservative. As told by my health inspector its the sugar that is the preservative. You decide what you feel is best.
Good luck

Q. Why is salt a good food preservative?


A. Salt is considered antibacterial because it restricts bacterial growth in many foods. It preserves foods by lowering the amount of "free" water molecules in foods. Bacteria need moisture in order to thrive, so without enough "free" water, they cannot grow well in foods that contain salt.

How many people use salt in there buttercream? I never do, dont know why I just dont.

Every buttercream recipe I've ever seen uses salt. And I usually use salted butter. Why is this such an issue for you?

I only use about a teaspoon of salt to a recipe (and unsalted butter), not sure if that counts as enough to combat bacterial growth, but I've had my cakes sit out for a few days (I use water for the liquid) with no ill effects.
