AWanting to use this filling but does it require refrigeration? 1/2 cup butter Dash of salt 1 cup brown sugar 1/2 cup evaporated milk 2 cups powdered sugar 1/2 teaspoon vanilla extract

Thank you for your responses

I'm not sure about the difference in refrigeration needs between evaporated milk and regular milk, but I think they're the same--i.e., both have to be refrigerated.  I usually leave my american buttercream sitting out without refrigeration, and it has almost a half cup (5-6 tbsp) of milk in it, but it also has two pounds of sugar. Your filling has about half that sugar-to-milk ratio, so I'd say you should refrigerate it.

 

How's that for a non-scientific and unsubstantiated opinion?  :p

 I was wondering about this, too. There's a high amount of liquid in that recipe. Is it a cooked filling?

Evaporated milk comes in a can that sits on the shelf, so I would say no.  I always pop it in after I open it, but I'm not sure if it says that on the can or not...

AIt is a cooked filling. It is a praline filling. It is heated to 232 degrees before taken off and mixed with the sugar

It is a cooked praline filling. I've just never used evaporated milk so wasn't sure if it could be kept out. It has to be cooked to 232 degrees them taken off to add the powdered sugar. The recipe I found for it did not specify on storage
