Making Pumpkin Pavlova with Pecan Brittle. Once the meringue is out of the oven, should I refrigerate?
Did you let it sit one hour after baking in oven with heat turned off?
Then remove from oven, cool completely at room temp.
Next put in airtight metal or plastic container.
I was taught (by Cordon Bleu trained teacher) to leave at room temp before adding the whipped cream & fruit.
More recent experiments by Cooks Illustrated show you can store it in any of room temp, fridge or freezer as long as you follow the hour-long oven cool down, room temp cool down & air tight packing.
If after serving you have some left with cream and fruit/veg, yes refrigerate for about a day.
