Nothing drastic, but if I whip some double cream, how long would it stay thick for ? I am doing some bits and pieces for the oldies today ... and plan to top some HM butterscotch with cream whipped up with mashed banana and maple syrup .... how does that sound ? I will be leaving the house about 2 pm.
I solved my query about what to fill the vol-au-vent cases with .... when I got them out of the freezer, I found they were already filled

They only need warming up in the oven.
