what's the scientific explanation for this?Why do you have to chill the bowl first when making whipped cream by hand?
So that it wouldn't melt or lose it's puffiness.Why do you have to chill the bowl first when making whipped cream by hand?
Because if the bowl is to warm the cream will not whip it will stay like milk it will not get fluffy..
You don't have too if its not real warm in your kitchen, but it will take longer for the cream to whip...best to have really cold cream, bowl and beaters to have it whip quickly...I don't know the absolute science behind it, but I know its true.....get an electric mixer to whip it, using a wire whisk serves the purpose, but you need good arm strength and stamina!!!
