tips for a sure result
-
the dark whipped cream must be really chilled; if it is lukewarm, it won’t whip.
-
when whipping both creams, watch that you don’t overbeat them – they will start to curdle.
-
don’t bake the sponge for too long so it stays moist; every oven heats differently, check with a skewer.
