My whipped cream looked grainy when I was frosting my cake! What happened? I did color the cream was that it?
you beat it too long.
...And if you beat it loooong enough - you'll get butter.
Ask me how I know.
Gee, Jan, personal experience??
You can only imagine the many mistakes I made teaching myself to bake and make other desserts (at 9 y.o.a.).
I was about twelve at the time of the Glorified Butter, er Rice dessert I was attempting...
Experience is definitely what you get - when you don't get what you wanted.
