before leveling your cakes do you do something to them... ? Put them in the fridge for a bit? anythings....
for leveling, no, I don't put them in the 'frig. I level them in the pan as soon as I take them out of the oven, flip them out of the pan and if they need add'l trimming, I do it then.
If I'm torting a cake, I like them to be a bit frozen.
I level the top of mine in the pan prior to flipping them out. That way i use the pan edge to keep my knife straight. If I torte them, I freeze the layer so its easier to cut then slide a cake board between the layer to lift it off.
Hey, freezing a bit makes sense, that way it doesn't crumble when you cut it top off. I hate it when it does that.
