Some suggest the following procedure after baking. Immediately cover the cake with a kitchen towel, place a round cake rack on top of it and tumble onto the cake rack covered with the kitchen towel. Remove the baking tray immediately and let the Easter cake upside down cool down for about 45 minutes. Then turn the cake back and let it continue to cool down.
If you think this procedure is too risky then just let it cool down remove and remove it from the tart pan. It might be the case by this procedure that the dough is not as crusty as with the other proposal.
