Recipe FAQs and Expert Tips

How do I cut this cake?

To slice this cake making nice clean cuts, run a sharp knife under very hot water for a moment, dry and quickly but carefully make a cut for the first slice. Rinse the knife under very hot water, dry and repeat cutting as before with every slice.
