This Instructable will show you how to fix a crack in your cheesecake using hot water and an offset spatula.
Step 2: Push it together
Push the crack together using your fingers. If it's a deep crack, push a little harder and from further away from the crack. If the cake sticks to your fingers, wet them with warm water.
Step 3: Sealing the crack
Step 4: Finished!
Smooth over either the cracks or the whole cake as needed. The top will be slightly lighter where the inside of the cake was pulled over the top. A topping will cover this.
