Critical tips

Don't overbake

• 12-15 minutes max
• Cake must be moist to roll
• Overbaked = cracks badly

Roll while warm

• Hot from oven, onto towel, roll
• Sets the roll shape
• Cool rolled, then unroll/refill

Powdered sugar towel

• Prevents sticking
• Don't skip this
• Generous dusting

Don't fight cracks

• Some cracking is OK (bark!)
• Ganache covers everything
• Cracks add realism

Meringue mushrooms

Quick version

1. Whip 2 egg whites + 1/2 cup sugar to stiff peaks
2. Pipe small mushroom caps and stems on parchment
3. Bake 200°F for 1.5 hours (dry, crisp)
4. Attach caps to stems with melted chocolate
