Phase 1: Coffee & Chilling Prep (5 minutes)

Do this first - coffee needs to cool

Make Espresso Coffee Mixture (Breville Portafilter):

• Grind beans fine, tamp firmly
• Pull 8-10 double shots (about 2.5 cups total espresso)
• Stir in 3 tablespoons white granulated sugar + 1 tablespoon vanilla extract
• Pour into large shallow dish
• Set aside to cool to room temperature (critical - hot coffee will melt your cream later)

Tip: If espresso is too strong, add 1/4 cup warm water to dilute slightly

Phase 2: Mascarpone Base - All at Once (15 minutes)

Make entire batch together, then divide

Set Up Double Boiler:

• Fill large pot with 2 inches water, bring to gentle simmer
• Place heat-proof bowl on top - water should NOT touch bottom of bowl
• Water should barely bubble, not rapid boil

Master Egg Mixture (Full Recipe):

• Separate 9 large eggs (yolks in small bowl, whites in medium bowl)
• Add 1 cup white granulated sugar to egg yolks
• Place bowl over simmering water (double boiler)
• Whisk constantly for 10-15 minutes until mixture reaches "ribbon stage"

What's ribbon stage? Mixture becomes pale yellow, doubles in volume, and when you lift whisk, mixture falls in ribbons that hold their shape for 3-4 seconds before dissolving back

• Remove from heat, let cool 5 minutes

Tip: Don't let bowl touch water or eggs will scramble. Keep whisking constantly!

Mascarpone Integration:

• In large mixing bowl, combine all 25 oz room-temperature mascarpone
• Add 2 teaspoons vanilla extract
• Gradually fold in the cooled egg-sugar mixture until completely smooth
• Don't wash bowls yet - you'll need them for whipping

Tip: If mascarpone is still cold and lumpy, microwave for 10-15 seconds to soften

Phase 3: Aeration Components (10 minutes)

Use chilled bowls and beaters from freezer

Whip Egg Whites:

• Using clean, chilled beaters, whip 9 egg whites to stiff peaks (about 3-4 minutes)
• Peaks should stand straight up when beaters are lifted
• Set aside in refrigerator

Tip: Any trace of yolk will prevent whites from whipping - wipe bowl with lemon juice if unsure

Whip Heavy Cream:

• Switch to second set of chilled beaters (or wash and dry first set)
• Whip 1.5 cups heavy cream to medium peaks (2-3 minutes)
• Should hold soft peaks but still be slightly jiggly - easier to fold
• Keep chilled

Final Mascarpone Mixture:

• Gently fold whipped cream into mascarpone base using large spoon
• Then fold in egg whites in 2 additions - be gentle to keep air
• Divide mixture: 60% for 9x13 pan, 40% for 9x9 pan (eyeball it)
• Keep both portions covered in refrigerator while assembling

Tip: Fold from bottom up, rotating bowl - don't stir or you'll deflate the mixture

Phase 4: Strategic Assembly (15 minutes)

Work quickly but methodically

Coffee Dipping Setup:

• Ensure coffee mixture is completely cool (test with finger)
• Have both pans ready side-by-side
• Count out ladyfingers: 38-40 for 9x13, 26-28 for 9x9
• Have cocoa powder and fine strainer ready

Tip: If coffee is still warm, add ice cubes and stir, then remove cubes

Assembly Strategy - Both Pans Simultaneously:

Step 1: First Ladyfinger Layers

• Quickly dip each ladyfinger in coffee for 1-2 seconds only (don't soak)
• Arrange in tight single layer in both pans simultaneously
• 9x13: Use 19-20 ladyfingers (should fit snugly)
• 9x9: Use 13-14 ladyfingers
• Break ladyfingers to fit corners if needed

Tip: Work fast - soggy ladyfingers will fall apart

Step 2: First Cream Layers

• 9x13: Spread half of larger mascarpone portion (about 1.5-inch thick)
• 9x9: Spread half of smaller mascarpone portion
• Use offset spatula to smooth evenly
• Dust both generously with cocoa powder using fine strainer

Tip: Don't press down while spreading - just guide the cream gently

Step 3: Second Ladyfinger Layers

• Dip remaining ladyfingers in coffee (1-2 seconds each)
• Create second complete layer in both pans
• 9x13: Use remaining 19-20 ladyfingers
• 9x9: Use remaining 13-14 ladyfingers

Step 4: Final Cream Layers

• 9x13: Spread remaining larger portion, mounding slightly in center for height
• 9x9: Spread remaining smaller portion, mounding for height
• Smooth tops with offset spatula but leave slight dome shape

Step 5: Final Presentation

• Generously dust both with cocoa powder through fine strainer
• Cover tightly with plastic wrap (press plastic to edges but don't let it touch surface)

Tip: Put toothpicks in corners to hold plastic up if needed

Phase 5: Strategic Chilling & Serving

Immediate Chilling:

• Refrigerate both pans immediately
• Minimum 6 hours for structure, optimal 24-48 hours for flavor
• Longer chilling = better flavor integration and much easier slicing

Serving Preparation:

• Remove from refrigerator 15 minutes before serving for easier cutting
• Use sharp knife dipped in warm water, wiping clean between cuts
• Dust with additional cocoa just before serving if desired

Tip: Cut with straight down motion, don't saw back and forth

Pro Efficiency Tips

Time-Saving Hacks:

• Coffee first - needs 20+ minutes to cool completely
• Room temperature mascarpone mixes 10x easier than cold
• Under-whip cream slightly - over-whipped cream breaks when folded
• Work with both pans side-by-side to minimize steps

Equipment Efficiency:

• Same bowl sequence: egg yolks → mascarpone → final mixture (no washing)
• Chill all whipping equipment beforehand for better results
• Use wide shallow dish for coffee - more surface area for quick dipping

Quality Maximizers:

• Don't over-soak ladyfingers - they absorb more moisture during chilling
• Mound final layers slightly - they settle but maintain impressive height
• Plastic wrap tight to edges prevents skin forming and refrigerator odors

Make-Ahead Strategy:

• Best flavor at 24-48 hours after assembly
• Coffee mixture can be made day before and refrigerated
• Mascarpone mixture can be made 4 hours ahead and kept chilled

Expected Results

What You'll Get:

• 9x13 pan: 15-18 generous servings
• 9x9 pan: 9-12 generous servings
• Total height: 3-4 inches per pan with double layers
• Flavor peak: 24-48 hours after assembly

Troubleshooting:

• Lumpy mascarpone = too cold, warm slightly
• Deflated mixture = over-mixed or warm coffee
• Soggy ladyfingers = soaked too long
• Won't slice cleanly = needs more chilling time

This method creates two towering tiramisus that will absolutely dominate any gathering!
