The Science of Ice Cream and Gelato

Move beyond basic recipes to master the molecular balance of fat, sugar, and air for professional-grade texture in your 2-liter churner.

Like Duolingo, but for The Science of Ice Cream and Gelato. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

71 levels across 8 sections, about 142 minutes end to end, roughly 28 days at five minutes a day. It moves through Immediate Texture Upgrades, The Chemistry of Sweetness, Fat and Protein Dynamics, The French Custard Method, Authentic Italian Gelato, Flavor Architecture, Stabilizers and Texturizers, and The Physics of Storage. It assumes you already know the basics.

What you'll learn

Key ideas in The Science of Ice Cream and Gelato

  • Fat crystallization during aging
  • Protein hydration in ice cream
  • Cold-aging allows fat-soluble aromatics like vanilla bean to fully infuse
  • A base at 40°F (4°C) freezes much faster than a room-temperature base
  • How fat crystallization during aging affects the final texture
  • Spices and botanicals mellow and integrate during the long rest period
  • Faster freezing prevents small ice crystals from merging into large grains
  • The role of protein hydration in preventing iciness
  • The relationship between base temperature and ice crystal growth
  • A 24-hour aged base is noticeably thicker due to fat and protein changes
  • The effect of aging on flavor intensity
  • Short aging results in a thinner base that lacks structural stability
  • Distinguishing the physical characteristics of short vs. long aging
  • Ice cream expands as air is incorporated during the freezing process
  • Canisters must be cold enough to flash-freeze the base on contact
  • Overfilling blocks air from entering the mix, resulting in dense, icy texture
