Alton Brown's Vanilla Custard Ice Cream
Classic French-style vanilla ice cream built on a silky egg yolk custard base. Rich, creamy, and deeply flavorful, this version emphasizes proper tempering and low-temperature cooking to ensure food safety while developing custard texture. Alton Brown's approach prioritizes technique and precision--slow sugar incorporation prevents curdling, precise 170-degree heating creates the custard without overcooking eggs. Serve after machine churning for smooth, scoopable results. Perfect for summer entertaining or as a base for add-in flavors.

Tips
Whisk egg yolks and sugar slowly to avoid curdling and fully incorporate sugar before adding hot cream.
Use a thermometer to hit exactly 170 degrees--high enough to pasteurize, low enough to preserve custard texture.
Chill thoroughly in a true refrigerator, preferably overnight, before churning for best texture.
Good to Know
Airtight container in freezer up to 2 months. Ice crystals may form if stored longer.
Prepare custard base 1-2 days before churning. Churn and serve fresh for best texture, or freeze churned ice cream up to 1 week.
Serve immediately after churning for soft-serve texture, or freeze 4+ hours for scoopable consistency. Pairs with fruit, baked goods, or on its own.
Common Mistakes
Add sugar too quickly to egg yolks to avoid curdling and grainy texture
Whisk constantly while tempering to prevent scrambled eggs
Use a thermometer to avoid overcooking custard above 170 degrees, which breaks emulsion
Substitutions
lighter custard
FAQ
Can I use pasteurized eggs instead of raw?
Yes, pasteurized eggs are safer and work identically. The 170-degree heat further ensures safety. Pasteurized egg yolks may be slightly thicker initially but blend smoothly with sugar and cream.
What if my custard breaks or looks grainy?
Strain through fine mesh sieve to remove any cooked egg pieces. If severely broken, reheat gently to 160-165 degrees while whisking and cool again, though texture may be compromised. Prevention through slow tempering is key.
How long does the mixture need to chill before churning?
At least 8-12 hours, preferably overnight, until it reaches 40 degrees or below. Colder mixture churns more efficiently and produces smoother, less icy texture with better mouthfeel.
