Tips & Technique Glossary

Custard Basics

Most Standard and Cuisinart recipes start with a cooked custard base: cream and milk heated with sugar, tempered into egg yolks, then cooked to 170–175°F. The key is patience. Don’t rush the heating, stir constantly once the eggs are in, and strain the finished custard through a fine-mesh sieve to catch any bits of cooked egg. A properly made custard is the foundation of dense, smooth ice cream.

Tempering Eggs

Tempering means gradually raising the temperature of your egg yolks by whisking in small amounts of hot liquid before combining everything. This prevents scrambling. Ladle about half a cup of the hot cream mixture into the yolks while whisking, repeat once more, then pour the warmed yolk mixture back into the pot. Work steadily but don’t panic — as long as you’re whisking, you’re fine.

The Ninja Creami Difference

Ninja Creami recipes don’t use cooked custard. Instead, they rely on cream cheese as a stabilizer, which gives body without cooking. The base freezes solid for 24 hours, then the machine shaves and spins it into ice cream. If the result looks powdery or crumbly after the first spin, run a re-spin cycle — this is normal, not a mistake. Mix-ins go in after the initial spin, dropped into a hole dug in the center, then processed with the MIX-IN setting.

Alcohol and Freezing

Alcohol lowers the freezing point of your base. That’s why each method specifies exact amounts — too much and the ice cream won’t set; too little and you lose the flavor. Ninja Creami recipes use less alcohol because the base must freeze completely solid. Standard and Cuisinart recipes can handle slightly more because churning incorporates air into the mixture as it freezes. Don’t freelance the quantities.

Churning Tips

For Cuisinart frozen bowl machines, the bowl must be frozen for at least 24 hours. Shake it before use — if you hear liquid sloshing, it needs more time. Always turn the machine on before pouring in the base to prevent the custard from freezing to the bowl walls. For traditional ice cream makers, follow the manufacturer’s timing, but expect 20–25 minutes for most of these recipes.

Storage

Press plastic wrap directly onto the surface of the ice cream before sealing the container. This prevents ice crystals from forming on top. Homemade ice cream is best within 1–2 weeks. If it’s been in the freezer a while and feels rock-hard, let it sit at room temperature for 5–10 minutes before scooping.

Glossary

Bloom: To soften gelatin in cold liquid before heating, or to gently heat chocolate until it begins to melt.
Chiffonade: Thin ribbons of herbs or leafy greens, cut by stacking leaves, rolling tightly, and slicing crosswise.
Churning: The process of freezing and aerating an ice cream base simultaneously by stirring it in a cold vessel.
Coats the back of a spoon: A custard test — dip a spoon in, run your finger across it, and if the line holds without dripping, the custard is done.
Cream cheese stabilizer: In Ninja Creami recipes, softened cream cheese, whisked with sugar, adds body and smoothness without cooking a custard.
Custard base: A cooked mixture of cream, milk, sugar, and egg yolks that forms the foundation of most Standard and Cuisinart ice cream recipes.
Deglaze: Adding liquid to a hot pan to dissolve browned bits stuck to the surface.
Emulsify: To combine two liquids that don’t naturally mix (like fat and water) into a stable, uniform mixture.
Fine-mesh sieve: A strainer with very small holes, used to catch lumps of cooked egg or solids from a custard.
Fold: To gently combine a lighter mixture into a heavier one using a spatula in a sweeping, turning motion.
Frozen bowl: The removable insert of a Cuisinart-style ice cream maker that must be frozen solid (24+ hours) before use.
Infuse: To steep an ingredient in a liquid to extract its flavor, then strain it out.
MAX FILL line: The marked line inside a Ninja Creami pint container indicating the maximum amount of base — do not exceed it.
Mix-in: Solid ingredients (nuts, candy, cookie pieces) added to ice cream after initial churning or spinning.
Overrun: The amount of air incorporated into ice cream during churning — more overrun means a lighter, fluffier texture.
Re-spin: A second cycle on the Ninja Creami, used when the first spin produces a crumbly or powdery result.
Ribbon stage: When a whisk is lifted from beaten eggs and sugar, the mixture falls in a thick, slowly dissolving ribbon.
Scald: To heat liquid just until small bubbles appear around the edges, below a full boil.
Steep: To soak an ingredient in hot liquid to extract flavor, then strain.
Temper: Gradually raise the temperature of a cold ingredient (such as egg yolks) by adding hot liquid while stirring to prevent curdling.
Zest: The outermost colored layer of citrus peel, removed with a microplane or zester — avoid the white pith beneath, which is bitter.
