Ice Cream: Scoops, Soft Serve, Custard and Gelato

The rulebook: what "ice cream" legally means

Ice cream is one of the few desserts with a federal definition. Under the FDA's standard of identity, anything sold as ice cream in the US must contain at least 10% milkfat — butterfat, in dairy-speak — and weigh at least 4.5 pounds per gallon. That second number matters more than it looks: it's the government's cap on how much air a company can whip into your dessert before it stops being ice cream and starts being a foam with a marketing budget.

Everything else at the counter is a variation on those two dials — fat and air — plus a third one, temperature. Here's the family, side by side:

Product	Butterfat	Overrun (air)	Typical price (2026)
Supermarket ice cream	10 - 11%	90 - 100%	$4 - 7 per 1.5-qt tub
Premium / artisanal ice cream	14 - 17%	20 - 45%	$8 - 14 per pint
Gelato	4 - 8%	20 - 35%	$5 - 7 per small cup
Frozen custard	10%+ plus egg yolks	15 - 30%	$4 - 6 per scoop
Soft serve	3 - 6%	33 - 60%	$3 - 5 per cone
Frozen yogurt	0.5 - 6%	40 - 60%	$0.60 - 0.80 per oz self-serve

Ranges compiled from FDA standards of identity, IDFA industry data and 2026 shelf prices in major metro areas.

Overrun: the air you've been paying for

Overrun is the industry's word for how much a mix expands when air is churned into it. Start with a gallon of mix, whip it into two gallons of product, and you've got 100% overrun — half of what's in the carton is air. Legal, universal and completely invisible on the label.

Some air is necessary: with zero overrun you'd be licking a milk-flavored hockey puck. But air is also the cheapest ingredient ever invented, which is why the budget brands run their overrun to the legal ceiling while premium makers keep it down around 20-45%. It's the whole reason a "cheap" tub can be the more expensive dessert per actual ounce of food.

Gelato and frozen custard: same aisle, different religions

Gelato flips the American formula: less butterfat (4-8%), much less air, and a serving temperature 10-15°F warmer than ice cream. Warmer plus denser means the flavor hits your tongue faster and harder — which is why a good pistachio gelato tastes louder than a pistachio ice cream with twice the fat. The full head-to-head lives in Ice Cream vs Gelato vs Custard.

Frozen custard is ice cream plus egg yolks — the FDA requires at least 1.4% egg yolk solids to use the name — churned with minimal air and served fresh from the machine. In the Midwest it is not a dessert, it's a denomination: Culver's has taken the Wisconsin gospel national, Kopp's in Milwaukee posts its flavor-of-the-day calendar like a liturgical schedule, and Ted Drewes has been stopping traffic on Route 66 in St. Louis since 1929. If you've never had custard within an hour of it leaving the barrel, you have an errand to run.

And frozen yogurt? Cultured milk, less fat, roughly the same sugar. It's a fine product with a dishonest halo — the self-serve froyo bar charging by the ounce is a weigh-station, not a health food store.

Soft serve: the swirl is a machine story

Soft serve isn't a recipe so much as an appliance. A lower-fat mix (3-6% butterfat) runs continuously through a refrigerated barrel and comes out at around 18-21°F — a full 10-plus degrees warmer than hard ice cream — with 33-60% overrun folded in on the way. Warm, airy, fresh from the dasher: that's the entire magic trick, and it's why soft serve eaten on the spot beats soft serve every other way.

It's also why the machine at a certain burger chain is always "broken" — those machines run a four-hour heat-pasteurization cycle, and an interrupted cycle means starting over. There's a whole economy of memes and even a live tracker built on that fact. The machinery, the mix and the broken-machine saga get the full treatment in Soft Serve: The Machine Behind the Swirl.

The $12 pint and the $6 tub: both are telling the truth

Here's the aisle in 2026: a 1.5-quart tub of store-brand ice cream for $5-6 sitting next to a single pint of Jeni's, Salt & Straw or Van Leeuwen for $12-14. Per ounce, the artisanal pint costs five to seven times more. Scam? Mostly no — it's a different product wearing the same name. More cream, a fraction of the air, real vanilla instead of "vanilla flavor," inclusions that cost more per pound than steak, and a frozen supply chain babysitting every pint from kettle to your freezer.

Where it gets less defensible is the middle: mid-market brands charging premium prices at supermarket overrun. The full teardown — ingredient costs, cold chain, and when the $13 pint is genuinely worth it — is in The $12 Pint. And note the tub next to it isn't a half-gallon anymore: the industry quietly shrank the standard container to 1.5 quarts years ago and kept the price. Shrinkflation got to the freezer aisle before the economists did.

No dairy, no sugar, no problem (mostly)

Dairy-free has graduated from sad freezer-burned afterthought to legitimate shelf war: oat, coconut and cashew bases each solve the no-cream problem differently, and only some of them scoop like the real thing. Coconut brings its own fat and behaves; oat needs help; anything without enough fat or sugar freezes into a scoop-bending slab. The base-by-base breakdown — plus what "no sugar added" actually does to texture — is in Dairy-Free and Sugar-Free Scoops.

The math at the counter

Last dial: format. A single scoop runs $5-8 in 2026, and a scoop is 4-5 ounces — meaning scoop-shop ice cream costs $16-25 per pint-equivalent, more than the fanciest pint in any grocery store. You're paying for the cone, the counter and the experience, which is fine — as long as you know that's the line item. The full price-per-ounce showdown is in Scoop, Pint or Cone.

The cheat sheet: buy the experience at the shop, buy the volume at the store, and always — always — pick up the container first. Density is the one spec no label can spin.

Frequently Asked Questions

What does the FDA require for something to be called ice cream?

At least 10% milkfat and a minimum weight of 4.5 pounds per gallon, under the federal standard of identity (21 CFR 135.110). The weight floor effectively caps overrun — the air whipped in — at roughly 100%. Products that don't meet the fat minimum have to use names like "frozen dairy dessert," which is worth scanning for on the label.

Why does gelato taste more intense than ice cream with less fat?

Three reasons: gelato carries far less air (20-35% overrun vs up to 100%), so each spoonful is denser; it's served 10-15°F warmer, so your taste buds aren't numbed; and butterfat actually coats the tongue and slows flavor release — less fat means flavors arrive faster. Density, temperature and fat all point the same direction: louder flavor.

Is frozen custard the same as ice cream?

Close cousin, not the same. Frozen custard must contain at least 1.4% egg yolk solids on top of the 10% butterfat, is churned with far less air, and is served fresh and slightly warmer straight from the machine. The yolks add richness and a dense, almost chewy texture. It's a Midwest institution — Culver's, Kopp's in Milwaukee and Ted Drewes in St. Louis are the reference points.

Is the $12 artisanal pint actually worth it?

Per ounce of actual ingredients — not air — the gap is much smaller than the sticker suggests: a 20-45% overrun pint holds nearly twice the mass of a 100% overrun tub of equal volume, made with more cream and pricier inclusions. Worth it when you'll savor it; not worth it for feeding a birthday party. For volume, a store-brand tub remains the correct answer, and there's no shame in it.
