Macaron
An almond-meringue shell whose every characteristic feature — the smooth top, the foot, the hollow — is decided by how far the batter was deflated on purpose.
Also called french macaron (INTERNATIONAL), macarons (INTERNATIONAL)
A macaron shell is an egg-white foam stiffened with sugar and loaded with ground almonds, piped and baked until it sets with a smooth top and a ruffled base — the foot.
WHAT MAKES IT DIFFICULT IS THAT THE CRITICAL STEP IS DELIBERATE DAMAGE. Macaronage is the folding that knocks a measured amount of air back out of the meringue. Too little and the batter holds peaks, the piped shell keeps its nipple and cracks as it expands. Too far and the batter runs, spreads thin and bakes without a foot. There is no external signal for the endpoint beyond how the batter flows, which is why the technique is described by behaviour rather than by a number of folds.
THE FOOT IS AN ESCAPE ROUTE. The top of a piped shell dries into a skin; when the interior expands, it cannot go up through the set surface, so it lifts the edge and pushes out sideways. That is all a foot is — evidence that the surface set before the interior finished expanding, which is the same mechanism that cracks a cake top, here turned into a feature.
HOLLOW SHELLS follow from the same geometry. If the interior expands hard and then contracts as it cools, a gap is left under the set top. It is a structural outcome rather than a moral failing, and it has several routes: over-whipped meringue, an oven too hot early, and under-baking that leaves the inside too soft to hold the top up.
BakeHQ makes no claim about humidity. It is the most-repeated explanation for macaron failure and BakeHQ has read no controlled evidence for it, so it is recorded as a widely-held belief rather than a mechanism.
What it should be like
- Structure
- Smooth domed top, ruffled foot, fine even interior
- Tenderness
- Crisp shell yielding to a soft interior
- Crust
- Matt and unbroken — cracking is the characteristic fault
How it keeps
Improves for a day or two after filling and then declines. The shell is dry and the filling is not, so water migrates from filling to shell until they equalise — which is what turns a brittle shell into the intended texture, and what eventually makes it soggy.
The direction follows from the water-activity account rather than from a study of macarons. BakeHQ states no maturing time, because that depends on the filling and no figure read here supports one.

Where it comes from
Traditional account
A long-standing account of how something originated or was done. Recorded as tradition, which is not the same as recorded as fact.
The two-shell filled macaron is French. Almond-and-egg-white confections are older and appear in Italian and French monastic and court baking alike; the modern form is a later development.

Macaron and macaroon are different things
This is a genuine ambiguity rather than a spelling preference, and collapsing it would send readers to the wrong page.
A MACARON is the almond-meringue sandwich described here: a piped shell with a foot, filled.
A MACAROON, in most British and American usage, is a coconut confection — dense, craggy, often dipped in chocolate. In some traditions it names an almond biscuit that is closer to the macaron’s ancestor and still has no foot and no sandwich.
BakeHQ records “macaroon” as an alias on this page because a great many readers type it meaning this, and the alias carries a note saying what it usually means instead. What it does NOT do is treat the two as one product.
Feet are evidence of a mechanism, not proof of technique
“If it has feet you did it right” is the most repeated macaron heuristic and it is only half true.
A foot means the surface set before the interior stopped expanding. That is necessary, and it is compatible with several bad outcomes: a shell can have a fine foot and be hollow, or have a foot and a cracked top, or have a foot and be over-spread because the batter was folded too far.
So feet are a check on one thing — that the skin formed and the oven was hot enough at the start — and tell you nothing about macaronage, meringue stability or bake endpoint. Judging a macaron by its feet alone is why the same person can produce footed, hollow shells for months.

Part of
A meringue-based biscuit. Filed here because that is where readers look and because its structure is a baked foam rather than a cake crumb; the classification is pragmatic and the record says so.
What this product needs done
Aeration
An egg-white foam, and the only lift there is. Macaronage then removes a measured part of it on purpose.
Structure building
Egg protein setting around sugar and ground almond. There is no flour and therefore no gluten network at all.
Gas retention
The protein film around each bubble holds what is left of the air until the heat sets it. Over-folded batter has broken too many of those films to hold anything, and bakes without a foot.
Techniques this product depends on
Macaronage IS folding, used to remove air rather than to preserve it — the only place in the catalogue where the technique’s purpose is inverted.
The meringue comes first, and its stability decides how much folding the batter can survive.
Characteristic ingredients
The foam, and the only structure.
Bulk and flavour. It has no gluten to contribute, which is why the shell has no crumb.
Things that go wrong
Meringue is weeping, chewy or will not whip
The meringue is the macaron’s structure, so its faults are the macaron’s faults.
Notoriously sensitive to oven position, and one of the commonest explanations for inconsistent trays.
Commonly confused with
A macaron is an almond-meringue sandwich shell with a foot. A macaroon is generally a coconut confection with neither. BakeHQ carries the alias because readers type it and keeps the products distinct; this edge exists so the ambiguity is visible on the page rather than resolved silently.
Glossary terms defined here
Macaroon
The entry exists to keep these apart, not to join them. It points here because most people typing the ambiguous word mean this product, and it says plainly that the other meanings are different confections BakeHQ does not carry.
