There’s a real skill when it comes to making macarons, something I didnt quite appreciate when embarking on this baking challenge. I was feeling rather cocky, perhaps high on my last French-baking success. I decided that I didn’t want to make just regular macarons, I wanted animal macarons! I wanted bears, rabbits, unicorns and more!

But alas, I was rather foolish, and what follows is a what not-to-do guide when making macarons.

The Ideal Macaron

Let’s for a moment think about macarons in terms of their shells. The perfect macaron shell must satisfy two requirements: cosmetic and textural. Cosmetically, the macarons must have a spherical, domed shape, the top of which is shiny, smooth and void of cracks. The shell must also contain “feet”, a chewy base to the shell that has a rough, sandy look.

Texturally, the outer macaron shell should be crunchy, while the inside should be marshmallowy and chewy. This crunchy-chewy textural dichotomy makes macarons moorish.

The impossibly high cosmetic and textural standards of a macaron make them a bit of a nightmare to bake, especially when considering the simple-looking recipe. Most macarons are made by mixing almond meal, icing sugar and egg whites to form a paste. A meringue is then incorporated into the almond paste to form a batter, which is then piped and baked to form macaron shells.

At a distance, this recipe seems rather fool-proof, but I assure you, that many things can go wrong! From beating to piping, creating the perfect macaron shell requires a great deal of skill. Thankfully, science is here to help us iron out the most common mistakes.

Below, I identify three types of ill-formed macarons, that I call mistakarons, and simple remedies to success.

Mistakaron 1: Pubescent Shells

When you’ve spent several hours baking, it can be disheartening to find your macarons resembling your former pubescent self: skin crackled, pimpled and blistered. But it happens. Shells can come out of the oven with cracks, a bumpy surface and most insidiously, a small alfafa-esque peak.

Pubescent mistakaron. The shell is rough, cracked and has an insidious peak in the middle. This is most spinning top than macaron.

The good thing is, beauty is only skin deep, and these macarons (that you’re really only interested in because of their personality) still taste crunchy and chewy. But if you do want to superficially spruce your shells, I have one word for you: macaronage.

Macaronage is the term used when combining the meringue with the almond paste. If the macaronage process isn’t done quite right, it can lead to either very dense or very flat macarons. The former is the reason for your pubescent mistakarons.

During the macaronage process, you need to let go of every instinct that you have as a baker. Intuition tells us that when incorporating a light and airy meringue into a gooey paste, we need to retain as much air as possible. So as bakers, we carefully fold-in the meringue, until it is just incorporated. I URGE YOU THOUGH, LET IT GO!

The macaronage process actually requires you to BEAT OUT some of the air in the meringue. This will feel like the most criminal moment in your entire baking life, but trust me, it’s what the macarons want, no, NEED! An airy macaron batter is actually quite thick and will hold it’s shape a little too well. When you go to pipe this thick batter, a small peak will be left behind which will not collapse. Therefore, the shell will come out like a spinning top.

This batter is far too thick. You can see that that are little peaks on each, which will not settle. This is a sign that your macaronage process was incomplete.

To avoid this, the meringue should be mixed with some force. As you fold the meringue into the almond paste (using a spatula), press the mixture down on the sides of the bowl. This will deflate some of the air. Keep doing this until you batter is smoother. Some people say to achieve a batter that resembles ‘magma’, but the last time I checked, most of us aren’t living next to active volcanoes with a safe, yet generous supply of lava. So I’ll share some practical advice with you instead that only involves a teaspoon.

Take a teaspoon of the batter and put it on a plate. Initially, you will get a heap of batter with a tiny peak at the top. If this peak collapses within about 10 seconds, the macaronage process is complete and the batter is ready. If the peak is still present, then keep working the batter.

Mistakaron 2: Footless shells

When Kevin Bacon told us to get “Footloose”, this is not what he had in mind. Macaron shells that are flat, cracked and have no feet are an unfortunate sight and don’t even have the redemption of tasting delicious. They’re ugly inside and outside. However, assuming that you have made the batter correctly, it is easy to fix.

Footless shell. While the shells have a smooth surface, they’re also very flat and very cracked.

Feet form due to expansion of air during baking. When the macaron batter is placed in the oven, the mixture heats and the air inside expands. As the air expands, the macaron rises, and feet begin to form. This process is interrupted if the air escapes, which occurs if the macarons have not been properly rested.

Resting allows the external surface of the macaron to dry out, forming a “skin”. This skin traps the air during baking, allowing your macaron to rise. Flat and cracked mistakarons occur as the skin has not formed. During baking, the air escapes from the top, cracking the surface, resulting in flat pancakerons.

Once your macarons have been piped, a resting time of 1 – 1.5 hours is usually adequate for skin formation. To check that your macarons have formed a skin, gently place your finger on the batter. If no batter sticks to your finger, it is ready.

These macarons have not passed the finger test

Mistakaron 3: Mis-baked shells

Baking time is incredibly important. You need to give enough time for your macarons to rise and form feet. You also need to allow time for those feet to set, without burning your macarons.

Somehow, in my infinite prowess as a cook, I managed to achieved both flat AND burnt macarons. To achieve this miracle, I put rested shells in the oven and excitedly watched as feet started to form, but as I took them out, the feet began to collapse almost immediately. So I popped them back in. However, instead of reformed feet, I was left with a burnt shell.

These shells came out looking rather burnt, a shade away from the pinky hues I was hoping for. This burnt colour is great if you want brown macarons…

This little misadventure demonstrates the importances of baking time. The recipe I used called for 12 minutes at 150°C. However, my feet didn’t quite set in this time frame. So 1 or 2 minutes longer would’ve been better. Any longer, and the macaron will start to burn.

I recommend doing a practise run in your oven. Test a small batch first and check how long it may take. Remember, every oven is different and temperatures can vary drastically between models.

If all else fails: blitz!

Despite my tips on avoiding mistakarons, you may still be left with turmoil on a plate. Alas, making macarons takes a lot of skill. But even if your shells are cracked or flat, you can still use them in inventive, if not slightly scandalous, ways.

With your cracked or flat macaron shells, place them in a food processor and blitz into a fine or coarse powder. This sounds sacrilegious but this macaron dust makes an excellent addition to a range of desserts. If you are going down this way, bake your macaron shells for a little longer in the oven, so they’re not too gooey.

The macaron dust adds great crunch to a dessert. Here’s some ideas:

  • sprinkle on top of iced cupcakes, donuts, eclairs, etc
  • stir through fruit and custard
  • incorporate within ice cream
  • crumb chocolate-dipped strawberries

It’s quite impressive when you tell your friends that you have used macaron dust in a dessert. It makes your mistakaron feel 1000% more luxurious. So whether you’ve made macarons or mistakarons, you will be a winner!

Happy baking! If you have any other macaron tips or stories, share them in the comments. And if you have any other ways to use macaron dust, I’d love to hear it too! I leave you now with some chocolate macarons that I made.

  1. I’m on my sixth batch and still can’t seem to get it right! My batter seems almost fluffy once I pipe them, so my final guess is that I’m not getting enough air out during macronage. Thanks for your tips, I can’t wait to try again!

    1. Hey Rebecca. Thanks for the comment!
      It does sound like perhaps the batter is still a little too thick. If you’re unsure if you have the correct consistency of the batter, do a few teaspoon tests before you put it in the piping bag. Good luck in your next baking adventure!

  2. Just did my 6th test batch of macarons today and i thought i was gonna get it right this time, but ended up with hollow shells again ans cracked top. Ive watched lots of videos on macronage and it’s really confusing what’s the real true way of doing it. Some dont press the batter on the side of the bowl, some do it like flattening the batter really hard taking the air out. What should it be really? It’s really frustrating. I managed to make one before but without feet but at least they’re not hollow. I forgot what i did though.. i need help!

    1. Im sorry to hear that Jackie! If your shells have cracked, it usually means that the batter wasn’t dry enough before you put it in the oven. Make sure that the piped batter has formed a dry ‘skin’ before placing it in the oven. This ‘skin’ acts as a barrier, preventing air from escaping as the macaron bakes, hence preventing cracks. (I once had to wait 2 hours before a dry skin formed!)

      In terms of macronage technique, either way is fine. The consistency of the batter is the main thing to focus on. As you are macronaging and you think you are getting close to the correct batter consistency, get out a teaspoon of batter and place it on a plate. If this batter settles into a sphere/oval shape within about 10 seconds and there’s no residual ‘peak’, then its good to go. If not, keep macronaging, testing regularly to make sure you dont over work your batter. Only after the batter passes the teaspoon test should it be placed in a piping bag. (If you overwork your batter, there wont be an air left, and so your macarons won’t rise and won’t form feet)

      Good luck! I hope you’ll try this again. Its incredibly satisfying when it does work!
