Let's start with: Macarons are not as scary to make as you think. Yes, it's not an easy recipe, but it's far from impossible and actually fun to make.
I use this recipe (I recommend watching the video!), with a few tweaks, and I've added notes from others. Personally, I think regular macarons are too sweet, so I like having a more bitter or tart filling to balance them out.
This recipe yields approx. 23 macarons (46 "cookies") of 2 inches in diameter. But I generally vote for smaller macarons (and more yield!).
Italian Meringue
230 gr granulated sugar
230 ml water
85 gr (old) egg whites
Paste
110 gr (sifted) almond flour
110 gr (sifted) powdered sugar
40 gr (old) egg whites
Gel food coloring (avoid liquid)
Filling: Raspberry Ganache
100 gr raspberries
100 gr dark chocolate
Old egg whites: Separate whites 3-5 days early, store in a Tupperware, and refrigerate. Bring to room temperature before use.
Print (or draw) the circles on parchment paper for two baking sheets to help you when piping.
A fan can help with the drying process.
If you have an electric oven (not me), use the Fan Only setting.
To nail the best oven temperature for macarons with your oven, check for these signs after baking:
If they brake at the top, they weren't dry enough before making.
If they don't get the nice little skirt of macarons, your oven was a bit too cold.
If they have crumbles, you probably didn't mix the dough enough.
If they spread too much, the meringue may have been too liquid, or you overfolded it into the paste.
If they have marks at the top (from piping), the dough was too thick.
Italian Meringue: For macarons, you need a weak meringue, which you create by using old (refrigerated) egg whites. All other meringue rules apply. See full recipe here, but in short:
Make the syrup by heating up the sugar and water.
Start whisking the egg whites with a mixer when the syrup is almost ready (at 116°C to be specific).
Pour the syrup in a thin stream down the side of the bowl and whisk until shiny and warm.
Paste: While you make the meringue, prepare the "paste" (or "dough"?) of the macaron.
In a bowl, pour the 40 grams of (aged) egg whites and mix in your gel food coloring. Whisk well to avoid streaks in your macarons. Note that you'll later add the meringue to this paste, so the color will be significantly toned down.
Add the sifted almond flour and powdered sugar. Combine with a rubber spatula until it turns into a dense, uniform paste. If you want to add more coloring to your macarons, now is your last chance.
Some recipes even call for pulsing the almond flour and powdered sugar in a food processor to make the texture even finer, and then sifting them multiple times. But that ain't me.
Macaronnage (I think that's the technical term for the combination of the meringue and the paste)
Fold the meringue into the paste in 3-4 additions.
The consistency here is key: Fold until the batter drips slowly from the spatula. That middle ground between liquid and solid, where it slightly holds its shape but settles in the bowl.
Note that it's better to have too thick a macaronnage than too liquid. If it's too liquid, they won't hold their shape, but if it's too thick, a few extra folds will bring it down. So go gentle on the folds.
Piping
Grab that parchment paper with the drawn circles and put it on two baking sheets.
Gently, pipe the macaronnage into the circles.
The Rap: Firmly tap or "wrap" the baking sheets on yourcounter to release trapped air and remove any remaining little peaks from the piping.
Drying
Let stand at room temperature until the tops are dry. That can be 30 minutes in Colorado or at least 2 hours in Texas.
The Test: Touch a shell; it should not stick to your finger and should feel slightly rubbery or have a "crust".
Baking
Preheat to 145°C (approx. 293°F - 300°F).
Some recipes call for the Double-Sheet Method: Stack your tray on top of an empty second baking sheet. This can protect the bottoms from browning too quickly. But again, that ain't me.
Bake for 13 minutes, rotating the pan halfway through for an even rise if needed.
Let them cool completely before filling.
Filling & Storing
For the ganache, cook the raspberries until dehydrated, then pour over the chopped chocolate. I've also tried adding heavy cream for a more realistic, less dense ganache, and it works very well.
Whisk until smooth and chill until firm.
Match the macarons "cookies" with similar companions and fill them with the ganache.
Store the assembled macarons in an airtight container in the fridge or the unassembled "cookies" in the freezer for up to six months.
I messed up the Italian meringue here. Three mistakes: 1) overcooked the syrup, then 2) started whipping the egg whites too late, which made it so that 3) the syrup was getting cold as I poured it into the stand-up mixer. Rookie mistakes. Macarons require attention!
