Grant and I desperately want a beach vacation, as I’m sure most of you reading this do too! So in lieu of that, these key lime pie Macarons are a fun way to feel beachy and get fresh with tropical flavors.

Key Lime Pie
Key lime pie has it all, creaminess, tangy fresh citrus, crunchy crust, vibrant color, and luscious whipped cream. These key lime pie Macarons are bite sized key lime pies that are elegant and so decadently good.
These Macarons are made using the French method. Macarons are finicky and can make even the most skilled baker frustrated. So don’t feel bad if you have a batch or two that don’t come out perfectly. You have to play around to make perfect Macarons. There are days when Macarons can be effected by humidity or an oven that’s running too hot. If you don’t perform your macaronage just right you can be left with hollow or cracked shells or feet that don’t rise.
Check out chamomile and earl grey macs for some extra tips and tricks. But my Mac skills have gotten better since I made those, so I think these key lime pie macs outshine them!

Macaron Tips
I know how to make a mean macaron. And that’s because my macaron mentor is my friend, James Beard finalist and award winning pastry chef, Nathaniel Reid. He is absolutely incredible and makes the best croissants I have ever had in my life. And I am talking on a global scale.
Here are some tips for making foolproof Macarons.
Weigh your ingredients with a kitchen scale! Whenever I bake more adavnced bakes like macarons or French puff pastry or brioche feullitee I weigh my ingredients.
Check your oven temperature. I do this every day since I bake so much. If you blast Macarons with air that’s way too hot you’ll get feet that explode out and are uneven and spread too much. Additionally, the macs will brown too much and be unevenly baked.
Proper macronage is key. However, the state of your egg whites matter as well. If you under-whip the egg whites your macs won’t work. And if you over-whip them then they will crack. The egg whites should be slightly bunching in the whisk. They should be stiff and beaked. If you turned your bowl upside down they should stay put. I have close ups on the video on my Instagram if you want to see the stages of egg whites and macronage.
Use more food coloring than you think. As the mixture whips the color fades. Macarons should be colorful, bright, and vibrant. And always use gel food coloring. That won’t compromise the mixture with too much liquid.
Sift your almond flour and powdered sugar with a fine mesh sieve to get all big pieces out. This will give you super smooth, lump free Macarons.

Pay attention to the stages of your batter during macronage. Watch for batter that you can make a figure 8 with without breaking. And the batter you’re lifting should dissolve back into the batter within 10 seconds. This eliminates little batter bumps when piping. Although, you can easily use a wet finger to correct that after piping.
Pipe evenly so they bake evenly. Use a 1A tip. Use a template if needed.
Do let them dry out after piping. All successful Macarons I’ve always had dry within 15 minutes.
Rotate the Macarons halfway through baking. Cool before filling.

Using Graham crumbs
I incorporate different spices, extracts, and finely ground ingredients like graham crackers or freeze dried fruit into my Macarons. The most important thing to remember is to finely ground that additive. Get creative and use the following recipe as a base. Email me anytime if you need help with your macaron flavor idea and I can give you a recipe guide.
If you desire, decorate these key lime pie macarons with a drizzle of melted white chocolate and a sprinkling of graham crumbs.
