I've never made macarons before. Not to get them confused with macaroons, which are the American version made with coconut. These however, were fantastic. They're made with almond flour or meal (recipe here). And apparently they're really hard. Well- I didn't find them really hard to make yummy, but I did find it difficult to make them pretty. These are delicious- chewy, sweet, and almond. I do think that you have to think carefully about the flavors and filling, because I can easily imagine this becoming sickeningly sweet and therefore not as yummy.
Take 1: Plain almond macarons with an orange dark chocolate ganache filling. Okay, except bumpy and cracked.
Take 2, part 1: Green tea macarons with plain dark chocolate ganache filling. Better, but not as much rise, and still many were cracked. But these are definitely my favorite- not too sweet, and I love the green tea/chocolate/almond combination.
Take 2, part 2: cinnamon apple macarons with plain dark chocolate ganache filling. Almost complete failure. Some of them burned, almost all of them cracked- if not while baking, then while trying to remove them from the sheet. And they were a little on the sweet side.
Someone made a bacon macaron with cream cheese/cheddar filling. I don't know how I feel about that, because the cookie base is mostly egg whites and sugar. But it's intriguing. The one I really really want to try is a pumpkin pie macaron, but the grocery store was out of pumpkin. (I KNOW, right??)
