I have a love-hate relationship with macarons. I love it because it is so beautiful and yummy, but I also hate it because it is so finicky to make. It took me more than 10 times to get it right and give me consistent results. If you ask 10 bakers what is the most challenging or difficult thing to bake, I bet 9 of them would say: macaron. It is made up of 3 simple ingredients: almond flour, egg white and sugar. But it is hard to conquer. Cracked tops, no "feet", hollow shells...and there are so many factors affecting the outcome, like quality of egg white, almond flour, humidity of the kitchen, over beating or under beating, over folding or under folding, baking temperature...Long story short, just before declaring defeat, my son said, "Don't quit, mom! They are so good." I said, "Ok, one last try."
