After 14 times of trying hard, I finally success in baking my own macarons. HAHAHA.
As silly as it seems, after the span of few years I tried to re-create recipes from Youtube, and failed. Finally successful when I went to baking class. It's not about the recipe, in fact they are pretty similar with the recipes I saw from Youtube, but I learnt some techniques from the class. The cookie should be dry enough before it's baked. This is the main problem that I had in my earlier attempts, also, different trials have different problems. So, glad, I finally found the secret of baking one. Mind you, it's really seriously finicky cookies, and you need to spent a lot of effort in making one, so I think 2 to 3 Dollars per piece is really because it's hard to make. The funny thing is, I don't really like this cookie because it's too sweet, it just looks cute (especially in pastel colors, or cartoony shapes).
Every time I failed in doing something, in the end I want to think that I will be able to do it, I just need to learn from the mistakes and try again. :)
