Note to self:

1) the left/back side of my oven sucks big time. Temperature rises really really fast, i finally saw it objectively with my oven thermometer.
2) the right side sucks small time, so beware.
3) To increase number of successful macarons, pipe batter in the middle of the tray and place in the middle of the oven, (therefore, try to "undermix" the batter a little since i'm going to have the batter sitting in the piping bag), OR,
4) Pipe as per normal but place tray in vertically and to the right side, and shift tray around as per needed. Eg. When macarons start to puff up, crack, etc. I'll still lose some though... I think i might go the way of point 3. Much less heartbreak and wastage.

Made some lemon ones with my newfound technique. Some got destroyed due to uneven heat but otherwise, i think i can now finally finetune my baking time to achieve a less dry macaron. 14 minutes seems a little too long. Shall try 12-13minutes the next time.

Chocolate shell with dark chocolate mint filling, and the other one is lemon with lemon curd filling. I can't wait to make my green tea with white chocolate ones! The green tea powder is pricey so i've to make sure that i can consistently make okay macarons before using the matcha powder.
