Flour macarons are a great alternative to almond macarons.
You can choose it for your nut allergy or for your economic benefit.
This is purely a matter of personal taste.
Yes, of course, it's less savory.
If you choose to fill it with different flavors, it will be a better macaron.

* Be sure to check the note below.

[Flour macaron shells]
70 g egg whites (from 2 large eggs)
45 g (1/4 cup minus 1 tsp)granulated sugar
110 g (1 cup) powdered sugar
70 g (1/2 cup plus 1 Tbsp) allpurpose flour

*NOTE
1) Flour macaron batter tends to become thin quickly.
2) Therefore, do not overfold the batter,
but fold it slowly while observing the condition of the batter.
3) I used a small electric oven.(45 Liter)
In the case of a gas oven, increase the baking time.
4) It can vary from oven to oven, so adjust the temperature and time!!!
5) Bake one tray at a time.
6) Fill the cream and mature the macaroon in the fridge overnight.
