To begin with, preheat your oven to 350° and lay a/some baking sheet(s) on your tray.
Mix the flour, baking soda, baking powder and salt in a small bowl. Set it aside after you have done it.
Take another bowl and start mixing the sugar, butter, lemon juice, egg, and vanilla essence.
Gradually start mixing everything together by putting the dry ingredients into the wet ingredients slowly.
Take the finished batter and roll it into balls. Place it adjacently on the baking sheet, leaving 1 inch/3 centimetres between each ball. After that, sprinkle sugar generously on top of the balls.
Pop these cuties in the oven for a good 8-10 minutes. Finally, (finally!!) take 'em out and let them be in the baking sheet for 2 minutes. After that, yep, you guessed it, ENJOY!
