I used ghee to make it. After I finished, I found that the biscuits were particularly crisp and the entrance was instant.
Mix the ghee and sugar until the ghee turns pale yellow, then add the egg yolk and continue to stir until uniform.
Add low-gluten flour and mix until uniform
Mix everything and mix well, then knead into a mass. Slice or make any shape you like.
The oven is fired up to 160 degrees. If the biscuit is thinner for 20 minutes, it will be turned over 10 minutes. If it is thick, bake for 30 minutes. I hope you are successful.
