If you like your cookies to be more crunchy, turn off the oven and let them cool down into it after baking.
Remove cookies from the oven, let them cool and place them in a glass container or tin; they will keep fragrant and tasty for a long time.
If you use homemade tahini (toasted sesame seeds blended with a little oil), some whole sesame seeds left will give a yummy extra-crunchiness to your cookies.
You can change orange juice for plant milk or fruit juice of your choice.
