Put the butter, panko flour, herbs, pepper and salt in a bowl. Press or grate garlic. Put on disposable gloves and knead everything with your hands. This works better with the warmth of the hand than with a device. Then spread out 2 - 3 larger pieces of cling film, put enough of the crumbly mass on one half of the film to make rectangular plates with a size of approx. 15 x 7 cm and a thickness of 4 - 5 mm with the flat of your hand can be shaped. Then fold the other half over it, stack all 3 on top of each other, push a solid base under them and put in the freezer for at least 30 minutes. You can later adapt the solidified panels to the required shape. Those that are not required can be stored frozen until they are used again.
