Batch cooking involves preparing ingredients and basics by cutting, processing and portioning. These can then be combined later to prepare different dishes . This allows flexibility in putting together meals without having to cook from scratch each time, saves time washing up (you only have to clean the cutting board or blender once). The big advantage for us is: cooking with fresh ingredients, frying the garlic in the pan, smelling the aroma of freshly cooked food in the kitchen every day and yet preparing the basics once to save time.

1. Time saving: Batch cooking saves time because you don't have to cook for a long time every day. Prepare once, eat several times! You also save yourself the daily thought of "what are we eating today?"
2. Freshness: Meals are freshly prepared to preserve their flavor and nutrients. No compromise on quality!
3. Feeling of real cooking: You experience the cooking process despite preparing in advance. Balancing flavors, adding spices and being creative is still there.
4. Less food waste : With batch cooking, recipes are coordinated in such a way that the ingredients complement each other and are used up.
