Our last pressure cooker was very pleased by WMF and we have always been. Therefore, it should be an instrument of WMF again. We have had the 4.5-liter standard pot and the problem that it was for cooking potatoes (80% of the use in the kitchen) really too big, but for the preparation of soups or stews (20% of the stake) to small. Now we have decided to use two pots of 3 liters for potatoes and 6.5 liters for soups and stews and it's perfect. Ultimately, we have spent 40 euros more and received a significant added value, from pressure cookers, we have always been thrilled to the different sizes now the finishing touch to perfection.
