The cans are super tight, I suppose soups in the Sport Tashkent and all goes well. The 1,1l can is the all-rounder but di little example for Dresing or similar class. The only downer is the microwaveability: According pressure suitable "but not for cooking" and that is precisely the Prblem. Because the top layer is quickly known by the hot soup in the microwave, is with me even though I have in between stirred always behaved the inner wall of the can at the level of the "water's edge" become purös and inked by the pumpkin soup. The second time I have (although forewarned and every 40 seconds stirred) exactly the same thing happens so that now all the big cans inside have an approximately 1 cm wide rauehn yellow stripes. War mind you no hot curry etc. but pumpkin soup. If I had not expected.
