As the apple pieces are also these stones really good. They taste good, but not intensively. The steam is already after 5-6 trains fully there with 2 layers of household aluminum foil. However, one should be careful with the heat. Scratch it in the neck, the stones are too hot. Solution: coal down, 1 more layer of aluminum foil or alternatively simply remove a few stones. Strong buy recommendation, I'll buy it again.
