Remember that, my mother was a virtuoso Seb pressure cooker, in the 70s, this pressure cooker evolved since that time, so I picked up recipes of my mother without any problems, I who love to taste the dishes cook traditionally, it changes the way I cook, I have just a small point to make, do not strictly follow the recipes in the book especially on the seasonings "salt, pepper and vinegar" because what cooked to pressure multiplies their aromas.
I even experimented with cooking mussel mussels, great, well cooked and juicy.
