For 3 liters:
1. Fill the bottom of the pan with peas, washed several times, rubbing the peas with your hands.
2. Leave overnight in a large (!) amount of salty (!) water. So, once the beans absorb the salt, they won’t seem bland inside.
3. Before cooking, pour in salted (and slightly effervescent) water, washed peas, add salt again (given the salinity of the meat, I would also salt French fries), put on fire with bay leaf and allspice.
