This legume is rich in proteins and healthy nutrients and very common in Italy. It is mostly eaten as a snack during Christmas time or in festivals and fairs.
Wash the lupini beans under running water and leave them to soak in a pot for 24-26 hours. Make sure to change the water in the morning and in the evening.
After soaking, wash the lupini beans again under running water, fill the pot with cold water and put the water to boil.
Prepare another pot with the same amount of water and put it to boil.
Once the water boils, cook for about 2 hours, 2½ hours and, halfway through cooking, transfer the lupini to the other pot and continue to cook for rest of time.
Soaking
After cooking, let the lupini beans cool for 10 minutes.
Then rinse them with running water, and put them back in a pot with cold water.
Keep them soaked for 4-5 days. Changing the water 2-3 times a day: more often they change the water and first they'll become sweeter.
Preparation of the brine
To complete the preparation of the lupins, but also to preserve them until you eat them all, you need to prepare a brine with 60-70 g of salt per liter of water.
Put 1.5 l of water in a pot and bring it to boil.
When the water begins to boil, pour 100 g of salt and stir with a wooden spoon to completely dissolve the salt.
Add the lupins and leave them cooking for a minute.
The lupini beans are finally ready to eat!
Notes
You can store the lupini beans in the fridge, covered by their brine, even for more than a month.
