I found dried lupini beans in "European" grocery in Seattle. I bought them, thinking they were just a big handsome bean for soup. The cashier warned me that they are actually a sort of a cocktail snack that takes repeated soakings, boilings, and weeks to prepare. She suggested a google search for a recipe.
I googled and found a single vague recipe - 20 minute boil, followed by 5 days of once or twice a day rinsing and changing lightly salted water, thus extracting the intense bitterness.
Seven days later I have beans that are large, handsome, no longer bitter, lightly salty, and crisp as a raw carrot. I think this is probably not the desired texture. Anyone know where to go from here?
