Welcome to my Lupini Bean page!
If you are a first-timer surfing the Web for "what are these things", well, don't let the title dismay you-- let it merely instill in you the proper level of caution and respect for the Bean Of the Ancient Mediterranean Scene.

Background:

[First seen in Ancient Egypt; probably first tamed in Greece, 4,000+ years ago:]

"The earliest archaeological reports on lupins are referred to the XII dynasty of Egyptian Pharaohs (over 2 thousand years BC). In their tombs, seeds of Lupinus digitatus Forsk., already domesticated in those times, were discovered... seven seeds of this species were also retrieved in the tombs of this dynasty dated back to the 22nd century BC. They are the most ancient evidence of lupin in the Mediterranean (Zhukovsky, 1929)...

"The beginning of the history of lupin cultivation in the Old World is often associated with the times of the ancient Egyptian civilization (Zhukovsky, 1929; Maisuryan, Atabiekova, 1974; Taranukho, 1980). It is, however, more likely (Kurlovich, 1998) that originally white lupin was introduced into cultivation in ancient Greece where its greatest biodiversity was concentrated and wild-growing forms have been preserved until nowadays... Besides, the Grecian genesis of cultivated lupin is testified by lupin’s Greek name “termis”, that may be translated as “ardent”. Until now, in many countries of the world water-soaked and boiled lupin seeds are sold on markets and in bars as delicacies (like sunflower seeds). Utilization of white lupin was probably the same in ancient Greece."[1]

"These legumes were popular with the Romans and they spread their cultivation throughout the Roman Empire. Today, Lupini are most commonly found in Mediterranean countries and their former colonies, especially in Spain, Portugal, Italy, Brazil, as well as Egypt... Syria, Lebanon, Jordan, Israel, Turkey , Chicago's Little Italy and in New York City's Spanish Harlem, where it is popularly served with beer..." [2]

But remember, the little beasties are poisonous if not properly prepared:

[They contain alkaloids that gotta be soaked out, else they will mess you up:]

"Lupin poisoning affects people that eat incorrectly prepared lupin beans.

"Mediterranean cultures prefer the historic bitter lupin beans with the required toxin-removal by traditional leaching in water preparation methods due to the better flavour that results. Improper preparation of bitter lupini with insufficient soaking allows pharmacologically significant amounts of the anticholinergic alkaloids to remain in the beans, and poisoning symptoms result.

"While the alkaloids found in raw and dried beans are bitter and unpalatable to many, with merely insufficient soaking the level is reduced. Some people like bitter herbs and may mistakenly prepare and eat lupini without enough soaking if they haven't learned of its unique preparation requirements. There are several references in medical literature to poisoning caused by errors in lupini preparation. Dry lupini beans are rarely sold with instructions... [Emphasis mine]

"The Italian and Portuguese tradition is to soak the beans for a week or two in a pillowcase or fabric bag in a stream.

"Symptoms of lupin bean poisoning (from excess alkaloid in cooked food) include dilated unresponsive pupils, confusion, slowed thought and disorientation, flushed face and/or fever, high heart rate and blood pressure, tremors, difficulty with or slurred speech, in-coordination, dizziness, burning dry mouth, stomach pain, and anxiety or "malaise".[3]

Allergic to Peanuts? Be extra cautious:
"... lupin allergy is on the rise and may cause life-threatening anaphylaxis in sensitive individuals. There is some cross-reactivity with peanut allergy, so nut allergy sufferers should exercise extreme caution with lupin-containing food..." [2]

So.
They are a non-trivial dish to prepare.

However, all is not lost if you do not have access to a clear running stream.

I, Chefcuta the Munificent, have put together a very serviceable and tasty recipe for preparing them, out of a bit of info here, and a piece of info there.

First, ya gotta find the beans.
The best locations are where there is a large Italian diaspora, such as Chicago's Little Italy or in the New York City area. Failing that, you can get them online. I (my housemate, actually) got mine from Angelina's Gourmet, on Amazon.com. Excellently, his bottle of dry Lupinis even featured instructions! Which I incorporate into the recipe.

Good dry lupini beans should look very much like oyster crackers-- round, and palest tan. Discard any that are discolored, just in case.

Lupini Bean Taming Preparation Recipe:

  1. Cover 1 cup of beans* with salted water and soak overnight.
    * For each volume of lupinis you want, use 1/3 that amount of the dry beans. So 1 cup will make 3 cups of prepped beans. This amount fits nicely in a used 28-oz marinara/spaghetti sauce jar.

  2. Bring 2 quarts of fresh (i.e. purified) water to a boil. Rinse the beans and add them to the water, and simmer for 3 hours, until the skins are smooth.

  3. Cover beans with salted water in a container, and keep the container in the fridge. Change the water once daily. Repeat this procedure for 14 days (I recommend 2 1/2 weeks). "Mark the start time on your calendar so you don’t forget." [4]


    Batch of lupinis after 1 day of soaking.
    Don't they look innocent?
    But if you look closely, you can see that the water is already yellowish from the alkaloids that have soaked out.

    "It is essential to rinse the beans daily. There are bitter alkaloids in the lupinis that are released in the water over time. You can see the rinse water change each day from a yellow hue to clear after about two weeks. At the two-week mark, taste one of the beans; if it’s still a bit bitter, keep rinsing for a few more days until all the bitterness is gone." [4]

    "When the beans no longer bite back:"

  4. Per quart jar of lupinis (and close enough for a spaghetti sauce jar), put in:

    * 1 Tbsp of Salt
    * ~ 1/4 tsp Whole black peppercorns (or freshly ground black pepper)
    * ~ 1/2 tsp Fresh Parsley (dry flakes will do in a pinch)
    * 1 clove of Garlic (or 1/2 tsp Garlic Powder)
    * 1/4 cup Red Wine Vinegar
    * 2 Tbsp balsamic vinegar
    * Splash of Tamari (optional)
    * and fill the jar the rest of the way up with water, to the top, covering the beans.

  5. After about 9 days of marination, the beans are ready to eat!

Barbara from Dish 'n' That blog goes on to instruct us on how to eat the beans properly:

"Serve the lupinis in a nice bowl with a drizzle of olive oil, salt, if needed, and freshly ground black pepper.


The art of eating lupinis at the table:

Pick up a bean and bite into the skin. Squeeze the bottom of the skin and pop the bean into your mouth. The skins are edible, but too fibrous to really enjoy. The inner bean is succulent and meaty, and the essence of the salt, pepper, olive oil and vinegar come through nicely with every bite.

Practice popping the beans into your mouth — watch for flying projectiles! You wouldn’t want to hit someone across the table at this nice festa, now would you?"[4]

She's not kidding. The little suckers will fly like rockets when you squeeze the skin!

 

And Finally:
Don't eat Grass Peas/Chickling Vetch or Castor Beans, and be careful of Fava Beans if you are Cretan.

"The following legumes... are toxic even when cooked. There are no known methods of preventing these toxicities other than avoiding consumption of the offending legume.

"Grass pea, also known as chickling vetch – cause of lathyrism paralysis, and subject of Goya's painting 'Thanks to the Grass Pea', of starving and paralyzed peasants in the Spanish Civil War. Grass pea is now beginning to be sold in west coast North American health food stores along with spelt/farro as an artisanally produced, trendy ancient protein source. Do not eat this as a major part of your diet. It resembles a tiny flattened chick pea a little larger than a lentil, and is a great source of protein and neurotoxin. While the neurotoxic effects may not be obvious unless the pea is eaten as a large part of the diet for several months, it is not clear whether the effects are cumulative at lower consumption levels.

"Fava beans – rarely toxic to people, especially males, of Cretan origin, susceptible to favism, a rare genetic form of fatal hemolytic anemia.

"The castor bean – is not a legume, but Ricinus communis, a member of the spurge family, the Euphorbiaceae. It is confused with legumes because of its common name. It is never sold for food as its protein is very toxic, but it is a source of castor oil for industrial use."[5]
