The French have the best word for thick, velvety soups: velouté. Even the word is velvety. And we have been enjoying a velouté of white beans since the Carnivore picked up the recipe at a truffle market, where he got this beauty. They call truffles black diamonds for a reason.
It was velouté de haricots lingot et truffe–a thick, velvety white bean soup with truffles. OMG. Lingots are ingots, like the bars of gold, but in this case they refer to the special white beans grown just west of Carcassonne and used for cassoulet.

Here’s the recipe, handed out at the market. We didn’t follow it precisely because the box of lingots was 500g and we weren’t going to keep 100g sitting around lonely like that. Also, it calls for a 30g truffle, and ours had been whittled down to 13g. I tell you what, it was still fantastic.
We made it again, with rehydrated dried shiitake mushrooms–yummy. A good alternative when truffles aren’t available.

Like so many French recipes, you have to make it over two days. The night before, soak 400 g (14 oz.) of beans (or more!). Separately, chop up your truffle and infuse it in 10 cl (about 3.5 fluid oz.) of heavy cream. (You might want to keep a few shavings on the side for garnish.) If you don’t have a truffle, use about a half a cup of shiitake mushrooms that you soaked and put through the blender or food processor to get the effect of shavings.
Next day, cook the beans. Start with cold water and cook them for two hours.
Peel and mince half an onion and one carrot (I set out two carrots for the Carnivore to use and he fell for it. And the soup was divine despite double the vegetables.)
When the beans are done, drain them and rinse with fresh water.
In a casserole, heat a tablespoon of olive oil and cook the carrots and onion to soften them but not brown them. Then add the beans and half a liter (17 fluid oz. or just over a cup) of chicken stock. Bring to a boil and then drop the heat to low. Cook for 30 minutes.
Remove from the heat and add the truffle cream. Salt and pepper to taste. Use a soup mixer to turn it into a creamy, velvety, homogenous texture. If you use a blender, let the soup cool before blending–for safety–and then reheat.

Serve with a few shavings of truffle, if you have any left.

We have a mushroom hater in the house who devoured this because the mushrooms were reduced to tiny bits (we didn’t mention them, either). If you aren’t a fan of mushrooms, I guess you can go without, but since they’re so tiny here, you don’t notice them–you just get the depth of flavor that they add.
Sounds divine! Will make it as soon as we get back home from hot Thailand.
Did a cooking class btw. So Tom ka kai is also on the soup list from now on.

Ooooh! That sounds great. Cooking classes are among the very best souvenirs–they take no space in your luggage and are very useful when you get home.

I could taste your soup as I was reading your post, and I’m still salivating!! I think some truffle oil would be quite a nice addition if made with shiitake mushrooms. I’ve got some white beans in the pantry, will have to give this a try!!

Oh, yes, a drizzle of olive oil (with or without truffles) adds mouth feel.

Is it raining in your neck of the woods? We FINALLY have rain, and, yes, it’s a perfect day for soup. I hope you like it.

No rain today so far, but a big storm yesterday afternoon. I just got back from 6km hike and it’s cold outside though, even with windproof jacket over winter running gear.

So we did have some rain today, not much, and some thunder and lightning.
The soup is finished and we had some for dinner. I thought it was a nice interesting (and vegetarian if you used veggie stock) alternative to pea’n’ham soup. I reckon I could easily have ‘hidden’ more veggies in it — more carrots, maybe some celeriac. I added garlic granules along with the salt and pepper. It makes lots which is great, so I’ve got plenty in the freezer too. I cooked up a whole kilo of beans and put half aside, so I forsee Tuscan style sage and garlic bean dip in my future.

So glad you liked it! I usually put extra vegetables into dishes, but as this was an Official Truffle Recipe, I passed it on as is.
Sage and garlic bean dip sounds divine. Going to make that.

If I’d been making it with truffles I’ve no doubt I would not have tampered with it, and especially not added garlic. But it’s such a good combo with shiitake, and I felt like it needed it.

It sounds and looks delicious. Never thought to add mushrooms to beans. I’ll try it as I cook beans quite often, mostly pinto though. And I use the crockpot.

Crockpots are great. I don’t have one—very few appliances. The mushrooms just add depth—there are no squishy pieces.

I do wish we had truffles. The soup sounds perfect. I guess a dribble of truffle oil will have to do. Are the white beans the same as cannelloni beans….I have those.

I found conflicting information about the beans. It seemed that cannellini and lingots are very similar, but then I found on cooksinfo.com that navy beans and white kidney beans are the equivalents. However, that article talks about the Lingots du Pays Ariégeois, when everybody here knows that lingots come from Lauragais, the region between Castelnaudary and Toulouse (Ariége is to the south, in the Pyrénnées foothills). I think you would do fine with cannellini.

Why did you soak the shitake mushrooms you used in this soup and what did you soak them in? Were they fresh or dried? Your soup sounds delicious and I would love to give it a try! Thank you for so generously sharing your recipe.

They were dried, so it would have been hard to chop them down in the blender. If you use fresh, you don’t need to soak them.
