Saffron Milkcaps
Saffron milk caps, (formerly known as Lactarius deliciosus) are a crunchy, edible mushroom that have been enjoyed for millennia. Milk caps were one of the first mushrooms to be used in cooking. They were featured in a fresco from the Roman ruins of Herculaneum.
The saffron milk cap is essentially the national mushroom of Spain and the Iberian peninsula. There it’s known as the rovellon, or niscalo. Doing an internet search for rovellones will turn up lot of fun information and saffron milk cap recipes.

Fresco From Herculaneaum
I searched every year and could only come up with one or two, here and there. Finally in the fall of 2013 I hit a great spot in a white pine forest at just the right time. They are great mushrooms, and have a nice crunchy texture, if you can get to them before the bugs!
Habitat
I find them fruiting under Eastern White Pine in Minnesota around August through October. The key to finding them is waiting for the rain during their season.

To me it seems like Saffron milk caps need lots of rain to come out in force.
These often grow buried deep under pine needles, just remember where you see one, more are close by.
Identification
- Bright orange color that stains bright orange when cut
- When bruised, the color fades to green.
- Are found growing with coniferous trees only.
- When cut, the mushrooms will drip an orange latex, or juice.
Species
Originally, saffron milk caps were labeled as L. deliciosus. Recent studies confirmed that North American mushrooms are distinct from European ones.

Note the green staining from handling on these L. salmoneus.
Basically, this means that there’s a group of mushrooms (called the deliciosi, or deliciousus group) that will all cook relatively similar. I’ve eaten 2 or 3 different types, my favorite being Lactarius thyinos, a smaller variety that loves to grow with Norway spruce in Northern Minnesota in autumn. All true saffron milk caps are good to eat.

There’s other species too, including bleeding milkcaps (Lactarius sanguifluus-Europe only). Lactarius salmoneus (North America) and probably others.

Lactarius deterrimus are the most well known imposter. They will grow in the same areas and have a more grey colored cap and gills that are less bright orange.
They finished with a slightly bitter note when I ate them. They’re still in the deliciosus group, and perfectly fine to eat-they’re just not as good.

Cooking
Like the name implies, they’re delicious. You can treat saffron milk caps like any other mushroom, but they do have a texture that’s been called “granular”.
Personally, I think the texture is fine, especially if they’re cooked golden brown.
One of the best traditional ways to enjoy these is niscalos a la plancha: griddled, sprinkled with garlic, parsley and olive oil, similar to French wild mushrooms with garlic and parsley. These make good mushroom pickles and retain a bit of their crunch. They can also be stewed and frozen, but pickling is my favorite method of preservation.

Dried saffron milk caps make great broth.
You can dry these too to make stock or broth, it will taste a bit like chicken stock.
Usually I brush the leaves and needles from these and saute. If they’re dirty I will wash each one quickly by swishing in water, then draining on paper towels until needed.

Milk cap mushrooms are delicious with seafood.
Mucilage
Saffron milk caps cook up similarly to most mushrooms, with a few exceptions.
Some species of Lactarius create mucilage when pickled or stewed, which can work as a natural thickener in sauces and gravies.

Catalan-style Niscalos with sausage is one of my favorite recipes.
If the mushrooms are pickled, they can be a bit slimy when removed-just rinse them off before eating. You can also preserve them in brine, which is traditional in Europe.

On the comparison photo those of the right look suspiciously Lactarius semisanguifluus rather than L. deliciosus. The two are very much alike, but the sap of the former turns wine-red after a few minutes. The sap of L. deliciosus also darkens, but not so fast, and not to such a ruby red. Also the caps of the former have a greenish hue, sometimes distinctly green, even on young ones, whereas L. deliciosus is more orangey-brownish. The gills of both turn green on damage, but those of the former much more intensely. For culinary purposes L. semisanguifluus is equivalent to L. sanguifluus, practically on par with L. deliciosus, so my comment is purely academic 🙂
Hey thanks so much for pointing that out. I wasn’t aware of those. That’s entirely possible, I’ll look through my archive images and see if I can’t update that.
THE FALSE ONES MAY BE BITTER, BUT NOT “POISONOUS”, AS IN RAT-POISON, DEAD. BUT DO THROW OUT THE FALSE ONES.
