Honey Truffles

Honey truffles are a rare variety of tuber from Hungary. They taste very different from other truffles and have a strong, cheesy aroma. They're best used in desserts, and are an acquired taste.

I love working with truffles, so when a truffle hunter from Hungary and his friend asked me if I'd contribute to a new book on truffles they were writing by sampling Honey truffles (Mattirolomyces terfezioides) fresh from the earth, shipped direct from Hungary, I agreed (and squealed with joy).

Shipping mushrooms across the pond is no small feat, and it took two tries to get them to me in good shape. With the help of DHL Express, they were able to get me a good half pound of honey truffles in just 3 days. 

I've eaten lots of truffles, but never these. Honey truffles are what I call an alternative truffle (a truffle that can be purchased for less than traditional European species), truffles like Tuber brumale, which I love for it's smoky truffle taste, are another good one. Tuber macrosporum (black garlic truffle) is another I've been dying to try.

Desert Truffles: The Terfeziaceae

As an aside, there's a little breadcrumb trail in the epithet of the Honey Truffle, specifically the word "terfez".The Terfeziaceae I know as desert truffles, a group of truffles native to the Middle East, North Africa, and surrounding area. They're more common than truffles from the genus Tuber, and don't command as high a price. Honey truffles were formerly in the Terfeziaceae, but have been moved into the genus Mattirolomyces.

They're apparently harvested in commercial quantity in Hungary, but not too many other places, and there's no tangible tradition of eating them in Hungary. It seems to me, just like the Matsutake that are graciouly creeping into Minnesotas pine plantations, the honey truffles are setting up shop. For comparison, Tuber brumale is known as an invasive truffle, and can outcompete more valuable species, so It's generally not liked by hunters. I can't speak to that regarding honey truffles. 

Taste and Aroma 

Here's the interesting part. I knew a little of what to expect by contacting some truffle importers I know—honey truffles are going to taste sweet. Not a sweet scent, like you would expect with a truffle, but a literal sweetness. One of my importer friends told me they would taste like saccharin, and they were dead on. 

The aroma is truffle-y, but it's much more than that, and very complex, for better or worse. The first thing I noticed was a bready, yeasty quality I'd describe like an over-proofed batch of rolls. Then, there's an earthy mushroom taste, not exactly truffle-y, distinctly mushroomy. Finally, there's a truffle taste that you'd expect from a truffle, but it's combined, and a bit obscured with all of the other gastro-stimuli. They're strange creatures, really strange. 

I'm an emphatic mycophagist, and go out of my way to find wild mushrooms off the beaten path I think are worthy of sharing with others, but, I have to tell you, honey truffles will not be for everyone. The combination of literal saccharin sweetness with fungal flavor, in addition to the truffle aroma was odd enough that it gave me pause considering the amount of work it was going to take to wrangle half a pound these.

As I expected, honey truffles were a lot more difficult to work with than black or white truffles, which are easy in comparison—with those, you just shave and go. I would say about half the people I fed the honey truffles to didn't care for them, something that I've never had happen with any truffles from the genus Tuber. So, just like with the Amanita amerirubescens I shared a few weeks ago I think the following bears repeating: 

Just because an ingredient is new, doesn't mean it's incredible. 

Cooking 

Cooking is a bit of a misnomer here. Honey truffles, like white truffles, are heat shy, meaning that they don't like to be heated. You can shave them on a warm dish, sure, but you won't be simmering them in anything, and even infusing them in something warm probably won't work.

They're best used, and infused cold. Putting honey truffles with rice, say, as you would black truffles to absorb some of their scent, would be pointless, as after cooking it will disappear. To use them with, say, a risotto of peas or squash (which would be nice) you would shave them on raw, or put a pat of truffle butter raw on the finished product. 

Capturing the aroma 

Honey truffles are a white truffle, and like white (and black) truffles the key for me is in thinking not how I can cook with them, or what I can shave them on, but how to capture their aroma into something. Think of truffles like small orbs that constantly give off gaseous aroma, and your job, is to capture that into another medium to store it.

For example, one of the dishes I made with the honey truffles is a simple crème fraiche sauce with fresh fruit. I ferment some crème fraiche, add eggs whisked with sugar over a double boiler, cool it all, then grate in a bit of truffle and keep it in the fridge. As the sauce rests in the fridge, it absorbs the truffle aroma, ah voila, truffle sauce. 

Another win was maple syrup. Confusingly, the scent of honey truffle didn't like to be captured into oil, which I was hoping would be a way to get past the saccharin kiss of the fresh product.

Grated or simply infusing a few slices into sugar syrup though, was great, and the aroma stays strong and vibrant in the syrup under refrigeration. After the infusion, I discard the truffle or strain it out—something I would never do with black or white truffle. Unlike black truffles, which are dry, honey truffles will get soft and squishy after they're exposed to something like wine or 

Mixing grated honey truffle into butter to make truffle butter was ok too, but the heat shyness came into play again, and it can't be used in cooking. Honey truffle butter must be spread on something warm to melt it, and exposed to the least amount of heat possible in order for the flavor to be noticeable. 

Use Ideas 

• Truffled maple syrup (or another sugar syrup) will be the most economical way to stretch their flavor. 
• Infuse honey truffles into dry white wine as for Maebowle. 
• Grate fresh honey truffles into butter (recipe below) and spread on roasted squash or grilled bread. 
• Croustades or crostini with honey truffle grated or in butter form with pears and blue cheese. 
• Pair with cheesy, salty things, like chevre or gorgonzola. 
• Risotto of peas or squash, preferably with the main ingredient pureed and folded in.
