I got these at the Marché d'Aligre today.
You might be pondering the same question I did the first time I saw them: What the hell are they?
Underneath all that somewhat disarming browny-green organic matter you'll find fresh noisettes, otherwise known as hazelnuts.
If you've never tried a fresh hazelnut, you must. Like fresh dates and almonds, they barely resemble their traditionally consumed dried counterparts in flavor or texture. They're still crunchy, but more akin to a carrot's crunch than a peanut's.
I've wanted to try these ever since they started appearing at produce markets around town a few weeks ago, along with the très autumnal chestnuts and chanterelles, but the 10-euro-a-kilo pricetag always put this notorious tightwad off. At Marche d'Aligre, they're only 4 euro a kilo. I like that price better.
