Much excitement among my friends about this method. Connie, whose book comes out in a few weeks, had this to say on another forum:
Chanterelle Blanching-
This is pleasing and a tad embarrassing all at once. After all these years of
close chef contact and the mushroom biz, I thought I had a handle on just about
every basic chanterelle cooking technique. Wrong! A dear friend sent a post from
a wine blog about a chanterelle cooking method. The writer had been taught in a
French school to blanch the chanterelles in boiling water before sauting. The
instruction was to blanch the whole chanterelles in rapidly boiling water for
20 seconds, remove, drain, pat with a towel, slice if needed, and then proceed
to saut them until caramelized. The result are chanterelles that have actually
shed much of their excess moisture during the blanching process. The
post-blanching chanterelles saut nicely without bleeding liquid into the saut
pan. I knew that butter poaching has the same effect, but didn't realize that
the poaching was actually removing excess mushroom moisture.
After cross examining a French friend in the French wild mushroom trade, he
confirmed this. They have a lively business in producing little containers of
pre-cooked frozen wild mushrooms. They do this on a large scale, blanching,
draining and sauting in oil, then freezing the mushrooms. He states that this
works very well indeed.
This makes sense also in the case of a master pickle maker that has done some
custom mushroom pickling for me. Our first efforts at heat pickling mushrooms
resulted in a dilute flavor. In our next effort we pre-blanched the mushrooms in
a brine. The result was superior concentrated flavored pickles.
I REALLY wish that I could add this to the technique section on my new book. Too
late- it's already in boxes at the printer. Drat!
