1
Prepare a fire for grilling, if using coals, or set up a gas grill.
-
2
Clean the portabello mushrooms: cut off and discard the dirty stalk bottoms before turning the mushroom upside-down, to prevent loose dirt from falling onto the gills.
-
3
Then, invert the mushroom (cap down), and remove the remaining stalk by cutting off the base of the cap.
-
4
Set aside for later use.
-
5
With a cleaning brush, remove any loose dirt from the cap, and the underside.
-
6
For a final cleaning, wipe the cap with a moistened towel.
-
7
Lay the caps, gills down, on a cutting board.
-
8
Cut through the caps to make cross section slices about 1/3 inch thick.
-
9
Pile slices on a plate or tray.
-
10
Vigorously shake the marinade in the jar, then pour into a large bowl.
-
11
Brush the grill lightly with olive oil.
-
12
With tongs, grab 1 1/2 mushrooms worth of mushroom slices, and immerse briefly into the bowl of marinade.
-
13
Loosen the tongs somewhat and quickly stir/swish the mushrooms around, to let all surfaces of the mushroom get coated.
-
14
Then immediately pull the slices out, allow to drip-drain for a moment over the bowl, and spread, cut surfaces down, onto the grill.
-
15
Note: it is very important to not let the mushrooms sit too long in the marinade?the gills will get soggy, and the end result will be ruined.
-
16
Grill the mushrooms until well browned on one side.
-
17
Baste the upper sides with the marinade, and turn.
-
18
Cook until second side is well grilled.
-
19
(Total cooking time is 4 to 8 minutes, depending on fire temperature, the mushroom slice-thickness, and desired doneness.)
-
20
Remove mushrooms from the grill onto serving plate.
-
21
Repeat with the remaining mushroom slices.Cool briefly, and enjoy!
-
22
Mix all the liquids into a sauce pan, and bring to a high simmer.
-
23

-
24

-
25
Remove from heat, and allow to cool.
-
