    Lactarius Indigo Vinaigrette

    I went through a phase where whenever I found Lactarius indigo growing I tried to come up with preparations that would keep their blue color. One of the more interesting indigo milk cap recipes is a blue mushroom vinaigrette. You can use it on a salad, or as a condiment for poultry and fish.

    Lactarius Indigo Vinaigrette

    It's not the type of vinaigrette you're going to throw on a salad, since you won't be able to enjoy the color, rather, it's  meant for dressing something like a piece of fish or chicken, (poached or grilled would be great).

    Keeping the color is key to making this look attractive. As I talked about in my recipe for preserving lactarius in oil, keeping the color of the mushrooms is done by exposing them to moist heat in combination with vinegar or citric acid. For our vinaigrette recipe, I found that allowing the mushrooms to macerate with the vinegar without any heat keeps the attractive color the best.

    Does this mean that the mushrooms are raw and you have to be worried about eating them? Not at all. I've never had a problem eating lactarius indigo and the maceration process, although it doesn't involve heat still "cooks" the mushrooms and starts to break them down with the exposure to salt and vinegar.

    It only takes a couple mushrooms to make a batch, and some that may have some damage will be fine, just make sure they're fresh, crisp, and most importantly still giving off their deep blue color when cut.

    Lactarius Indigo Vinaigrette

    Prep Time15 mins
    Cook Time5 mins
    Course: Appetizer, Salad
    Cuisine: American
    Keyword: Lactarius indigo, Mushroom Vinaigrette, Vinaigrette
    Author: Alan Bergo

    Ingredients

    • 1 cup vegetable broth preferably homemade
    • 3 cups chopped fresh lactarius indigo mushrooms
    • ⅓ cup mild olive oil
    • ⅓ cup champagne vinegar
    • Small clove of garlic minced
    • 1 tablespoon shallot diced ¼ inch
    • 1 tablespoon chopped fresh thyme
    • 1 teaspoon kosher salt plus more to taste
    • ¼ teaspoon ground white pepper optional

    Instructions

    • In a small bowl, combine the shallot and garlic with the salt and pepper then allow to macerate for 15-20 minutes. Add the mushrooms, vinegar and thyme, and place the mixture in a food processor.
    • Process the mixture, drizzling in some of the vegetable broth until you get a smooth puree. You may not need all of it.
    • Finally, drizzle in the oil, still processing all the while.
    • When all the oil has been added, double check the seasoning and adjust as needed, then transfer to an airtight container (a mason jar works great for vinaigrettes) and reserve until needed.

    Notes

    Spoon it on a piece of grilled chicken, pork, or fish. You can also keep it in the fridge to show your friends as a conversation piece, so they can see just how much of a mushroom loving weirdo you are.

      You think that could help Blewits (Clitocybe nuda) keep their color as well?
      A neighbor's yard-waste compost pile keeps giving me 2-3 pounds of the mushroom a week, but I get so disappointed when the great smell and color disappear when I cook and what's left could pass for store mushrooms.

        I don't think blewits will work for this. Not enough blue color compared to L. Indigo.

      Am I missing in the directions where to incorporate the vegetable broth?

        A typo. Drizzle in the broth with the mushrooms while you blend them to help get it smooth, you may not need all of it. Thanks for letting me know, I need to update this with weight measurements too. A

          Perfect way to use these beauties! It's mild yet flavorful. A very tasty vinaigrette. I can't wait to use it over some of my dishes! Thanks for this recipe 🙂 I hope you don't mind if I share this to my mushroom group. These are in full season right now in Ontario.

      I am wondering if this would freeze (and thaw) well. Has anyone tried?

        It'll freeze just fine.
