Tips And Tricks:

  1. The instructions seem rather vague. Not sure what you mean “prepare broth”. I’d be interested in trying this recipe but it’s confusing. Can you clarify/enhance the instructions?

    1. Thanks for reading Kathy.

      We tend to put the longer description up in the recipe post, and then just put a quick description down in the recipe card (that’s the thing at the end of the recipe that is a short version of the recipe).

      So for the prepare broth step here’s what we said in the post:

      “In a pot, bring broth and a cup of water to a boil, add in your mushrooms, season with salt to taste and simmer until cooked (approx. 15 min)”

      But I take your point, that the recipe card at the bottom isn’t very detailed. Would it be make it more user friendly if we added more details down in the recipe card also?

      Since some people like to print the recipe card out we try hard to keep it on one page, but I can definitely see where it could be more helpful to add more detail down there.

      Thanks again for reading, and definitely let us know what would be more helpful, we will try to incorporate your ideas.

      1. I plan to try this recipe as well…mentions adding garlic to sauted oinions, but doesn’t list garlic in ingredients…and you cook the peas with the noodles?
        Thanks
        Lois

        1. Thanks for reading Lois.

          We forgot to include 1-2 cloves of chopped garlic in the ingredients section. I’ve added it now. And yes you can cook the frozen peas in with the noodles to save a dish to clean up. You just want to make sure to put the peas in at the end when the pasta is almost ready. The peas only need to cook 2-3 minutes.

  2. Made this tonight and we loved it! I doubled the mushrooms because i needed to use them up but followed recipe exactly. Will definately make it again!
