I made the Jalapeno Mushrooms again the other day because I still had all the ingredients, except the mushrooms. I picked up a package of the large ones at the grocery store. (The first time I made them I had used smaller mushrooms because that's all there were at the store that day, but the larger ones are best.) The Mushroom recipe reminded me of a recipe I found many years ago, Jalapeno Popper Spread, which when I make it someone always asks for the recipe. That recipe can be found under Appetizers in the Recipes #1 page of this blog, if you want to try it.
Even though I thought the Mushrooms were really good, the cream cheese seemed a little over-powering so as per the Popper Spread, I added mayonnaise (about 1/4 c.) and Parmesan cheese (approx. 3 T.) to the ingredients. I also used canned jalapeños (about 1/4 c., I think). This made the Mushroom recipe superb, IMHO!
Therefore, I am revising the recipe to include these ingredients from now on. I highly recommend this! Just in time to try a new appetizer for the holidays!
