FAQ’s
Choosing the best mushrooms
When buying whole loose mushrooms, choose the ones that are look fresh without dark spots or molded look. They should feel dry to touch and always firm. If they are mushy or flimsy or slippery, do not buy them. Mushrooms should always be stored in a refrigerator and kept sealed in it’s original packaging to preserve it’s freshness. If you are buying them loose without packaging always store in a paper bag (I just use the brown lunch bags).
How to clean mushrooms
Many recipes say to wipe whole mushrooms clean with a damp paper towel or cloth only. But I like to rinse mine first and then dry them down with a kitchen towel or paper towel. There are also special brushes to clean mushroom if you prefer that fancy way. But who has time to brush every single mushroom? I personally chose the fastest way out always 🙂
Which are the best Mushrooms to use for Garlic Butter Mushrooms?
You can any type of mushrooms you like. I prefer using button mushrooms (whole) while roasting or baking them in the oven. There are different kinds of mushrooms and here are a few commonly used mushrooms to get you familiar with what to choose.
- White Button Mushrooms: This is an immature version of mushrooms and has a very mild in flavor which makes it more versatile. Very commonly used in soups, pizza, stews and salads.
- Portobello Mushrooms: They are large in size, about the palm of your hand. Portobello mushrooms are dense in texture and have a rich taste. They’re perfect for grilling and stuffing. If you haven’t tried my Caprese Portobello Mushroom recipe, you should!
- Cremini Mushrooms: Which I used for this recipe, are young Portobello mushrooms. They are labeled as baby Portobello Or Baby Bella mushrooms in most stores. These mushrooms are basically more matured than white mushrooms and have a bolder flavors. They are great with stews, for grilling/roasting and sautéed dishes.
Storing leftover Garlic Butter Mushrooms
Leftover Garlic Butter Mushrooms can be refrigerated in an airtight container and consumed within 3-5 days. Reheat through in the oven until warmed.
