Several years ago the Mushroom Council started a campaign to encourage mixing mushrooms with ground beef, turkey, or lamb to create a "Blended Burger".The idea is to mix the ground meat of your choice with chopped mushrooms in the ratio of your choice. The suggested ratio is 1/4 chopped mushrooms to 3/4 meat. The mushrooms can be roasted or sauteed before adding to the mix.The "movement" gained celebrity status when the James Beard Foundation held a chef's competition for the best "Blended Burger". The entries were amped up and fun - black garlic aioli or charred ramp mayo, anyone? The recipes are online if you are looking for inspiration. The blended burger is a great idea! It has the benefit of additional savory umami flavor. The burgers are juicier and the amount of meat consumed is reduced. Mushrooms are an earth-friendly, renewable crop. They need very little space to grow and very little water. I have well-sourced information that this recipe works perfectly as an Impossible Burger/Slider too. That should cover everyone's options!
