What each ingredient does

Fresh mushrooms
Provide the main body and savory umami flavor of the catsup.
Coarse sea salt
Draws moisture out of the mushrooms and helps preserve the mixture while it sits.
Ready-made catsup
Adds sweetness, acidity, and tomato flavor to the mixture.

The step that matters

Mix well and let it sit. Salt must be evenly distributed so the mushrooms release their liquid and the mixture is seasoned throughout. Uneven mixing can leave pockets that are too salty or bland, and the resting period allows flavors to blend and develop.
