Combine the butter, peppercorns, honey, and salt to taste in a small bowl. Cover and refrigerate for at least 30 minutes and up to 1 day to allow the flavors to meld. Remove from the refrigerator 15 minutes before serving.
This sauce is slightly magical. The texture cloaks pasta much like a traditional meat sauce does, and the flavors are deep and rich, but it’s actually vegan!
