Coarsely grind the peppercorns, toast them a little in a pan without adding any fat, and let them cool down. Spread parchment paper on the long side of a sheet of parchment paper and form a roll from it. Place in the refrigerator for an hour, then cut into slices and serve.
Variant:
Green pepper butter: For this, 3 tablespoons of green peppercorns are roughly chopped, mixed with 250g soft butter and seasoned with salt, pepper and cayenne pepper.
