Why to grind pepper late
Black pepper's bite comes from piperine. Its fragrance comes from volatile oils inside the peppercorn. Grinding breaks the cells open and the oils start escaping. Pre-ground pepper has often sat for months, so it smells much weaker.
Grind late
Pepper added at the start of a long simmer loses much of its fragrance to the steam. Grind it near the end or over the plate, so the aroma reaches your nose, not the vent hood. Coarse grinds give sharper bites. Fine ones blend in.
