Do you grind your own pepper?
Back in the day, serious cooks had two pepper grinders; one for black pepper, one for white pepper. White was for when black flecks were not wanted, or to tone down the spiciness.
Now, there are at least 9 spices either sold as peppercorns or in peppercorn blends. Not to mention chili peppers; a whole 'nother topic.
The most common blend apparently consists of green, black, white, and red peppercorns. FWIG, all 4 start out as berries of the same black pepper plant (
piper nigrum). Green peppercorns are the unripe berries. Black peppercorns are picked green, but fermented before drying. White pepper is made by soaking black pepper to remove the outer pulp. Red peppercorns are the dried, ripe berries. Each has a distinct flavor and spiciness.
Some peppercorn blends add coriander. It sort of looks like white pepper, but is the seed of the cilantro plant.
I have also seen Jamaican allspice sold as Jamaican peppercorns or added to blends. Whole allspice resembles black peppercorns, but tastes like a mix of cloves, cinnamon, and nutmeg.
If I want coriander or allspice, I can add them.
Pink peppercorns and Brazilian peppercorns are unrelated spices that are somewhat similar. Sold separately or might show up in cheaper blends? I would try to avoid them.
Then there is szechuan peppercorn , an unrelated, but possibly interesting spice. I have no experience.
I recently bought a third pepper grinder for a blend of green, black, white, and red. Got the peppercorns via Amazon after reading reviews. Satisfied. Sucker?
