The japones pepper (a.k.a. santaka pepper or Japanese pepper) is an Asian spice staple often used in Japanese and Chinese cuisines, especially Szechuan and Hunan dishes. They are “fire bringers” – providing heat to a recipe without a lot of flavor complexity that could potentially muddle the overall flavor balance of a dish. The japones pepper’s slim form and moderately high heat also allow the chili to be very useful for liquid infusions, like hot pepper oils and vodkas. They share a similar heat profile to chile de àrbol– to which they are often compared.
