If its the, it sounds like referring to the vegetable pepper which in Finnish is "paprika" I'm sure the article should be optional here
Pepper is round should be accepted. When talking about the ground "spice" that comes in a pepper shaker, it is stupid to refer to multiple granules of the seasoning with "the" when describing it.
You are not referring to Jalapenos or bell peppers.
"Sinappi on mauste" accepts "Mustard is a spice" There is no THE MUSTARD requirement. It obviouslky refers to the sauce in a bottle or jar. What if referred to the actual plant?
You need to CLARIFY and FIX this one!
