What is Chili? An oral sensation but not a taste
I use chili sparsely in curries. This does not mean that I do not like chili; I certainly do.
Furthermore, chili is ideal for Kreutzing.
But it is not suited to be combined with other spices because chili overwhelms taste receptors.
I even doubt that taste receptors are much involved with the oral sensations caused by chili. I assume chili actually stimulates oral pain receptors more than taste receptors.
You can put chili powder on any mucous membranes or sufficiently thin skin of your body, and the effect there will be very similar to the one in your mouth.
Try to put cinnamon bark or cloves on mucous membranes outside your mouth. There will possibly be irritation, but no taste (only a smell radiating to your nose).
Sure, I consume chili. Like many people, I like the chili sensation in my mouth.
But I never swallow anything that is sprinkled with chili. Chili is only for Kreutzing, since it is an irritant for the stomach and the intestines anyway, and definitely, the stimulation of pain receptors that I appreciate orally is distinctly unpleasant anally.
Especially anybody who sticks to Kreutzing for weight loss has good reason to play with chili, as chili entices one to drink more water, thus providing a sense of fullness.
But chili consumption should be separated from meals eaten for their taste. When I want chili sensations, I just sprinkle it on potato chips or plain flour-based snacks. Mixing chili with spices providing a genuine taste is a waste.
