I am not from India. But I really like to taste different kind of spicy food. It feels like a journey to the food or to the road of taste.
We all got different choice in our life. But as we are from different culture and grow up eating different kind of food. So it does not work equally to everyone. You may not like the taste of spice. It is okey. If you would taste from your childhood, then you would not taste other food without spice.
India and countries around India have a long history of spice. Culturally we use spice in different thing, not just in food. So we used to its smell and taste. That is the other reason we feel joy consuming spicy food.
The taste of a food works scientifically in our brainSpice also have many health benefits. So we take them not only for taste but also for health issues. And yes spice make the food more durable to be eatable for long. The culture grows as because of the influences of the environment.
and body. We like those food in our comfort zone and enjoy that. My mother do not eat burger. The taste of cheese does not attracts her. As because she did not eat cheese from her childhood, it feels like smelly to her. People who do not love the taste of spice have the same thing happened to them as my mother.
But I really get used to spice. Without spice I could not enjoy the food. I take extra chilly or paprika on my food when I go outside. It is because it is my comfort zone of taste. And it is also happened to most of the Indians I think. They will never enjoy other food which do not have certain level of hot or spice. I also saw people to carry their own chilly to restaurants. This is how the taste works on us.
We raised up in different culture and consume different foods. It may seems normal to one corner of the globe and in other part it may seems very abnormal. Which is normal phenomena.
Enjoy your food and have a nice day.
