What are the differences between cochineal, lac, and shellac, insects we actually eat every day? Is it true that they are found in large quantities in red foods and lipstick? Are they dangerous? Why are they used?

Kaldi Sambar Label history

How can you best use Kaldi's sambal? Why do they use chili peppers native to Central and South America? I investigated this along with its history and food culture in Indonesia.
