My home-grown harvest of chilli peppers.
Some years ago I wanted to make sambal bajak, an Indonesian chilli condiment.
Therefore I had to cut very small a lot of chilli peppers.
Later on that day my fingers felt like being on fire.
I was unable to sleep because of that and had to put my fingers in cold water.
For more then 3 days I had to deal with this burning feeling.
I never made homemade sambal again.
