I've got a local guy that provides me all my hot sauce. I used to buy from supermarkets but I've become convinced that sourcing everything I eat locally is the way to go.

Anyway I only need to order from him like once per year because he sends me about 1l of this carolina reaper sauce that is so potent it only takes a few drops.

Growing chillies easily becomes its own rabbit-hole. I grow between 30-40 different varieties, which, depending on where you live, can be an interesting and near year-long venture.
