Gusa Scotch Bonnet Chilli Mash Only Two Ingredients. Only the Best. Gusa—meaning “Only” in Kinyarwanda—is more than a name. It’s our promise. One variety. Two ingredients. Grown, crafted, and perfected in Rwanda. Pure chilli. Pure flavour. Only the best. What Is Gusa Scotch Bonnet Chilli Mash? Our original Scotch Bonnet Chilli Puree has evolved. Gusa Scotch Bonnet Chilli Mash is its bolder, simpler successor—naturally fermented, made at the source in Rwanda, and crafted from 95% fresh Scotch Bonnet chillies and 5% salt. There is no vinegar, no artificial preservatives, just clean, concentrated heat. People love our products for their simplicity, and we’ve made it even simpler.
