Llajua or llajwa is a Bolivian chili sauce prepared from locotos hot chili peppers and tomatoes; sometimes onions are added to the mix. One or two seasoning herbs could be added, depending on the region and taste: quillquiña in Cochabamba and wakataya in the Altiplano and other valleys of Bolivia. Llajua is also made and consumed in Northwest Argentina due to its close proximity to Bolivia. It is preferably prepared on a grinding stone called a batán, which can be found in most Bolivian households of Cochabamba and the Altiplano. In the absence of a batan, it can be prepared in a blender.
