In many typical bolivian eateries you will see a bowl of red (sometimes green) sauce on the table served along side the other condiments.This is the spicey sauce known as "Llajua" (or llajwa).  If there is not a bowl on the table then you will probably be able to request some as they will probably most likely have some ready made in the kitchen. In Bolivia Llajua is as common as ketchup in the many western countries and is used to add to kick to soups and main courses by many people.
