Ajvar with Roasted Peppers Granny's Secret 550g is made from chopped roasted red peppers, a little oil vinegar, and salt. The recipe uses 11 peppers in each jar. The peppers are roasted and dipped in cold water and blanched. Then they are sent to vacuum cookers and are cooked at mild temperatures for hours. The slow, low-temperature process is key for keeping the essence in tact.
