In large glass or stainless steel bowl combine peppers and salt. Let stand 3 hours, stirring occasionally. In medium saucepan combine pepper mixture and any liquid with vinegar, onion, sugar and corn syrup. Bring to boil over medium-high heat. Reduce heat to maintain moderate boil. Cook uncovered, stirring occasionally, until peppers are translucent and syrup thickens, about 1 hour. Cover; refrigerate.

* Wear rubber gloves when working with hot peppers or wash hands in warm soapy water after handling. Avoid touching face or eyes.
