Technique: Raw Pack
Raw packing (or cold packing) is a canning and food preservation technique where raw fruit is placed into jars, then cover with boiling hot sugar syrup, juice or water. Raw packing eliminates any prior cooking of the fruit. To properly raw pack t is necessary to leave a head space (about 1/8 - 1/2 inch) between the lid and the top of food or liquid to allow for fruit expansion and the bubbling of the liquid. If jars are too full the contents may overflow during processing.
