Corn
Make careful selection of tender, juicy sweet corn, at best stage for table use. Can as soon as possible after gathering. Remove husks and silk; blanch tender ears 5 minutes, older ears 10 minutes. Cold dip and cut from cob but not too close. Pack at once into hot sterilized jars. As corn swells during sterilization, leave space of 1 inch at top. Add salt and cover with boiling water. Be sure that water penetrates through corn to the bottom of jar. Loosely seal and sterilize three hours in boiling water. Remove when time is up, tighten covers, invert to test seal and cool.
Jams
Jams are usually made with small fruits or with chopped large fruits. Cook slowly with an equal weight of sugar until thick; put into sterilized tumblers or jars and seal.
