I use a steam canner instead of a water bath, not to be confused with a pressure canner which also uses steam. Basicly it looks like an upside down pot. The short lid is on the bottom which you fill with a couple inches of water. There is a short rack which you set your jars on and the larger lid that covers the jars. You bring the little bit of water to boil cover with the lid and when steam starts coming out the hole on the side you start timing.
Esentials---Ball Blue Book of Canning. It's like the Bible of Canning!
Ball or Kerr canning jars of various sizes with rims and lids. Lids have to be replaced everytime, rim and jars are reuseable until they break or rust out.
Jar lifter, cap lifter, funnel--you can buy these as a set.
