To make flower jelly, you will need jelly jars, lids, and rings; a large stockpot with a lid, in which to process the filled jars; cheesecloth or a fine mesh strainer; tongs for lifting the hot lids and jars from the boiling water; a funnel; a 2-quart or larger heavy-bottom pan; a candy thermometer; a ladle; and labels.
