Best For: Small-batch jams, jellies, honey, hot sauce, herb-and-spice blends, party favors, and wedding-shower jam gifts. Also a popular size for portion-controlled overnight oats and chia-pudding meal prep.
Canning Tip: Wash jars in hot soapy water, then hold them hot (simmering water or oven at 180-200F) until you are ready to fill - hot jars prevent thermal shock when you ladle in hot product. Leave the headspace your recipe calls for (typically 1/4" for jams, 1/2" for fruits and pickles, 1" for low-acid pressure-canned foods).
Note: Lids are single-use for canning; bands are reusable. Forjars sells matching regular-mouth lids and bands separately. Inspect each jar for chips at the rim before processing - a chipped lip will not seal.
