The Honey Jar Spell is one of the oldest forms of bottle spell in the world. There are so many variations that I call it a "spell family." Most of them consist of a jar of sweetener into which you place the personal concerns of the person you want to influence, along with spiritually powerful magical herbs, wrapped in a name-paper or petition packet, and then burning a candle on top of the jar after dressing it with an appropriate conjure oil.
This form of hoodoo spell casting is employed when you want to set up a powerful sweetening spell in a small place and keep it working for as long as you wish. Honey jars are extremely convenient and one reason for their continued popularity is that although they can be worked on an altar like other forms of bottle spell, they can also be literally hidden in plain sight in a kitchen cabinet.
In the oldest version of the Honey Jar spell that I know, there is actually no "honey-jar," just a plain white tea cup saucer or coffee cup saucer in the center of which you burn a candle on the person's name, dressed with hoodoo oils and surrounded by a poured-out ring of pancake syrup or molasses. This old-fashioned method has the disadvantage of eventually drawing flies, but it is extremely easy to work on a short-term basis, say for one to three days. Be careful, though, if the candle burns too hot, it may crack your saucer.
Another early version of the homey jar bottle spell employs a hollowed-out red apple or red onion to hold honey and the name-paper of the person on whom you are working. The apple or onion may be shut up in a tin and a candle burned on the tin's lid -- or it can be placed in the bottom of a flower pot, with a plant grown on top of it to hide the spell. The plant takes the place of candle, but it radiates the intent of the spell just the same. It can be given as a gift to the person on whom you are working, and can spread its sweetness throughout their home.
During the late 19th and early 20th centuries, as packaged sugars, syrups, and sweeteners became available from grocery stores, another variant of this spell that developed employed a box of sugar instead of a jar of honey. By the mid 20th century, the honey-jar version of the spell gradually replaced the old cream-saucer, cored apple, hollowed onion, and sugar box versions.
