Filling the jars

As soon as manufacture is completed and a successful gelling test has been performed, the jars that have been prepared must be filled with the hot mixture. Any foam produced during boiling is removed with a skimmer before the jars are filled. 

The jars must be cleaned carefully and are filled up to the brim, if possible, and then sealed. Twist-off lids are generally used. New lids should always be used, as used lids do not usually guarantee a completely tight seal. 

As soon as they have been filled, the jars are turned upside down. In this way the lid is sterilized with the hot fruit mixture. The lids can also be sterilized beforehand with alcohol or in an oven. 

Products made with agar agar take up to 2 days to gel. The jars should not be moved during this time. 

In jams with more than 65% dry matter content, the sugar may crystallize out as a result of cold. This occurs especially when honey has been used as the sweetener.

The more solid materials are transferred to tins or jars by hand, using an ice-spoon. The more liquid materials are transferred to the jars or tins by opening the tap of the round-bottomed flask. This flask can be heated if necessary when filling the jars. 

Shortly after closing the twist-off lids or sealing the tins, at least on the same day of filling, the jars or tins are sterilized by autoclaving for 30 min at I20°C, whilst maintaining a pressure of 2 bar. The cooling time is 30 min. A disadvantage of the...

Pack three 1-pint canning jars with the okra vertical and alternating stems and tips. Put a halved garlic clove in each jar as well. In a nonreactive metal pot, bring the liquids to a boil. Add the salt and spices. Allow to steep for 20 minutes. Fill the jars with the liquid to within 1 inch of the rims. Wipe the rims and put on the lids. Put the glass jars on a rack in a deep kettle and cover with hot water by 2 inches. Bring to a boil, cover, and boil for 10 minutes. Remove the jars from the bath and leave to cool. Let the pickles mellow for 2 weeks minimum before tasting. Best at 1 month.

In a tall glass jar, or bottle, put a solution of indigo, not much more than half-filling the jar. Invert a bottle or flask of chlorine gas over the mouth of the jar, the gas being about 2.5 times as heavy as air will pour out like water. Close the mouth of the bottle or jar with a cork or bung and shake. All trace of colour will almost immediately disappear.

Plunge tlie jar full of air, mouth downwards, quickly but steadily into the water. Tlie water rises but a short distance owing to the air. Do tlie same with the one full of ammonia gas the water rushes up and fills the, jar, owing to the great solubility of the gas in watw, which dissolves at 0° O. 1050 times its volume of gas. It is best to cover the mouth of each jar with a greased plate, and remove it under water.
