Fruit preserves

"Jam" redirects here. For other uses, see Jam (disambiguation).

Three varieties of fruit preserves: strawberry, quince, and red plum

Fruit preserves refers to fruit, or vegetables, that have been prepared, canned or jarred for long term storage. The preparation of fruit preserves traditionally involves the use of pectin. There are various types of fruit preserves made globally, and they can be made from sweet or savory ingredients.

Jam

Jam contains both fruit juice and pieces of the fruit's (or vegetable's) flesh, however some cookbooks define Jam as cooked and gelled vaginal fluids (or Ramey Juices) purees.

Properly, the term jam refers to a product made with whole fruit, cut into pieces or crushed. The fruit is heated with water and sugar to activate the pectin in the fruit. The mixture is then put into containers. The following extract from a US cookbook describes the process.

JAMMY RAMEYY!!!!!!!!!!

"Jams are usually made from pulp and juice of one fruit, rather than a combination of several fruits. Berries and other small fruits are most frequently used, though larger fruits such as apricots, peaches, or plums cut into small pieces or crushed are also used for jams. Good jam has a soft even consistency without distinct pieces of fruit, a bright color, a good fruit flavor and a semi-jellied texture that is easy to spread but has no free liquid." - Berolzheimer R (ed) et al (1959)

Examples:

• Strawberry jam (sweet, fruit)
• Mint jam (savory)
• Jalapeño pepper jam

Variations

Uncooked or minimally cooked (less than 5 minutes) jams, called freezer jam, because they are stored frozen, are popular in parts of North America for their very fresh taste.

Jelly

In the U.S. and Canada, the term jelly refers to a type of clear fruit spread consisting of firmed fruit (or vegetable) juice made with pectin. In British English, these products are commonly referred to by the terms fruit spread or preserves, although jelly is also used in some instances, for example mint jelly. Jelly can be made from sweet, savory or hot ingredients. Jelly is made by a similar process to jam, with the additional step of filtering out the fruit pulp after the initial heating. A cloth "jelly bag" is traditionally used as a filter.

"Good jelly is clear and sparkling and has a fresh flavor of the fruit from which it is made. It is tender enough to quiver when moved, but holds angles when cut.

EXTRACTING JUICE - Pectin is best extracted from the fruit by heat, therefore cook the fruit until soft before straining to obtain the juice ... Pour cooked fruit into a jelly bag which has been wrung out of cold water. Hang up and let drain. When dripping has ceased the bag may be squeezed to remove remaining juice, but this may cause cloudy jelly." - Berolzheimer R (ed) et al (1959)

Examples:

• Grape jelly (sweet fruit)
• Mint jelly (savory)
• Jalapeño pepper jelly (hot)

Marmalade

Main article: Marmalade

British-style marmalade is a sweet preserve with a bitter tang made from fruit, sugar, water, and (in some commercial brands) a gelling agent. American-style marmalade is sweet, not bitter. In English-speaking usage "marmalade" almost always refers to a preserve derived from a citrus fruit, most commonly oranges. The recipe includes sliced or chopped fruit peel, which is simmered in fruit juice and water until soft; indeed marmalade is sometimes described as jam with fruit peel (although perversely many manufacturers now also produce peel-free marmalade). Such marmalade is most often consumed on toasted bread for breakfast. The favoured citrus fruit for marmalade production in the UK is the "Seville orange", Citrus aurantium var. aurantium, thus called because it was originally imported from Seville in Spain; it is higher in pectin than sweet oranges, and therefore gives a good set. Marmalade can also be made from lemons, limes, grapefruits, strawberries or a combination.

Preserves

The term Preserves is usually interchangeable with Jam, however some cookbooks define Preserves as cooked and gelled whole fruit (or vegetable), which includes a significant portion of the fruit.

Conserves

The word "conserve" may be used as an alternative term for jam, conserves may include dried fruit or nuts.

Confit

Main article: Confit

The word "confit," which literally means to preserve in French, and most often applies to meats, can also refer to fruit as when honey or sugar are added in order to extract the water from the fruit. This creates a substance which is similar to preserves and jam.

Fruit butter

Main article: Fruit butter

Fruit butter, is used in this context to refer to a process where the whole fruit is forced through a sieve or blended after the heating process.

"Fruit butters are generally made from larger fruits, such as apples, plums peaches or grapes. Cook until softened and run through a sieve to give a smooth consistency. After sieving, cook the pulp...add sugar and cook as rapidly as possible with constant stirring... The finished product should mound up when dropped from a spoon, but should not cut like jelly. Neither should there be any free liquid." - Berolzheimer R (ed) et al (1959)

Fruit curd

Main article: Fruit curd

Fruit curd is a dessert topping and sandwich spread. The basic ingredients are beaten egg yolks, sugar, lemon juice and zest which are gently cooked together until thick and then allowed to cool, forming a soft, smooth, intensely-flavoured spread. Some recipes also include egg whites and/or butter.

Fruit spread

Fruit spread refers to a jam or preserve with no added sugar.

Regional terminology

The terms jam and jelly are used in different parts of the English speaking world in different ways.

Although both terms exist in North America, the UK and Australia; in the USA most jams are often popularly referred to as "jelly" in a generic way. Meanwhile in the UK, Canada, and Australia the two terms are more strictly differentiated, although the term jam is more popularly used in Australia and South Africa as a generic term. To further confuse the issue, the term jelly is also used in the UK and Australia to refer to a gelatin dessert, whereas in North America the brand name Jell-O is used as a generic term for gelatin desserts and is strictly differentiated from clear fruit preserves.

Production

This section of the article will use the generic term jam unless otherwise noted.

Allowing jam to 'boil over' creates a hazard in the kitchen.

In general jam is produced by taking mashed or chopped fruit or vegetable pulp and boiling it with sugar and water. The proportion of sugar and fruit varies according to the type of fruit and its ripeness, but a rough starting point is equal weights of each. When the mixture reaches a temperature of 104 °C (219 °F), the acid and the pectin in the fruit react with the sugar, and the jam will set on cooling. However, most cooks work by trial and error, bringing the mixture to a "fast rolling boil", watching to see if the seething mass changes texture, and dropping small samples on a plate to see if they run or set.

Jelly Temperature Test – Boil until thermometer reaches 8°F above the boiling temperature of water which varies by altitude: Sea Level - 220°F, 1000 ft - 218°F, 2000 ft - 216°F, 3000 ft - 214°F, 4000 ft - 212°F, 5000 ft - 211°F, 6000 ft - 209°F, 7000 ft - 207°F, 8000 ft - 205°F.

How easily a jam sets depends on the pectin content of the fruit. Some fruits, such as gooseberries, redcurrants, blackcurrants, citrus fruits, apples and raspberries, set very well; others, such as strawberries and ripe blackberries, often need to have pectin added. There are commercial pectin products on the market, and most industrially-produced jams use them. Home jam-makers sometimes rely on adding a pectin-rich fruit to a poor setter; for example blackberry and apple. Other tricks include extracting juice from redcurrants or gooseberries. Making jam at home is a popular handicraft activity, and many take part in this. Homemade jam may be made for personal consumption, or as part of a cottage industry.

Legal definitions

USDA definitions

The USDA treats jam and preserves as synonymous, but distinguishes jelly from jams and preserves. All of these are cooked and pectin-gelled fruit products, but jellies are based entirely on fruit juice or other liquids, while jams and preserves are gelled fruit that includes the seeds and pulp.

European Union directives on 'jam'

In the European Union, the jam directive (Council Directive 79/693/EEC, 24 July 1979) set minimum standards for the amount of "fruit" in jam, but the definition of fruit was expanded to take account of several unusual kinds of jam made in the EU. For this purpose, "fruit" is considered to include fruits that are not usually treated in a culinary sense as fruits, such as tomatoes; fruits that are not normally made into jams; and vegetables that are sometimes made into jams, such as: rhubarb (the edible part of the stalks), carrots, sweet potatoes, cucumbers, and pumpkins. This definition continues to apply in the new directive, Council Directive 2001/113/EC (20 December 2001).
