Barm
Barm is the foam or scum formed on the top of a fermenting liquid, such as beer, wine, or feedstock for spirits or industrial ethanol distillation. It is used to leaven bread, or set up fermentation in a new batch of liquor. Barm, as a leaven, has also been made from ground millet combined with must out of wine-tubs and is sometimes used in English baking as a synonym for a natural leaven (sourdough). Reinhart derived the term from his training undeMonica Spiller Various cultures derived from barm, usually ''Saccharomyces cerevisiae'', became ancestral to most forms of brewer's yeast and baker's yeast currently on the market. In Ireland, barm is used in the traditional production of barmbrack, a fruited bread. Despite the name, the barm cakes of northern England are not necessarily made with barm.

Barm Cake
A barm cake is a soft, round, flattish bread roll from North West England, traditionally leavened with barm. Chips are a popular filling, sold in most fish and chip shops in the North West of England and often called a chip barm. Another popular filling in the North West, particularly Greater Manchester, is a pasty barm. In Wigan, a whole savoury pie is served in a barm cake, known locally as a "Wigan Kebab".

Barmbrack
Barmbrack ( ga, bairín breac), also often shortened to brack, is a yeast bread with added sultanas and raisins. The bread is associated with Halloween in Ireland, where an item (often a ring) is placed inside the bread, with the person who receives it considered to be fortunate. Etymology It is sometimes called , and the term is also used as two words in its more common version. This may be from the Irish word - - and - (due to the raisins in it), hence it literally means a speckled loaf (a similar etymology to the Welsh ). Other origins for "barm" could relate to the use of the froth from fermented ale, which is a form of yeast referred to as barm. This was used in place of bicarbonate soda in baking, as it was not widely available in Ireland until the early 19th century. Description Usually sold in flattened rounds, it is often served toasted with butter along with a cup of tea. The dough is sweeter than sandwich bread, but not as rich as cake, and the sultanas an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sourdough
Sourdough or sourdough bread is a bread made by the fermentation of dough using wild lactobacillaceae and yeast. Lactic acid from fermentation imparts a sour taste and improves keeping qualities. History In the ''Encyclopedia of Food Microbiology'', Michael Gaenzle writes: "The origins of bread-making are so ancient that everything said about them must be pure speculation. One of the oldest sourdough breads dates from 3700 BCE and was excavated in Switzerland, but the origin of sourdough fermentation likely relates to the origin of agriculture in the Fertile Crescent and Egypt several thousand years earlier", which was confirmed a few years later by archeological evidence. ... "Bread production relied on the use of sourdough as a leavening agent for most of human history; the use of baker's yeast as a leavening agent dates back less than 150 years." Pliny the Elder described the sourdough method in his '' Natural History'': Sourdough remained the usual form of leavening d ...

Bread
Bread is a staple food prepared from a dough of flour (usually wheat) and water, usually by baking. Throughout recorded history and around the world, it has been an important part of many cultures' diet. It is one of the oldest human-made foods, having been of significance since the dawn of agriculture, and plays an essential role in both religious rituals and secular culture. Bread may be leavened by naturally occurring microbes (e.g. sourdough), chemicals (e.g. baking soda), industrially produced yeast, or high-pressure aeration, which creates the gas bubbles that fluff up bread. In many countries, commercial bread often contains additives to improve flavor, texture, color, shelf life, nutrition, and ease of production. History Bread is one of the oldest prepared foods. Evidence from 30,000 years ago in Europe and Australia revealed starch residue on rocks used for pounding plants. It is possible that during this time, starch extract from the roots of plants, such as c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saccharomyces Cerevisiae
''Saccharomyces cerevisiae'' () (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungus microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes. It is one of the most intensively studied eukaryotic model organisms in molecular and cell biology, much like '' Escherichia coli'' as the model bacterium. It is the microorganism behind the most common type of fermentation. ''S. cerevisiae'' cells are round to ovoid, 5–10 μm in diameter. It reproduces by budding. Many proteins important in human biology were first discovered by studying their homologs in yeast; these proteins include cell cycle proteins, signaling proteins, and protein-processing enzymes. ''S. cerevisiae'' is currently the only yeast cell known to have Berkeley bodies present, which are involved in particular secretory pathways. Antibodies agains ...

Kaiser Roll
The Kaiser roll (''Emperor roll'', german: Kaisersemmel), also called a Vienna roll (; as made by hand also: , sl, kajzerica), or a hard roll, is a typically crusty round bread roll, originally from Austria. It is made from white flour, yeast, malt, water and salt, with the top side usually divided in a symmetric pattern of five segments, separated by curved superficial cuts radiating from the centre outward or folded in a series of overlapping lobes resembling a crown. The crisp is a traditional Austrian food officially approved by the Federal Ministry of Agriculture. Origin Kaiser rolls have existed in a recognizable form since at least 1760. They are thought to have been named to honor Emperor () Franz Joseph I of Austria (born 1830, reigned 1848–1916). In the 18th century a law fixed retail prices of (bread rolls) in the Habsburg monarchy. Allegedly, the name came into general use after the bakers' guild sent a delegation in 1789 to Emperor Joseph II ( 1741, 1765 ...

Leavening Agent
In cooking, a leavening agent () or raising agent, also called a leaven () or leavener, is any one of a number of substances used in doughs and batters that cause a foaming action (gas bubbles) that lightens and softens the mixture. An alternative or supplement to leavening agents is mechanical action by which air is incorporated (i.e. kneading). Leavening agents can be biological or synthetic chemical compounds. The gas produced is often carbon dioxide, or occasionally hydrogen. When a dough or batter is mixed, the starch in the flour and the water in the dough form a matrix (often supported further by proteins like gluten or polysaccharides, such as pentosans or xanthan gum). The starch then gelatinizes and sets, leaving gas bubbles that remain.

Baker's Yeast
Baker's yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species ''Saccharomyces cerevisiae'', and is the same species (but a different strain) as the kind commonly used in alcoholic fermentation, which is called brewer's yeast. Baker's yeast is also a single-cell microorganism found on and around the human body. The use of steamed or boiled potatoes, water from potato boiling, or sugar in a bread dough provides food for the growth of yeasts; however, too much sugar will dehydrate them. Yeast growth is inhibited by both salt and sugar, but more so by salt than sugar. Some sources say fats, such as butter and eggs, slow down yeast growth; others say the effect of fat on dough remains unclear, presenting evid ...

Fermentation (food)
In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic (oxygen-free) conditions. Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy. The term "fermentation" sometimes refers specifically to the chemical conversion of sugars into ethanol, producing alcoholic drinks such as wine, beer, and cider. However, similar processes take place in the leavening of bread (CO2 produced by yeast activity), and in the preservation of sour foods with the production of lactic acid, such as in sauerkraut and yogurt. Other widely consumed fermented foods include vinegar, olives, and cheese. More localised foods prepared by fermentation may also be based on beans, grain, vegetables, fruit, honey, dairy products, and fish. History and prehistory Natural fermentation precedes human history. Since ancient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sour Mash
Sour mash (or sourmash) is a process used in the distilling industry that uses material from an older batch of mash to start the fermentation of a new batch, analogous to the making of sourdough bread with a starter. The term can also be used as the name of the type of mash used in such a process, and a bourbon made using this process can be referred to as a ''sour mash bourbon''. Sour beer may also be created with this process. Process In the sour mash process, the mash – a mixture of grain, malt and water – is conditioned with some amount of spent mash (previously fermented mash that still contains dead yeast, a good food source for live yeast). Spent mash is also known as spent beer, distillers' spent grain, and slop or feed mash because it is also used as animal feed. The acid introduced by the sour mash controls the growth of bacteria that could taint the Bourbon. An established and active strain of live yeast is introduced into the mash to be fermented. ...

Brewer's Yeast
Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms that evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 µm in diameter, although some yeasts can grow to 40 µm in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) are called ...

English Cuisine
English cuisine encompasses the cooking styles, traditions and recipes associated with England. It has distinctive attributes of its own, but also shares much with wider British cuisine, partly through the importation of ingredients and ideas from the Americas, China, and India during the time of the British Empire and as a result of post-war immigration. Some traditional meals, such as bread and cheese, roasted and stewed meats, meat and game pies, boiled vegetables and broths, and freshwater and saltwater fish have ancient origins. The 14th-century English cookbook, the '' Forme of Cury'', contains recipes for these, and dates from the royal court of Richard II. English cooking has been influenced by foreign ingredients and cooking styles since the Middle Ages. Curry was introduced from the Indian subcontinent and adapted to English tastes from the eighteenth century with Hannah Glasse's recipe for chicken "currey". French cuisine influenced English recipes throughout the V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
