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 and r ... [...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 do ...

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 biology, molecular and cell biology, much like ''Escherichia coli'' as the model bacteria, bacterium. It is the microorganism behind the most common type of fermentation (biochemistry), fermentation. ''S. cerevisiae'' cells are round to ovoid, 5–10 micrometre, μm in diameter. It reproduces by budding. Many proteins important in human biology were first discovered by studying their Homology (biology), 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 body, Berkeley bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
