With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1] The carbon snake experiment can sometimes be misidentified as the black snake , "sugar snake", or "burning sugar" reaction, all of which involve baking soda rather than sulfuric acid.
The amount of solid chemicals dissolved in the experiment could be reduced from 60 grams to 6 grams. And the pH could be lowered from 13 to 3 which is easier to neutralize the pH to 7 by adding baking soda before disposal. [16] Also, it is safer and the reactions also occur faster and are easier to perform.
For example, in a recipe that calls for 10 pounds of flour and 5 pounds of water, the corresponding baker's percentages are 100% for the flour and 50% for the water. Because these percentages are stated with respect to the weight of flour rather than with respect to the weight of all ingredients, the sum of these percentages always exceeds 100%.
To take advantage of this style of leavening, the baking must be done at high enough temperatures to flash the water to steam, with a batter that is capable of holding the steam in until set. This effect is typically used in products having one large cavity, such as popovers, Yorkshire puddings, pita, and most preparations made from choux pastry.
In domestic cooking, bulk solids, notably flour and sugar, are measured by volume, often cups, though they are sold by weight at retail. Weight measures are used for meat . Butter may be measured by either weight ( 1 ⁄ 4 lb) or volume (3 tbsp) or a combination of weight and volume ( 1 ⁄ 4 lb plus 3 tbsp); it is sold by weight but in ...
The crusts of most breads, such as this brioche, are golden-brown mostly as a result of the Maillard reaction. The Maillard reaction ( / m aɪ ˈ j ɑːr / my- YAR ; French: [majaʁ] ) is a chemical reaction between amino acids and reducing sugars to create melanoidins , the compounds that give browned food its distinctive flavor.
A weaker flour, such as a cake or pastry flour with a much lower gluten content would have a much steeper decline after peak time. The points of interest on the graph are fivefold: Arrival Time (Absorption) – Absorption is the point chosen by the baking industry which represents a target water to flour ratio in bread .
A soda geyser is a physical reaction between a carbonated beverage, usually Diet Coke, and Mentos mints that causes the beverage to be expelled from its container. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle.
