Teaspoon

A teaspoon is a small spoon suitable for stirring and sipping the contents of a cup of tea or coffee, or adding a portion of loose sugar to it. These spoons have heads more or less oval in shape. Teaspoons are a common part of a place setting. Teaspoons with longer handles, such as iced tea spoons, are commonly used also for ice cream desserts or floats. Similar spoons include the tablespoon and the dessert spoon, the latter intermediate in size between a teaspoon and a tablespoon, used in eating dessert and sometimes soup or cereals. Much less common is the coffee spoon, which is a smaller version of the teaspoon, intended for use with the small type of coffee cup. Another teaspoon, called an orange spoon (in American English: grapefruit spoon), tapers to a sharp point or teeth, and is used to separate citrus fruits from their membranes. A bar spoon, equivalent to a teaspoon, is used in measuring ingredients for mixed drinks. A container designed to hold extra teaspoons, called a spooner, usually in a set with a covered sugar container, formed a part of Victorian table service. == History ==

The teaspoon is a European invention. Small spoons were common in Europe since at least the 13th century. These special spoons were introduced almost simultaneously with tea and coffee in the mid-17th century. Originally teaspoons were exotic items, precious and small, resembling the demitasse spoons of the later times. Also used for coffee, these spoons were usually made of gilt silver, and were available with a variety of handle shapes: plain, twisted, decorated with knobs, also known as knops, hence the knop-top name for such spoons. Widespread use and modern size date back to the Georgian era. The teaspoon is first mentioned in an advertisement in a 1686 edition of the London Gazette. Teaspoons, probably of English origin, are present on the 1700 Dutch painting by Nicholas Verkolje, "A Tea Party". A special dish for resting the teaspoons, a "spoon boat", was a part of the tea set in the 18th century. At that time, the spoons were playing important role in the tea drinking etiquette: a spoon laid "across" the teacup indicated that the guest did not need any more tea, otherwise, the hostess was obligated to offer a fresh cup of tea, and it was considered impolite to refuse the offering. Sometimes the spoons were numbered to make it easier to match the cups with the guests after a refill. == Unit of measure ==

In some countries, a teaspoon (occasionally teaspoonful) is a cooking measure of volume, especially widely used in cooking recipes and pharmaceutic medical prescriptions. In English it is abbreviated as tsp. or, less often, as t., ts., or tspn.. The abbreviation is never capitalized because a capital letter is customarily reserved for the larger tablespoon ("Tbsp.", "T.", "Tbls.", or "Tb."). A small scale study in Greece found that household teaspoons are a poor approximation of the standard tsp measure. The study investigated the accuracy of teaspoons as a measuring tool for liquid medicine. They surveyed from 25 houses and found that the volume varied between . Metric teaspoon The metric teaspoon as a unit of culinary measure is 5 mL, equal to , international metric tablespoon, or Australian metric tablespoon. United States customary unit As a unit of culinary measure, one teaspoon in the United States is tablespoon, exactly  millilitres (mL), 1 US customary fluid drams, US customary fl. oz, US cup, US liquid gallon, or  (0.30078125) cubic inches. For nutritional labeling and medicine in the US, the teaspoon is defined the same as a metric teaspoonprecisely 5 millilitres (mL). British culinary measurement unit Traditionally, in the United Kingdom, is 1 British imperial fluid drachm ( British imperial fluid ounce). 1 UK teaspoon is the equivalence of UK tablespoon, UK dessert spoon, or 2 UK salt spoons. Dry ingredients For dry granular or powdered ingredients (e.g., salt, flour, spices, and especially beverages involving tea and sugar), a recipe may call for the spoon to be filled in a certain way that changes the volume of the ingredient. As with much of cooking, these measures are by their nature inexact. This can be exacerbated here by failing to use a real teaspoon: a teaspoon's greater area supports considerably more to be heaped above it than a deeper hemispherical measuring spoon, so if using a measuring spoon, one will typically use less than called for by the recipe. The definitions of "spoonful" vary. In American recipes, a "spoon" without clarification stands for a "level" spoon, with no ingredient showing above the rim of the spoon bowl. A British cookbook would mean a "round" or "heaped" spoon, with the ingredient peaking above the rim: • A scant teaspoon is one which has been filled to slightly less than level. • A level teaspoon, which is the default teaspoon if no adjective is given, refers to an approximately leveled filling of the spoon, producing the same volume as for liquids. The excess of ingredient can be scraped off by a knife. • A rounded teaspoon is roughly symmetrical with as much ingredient above the rim as is in the spoon below the rim, giving a measure roughly equivalent to two level teaspoons. • A heaping (North American English) or heaped (UK English) teaspoon is a larger inexact measure consisting of the amount obtained by scooping the dry ingredient up as high as possible to balance on a spoon. This quantity can vary considerably, up to 5 amounts of ingredient in the level spoon. Many cookbooks treat heaped and rounded spoons interchangeably. Lincoln used the spoon measure without adjectives to define either a rounded one (for flour and sugar) or a level one (for salt and spices). Apothecary As an unofficial but once widely used unit of apothecaries' measure, the teaspoon is equal to 1 fluid dram (or drachm) and thus of a tablespoon or of a fluid ounce. The apothecaries' teaspoon was formally known by the Latin cochleare minus (cochl. min.) to distinguish it from the tablespoon or cochleare majus (cochl. maj.). When tea-drinking was first introduced to England circa 1660, tea was rare and expensive, as a consequence of which teacups and teaspoons were smaller than today. This situation persisted until 1784, when the Commutation Act reduced the tax on tea from 119% to 12.5%. As the price of tea declined, the size of teacups and teaspoons increased. By the 1850s, the teaspoon as a unit of culinary measure had increased to of a tablespoon, but the apothecary unit of measure remained the same. Nevertheless, the teaspoon, usually under its Latin name, continued to be used in apothecaries' measures for several more decades, with the original definition of one fluid dram. ==See also==
