Kind of spoon
For other uses, seeTeaspoon (disambiguation).

left-to-right:

Ateaspoon (tsp.) is a smallspoon that can be used to stir a cup oftea orcoffee, or as a tool formeasuringvolume.[1][2] The size of teaspoons ranges from about 2.5 to 7.3 mL (0.088 to 0.257 imp fl oz; 0.085 to 0.247 US fl oz). For dosing of medicine and, in places where metric units are used, for cooking purposes, a teaspoonful is defined as 5 mL (0.18 imp fl oz; 0.17 US fl oz), and standardmeasuring spoons are used.[3]

Cutlery

[edit]
A cup of coffee with coffee spoon

A teaspoon is a smallspoon suitable for stirring and sipping the contents of a cup oftea orcoffee, 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 aplace setting.

Teaspoons with longer handles, such asiced tea spoons, are commonly used also forice cream desserts orfloats. Similar spoons include thetablespoon and thedessert 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.[4] Another teaspoon, called anorange spoon (in American English: grapefruit spoon), tapers to a sharp point or teeth, and is used to separatecitrus fruits from their membranes. Abar spoon, equivalent to a teaspoon, is used in measuring ingredients formixed drinks.

A container designed to hold extra teaspoons, called aspooner, usually in a set with a covered sugar container, formed a part of Victorian table service.

History

[edit]
An 1825 cartoon makes fun of a Frenchman unfamiliar with the British etiquette. The guest did not place his spoon into the cup and is thus being offered his thirteenth cup of tea.[5]

The teaspoon is a European invention.[6] Small spoons were common in Europe since at least the 13th century. These special spoons were introduced almost simultaneously with tea and coffee[6] (Pettigrew points to use in the mid-17th century[7]). Originally teaspoons were exotic items, precious and small, resembling thedemitasse spoons of the later times.[6] Also used for coffee, these spoons were usually made ofgilt silver, and were available with a variety of handle shapes: plain, twisted, decorated with knobs,[7] also known asknops, hence theknop-top name for such spoons.[8] Widespread use and modern size date back to theGeorgian era.[6] The teaspoon is first mentioned in an advertisement in a 1686 edition of theLondon Gazette,[9][10] teaspoons, probably of English origin, are present on the 1700 Dutch painting byNicholas Verkolje, "A Tea Party".[11]

A special dish for resting the teaspoons, a "spoon boat", was a part of thetea set in the 18th century.[12] 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.[13][14] Pettigrew reports that sometimes the spoons were numbered to make it easier to match the cups with the guests after a refill.[13]

In some countries, a teaspoon (occasionallyteaspoonful) is acooking measure ofvolume, especially widely used in cooking recipes and pharmaceutic medical prescriptions. In English it is abbreviated astsp. or, less often, ast.,ts., ortspn.. The abbreviation is never capitalized because a capital letter is customarily reserved for the largertablespoon ("Tbsp.", "T.", "Tbls.", or "Tb.").[15]

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 71 teaspoons from 25 houses and found that the volume varied between 2.5 and 7.3 mL (0.088 and 0.257 imp fl oz; 0.085 and 0.247 US fl oz).[16]

Dry ingredients

[edit]

For dry granular or powdered ingredients (e.g.,salt,flour,spices, and especially beverages involvingtea andsugar),[21] 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 particular, in a typical American recipe a "spoon" without clarification stands for a "level" spoon (the one with no ingredient showing above the rim of the spoon bowl), while a British cookbook would mean a "round" or "heaped" spoon, with the ingredient peaking above the rim:[22]

  • Ascant teaspoon is one which has been filled to slightly less than level.[23]
  • Alevel teaspoon, which is the defaultteaspoon 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.[24]
  • Arounded 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.[24]
  • Aheaping (North American English) orheaped (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.[24] Many cookbooks treat heaped and rounded spoons interchangeably.[25][26]

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).[27]

Apothecary

[edit]
See also:Apothecaries' system

As an unofficial but once widely used unit ofapothecaries' measure, the teaspoon is equal to 1 fluid dram (or drachm) and thus14 of a tablespoon or18 of a fluid ounce.[28][29] The apothecaries' teaspoon was formally known by the Latincochleare minus (cochl. min.) to distinguish it from the tablespoon orcochleare majus (cochl. maj.).[30][31]

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 theCommutation Act reduced the tax on tea from 119% to 12.5%.[32] 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 to13 of a tablespoon, but the apothecary unit of measure remained the same.[33] 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.
