Digestive biscuit

Digestive biscuits

A digestive biscuit, sometimes referred to as a sweet-meal biscuit, is a semi-sweet biscuit originated in the United Kingdom and popular worldwide. The term 'digestive' is derived from the belief that they had antacid properties due to the use of sodium bicarbonate when they were first developed.^[1] Historically, some producers used diastatic malt extract to 'digest' some of the starch that existed in flour prior to baking.^[2][3]

History

McVitie & Price's Digestive tin box

Digestives are known at least as far back as advertisements for Huntley & Palmers in 1876, with a recipe being given in Cassell's 'New Universal Cookery Book' of 1894.^{[4][clarification needed]} Even further back, one 1851 issue of The Lancet London advertised at least two sources of digestive biscuits, one such baker, William Hill, offered "brown meal digestive biscuits".^[5] At the time, it was asserted grain millers knew only of bran and endosperm.^[6] After 10% of the grain's coarser outer-bran coat was removed, and because the innermost 70% of pure endosperm was reserved for other uses, brown meal, representing only 20% of the whole grain, remained, and was itself composed of about 15% fine bran and 85% white flour.^[7] By 1912 it was more widely known that brown meal included the germ, which lent a characteristic sweetness.^[8]

In 1889, John Montgomerie of Scotland filed a U.S. patent application which was granted in 1890. This patent asserted a prior patent existed in England dated 1886. The U.S. patent titled Making Malted Bread included instructions for the manufacture of digestive biscuits. Montgomerie claimed this saccharification process would make "nourishing food for people of weak digestion ..."^[9]

Despite rumours^[10] that it is illegal for them to be sold under their usual name in the United States,^[11] they are in fact widely available in imported food sections of grocery stores and by mail order.^[12] In the United States, buying digestive biscuits may require a visit to an international market or you can order them from international retailers (such as world.com) that have an Internet presence.

Ingredients

The typical digestive biscuit contains coarse brown wheat flour (which gives it its distinctive texture and flavour), sugar, malt extract, vegetable oil, wholemeal, raising agents (usually sodium bicarbonate, tartaric acid and malic acid) and salt.^[13] Dried whey, oatmeal, cultured skimmed milk and/or emulsifiers such as E472e may also be added in some varieties. Digestive biscuits may not be suitable for nut or soya allergy sufferers due to certain production methods. Careful reading of packaging and or contact with manufacturers should be performed to satisfy any concerns regarding cross contamination.

Digestive biscuits outside of the United States, like many foods, are not reliant on the addition of high-fructose corn syrup (sometimes referred to as "glucose-fructose syrup"), and hence may add more natural sugar instead, such as in New Zealand^[14] or in the United Kingdom.^[15]

A digestive biscuit averages around 70 calories, although this sometimes varies according to the factors involved in its production.

Consumption

Digestive biscuits are frequently eaten with tea or coffee. Sometimes, the biscuit is dunked into the tea and eaten quickly due to the biscuit's tendency to disintegrate when wet.

In the UK alone, the annual sales of chocolate digestives total about £35 million. This means that each year, 71 million packets of these are sold - and each second 52 biscuits are consumed.^[1] Digestives are also popular in food preparation for making into bases for cheesecakes and similar desserts.^[16]

Chocolate digestive biscuits also are available, coated on one side with milk, dark or white chocolate. Originally produced by McVitie's in 1925 as the Chocolate Homewheat Digestive, other recent varieties include the basic biscuit with chocolate shavings throughout (chocolate 'chips' within the biscuit mix), or a layer of caramel, mint chocolate, orange-flavoured chocolate,^[17] or plain chocolate. American travel writer Bill Bryson described the chocolate digestive as a British masterpiece.^[18]

Recipe substitution

In recipes calling for digestive biscuits, it is common to substitute Graham crackers in the United States and Canada. According to Charles Panati, the original Graham cracker is called a "digestive biscuit" in Britain.^[19]

Prepared from it was exhibited a series of digestive biscuits, rusks and bread by John Montgomerie, of Glasgow. In making these part of the starch of the flour is changed by being mixed with the malt extract and water and kept for some time at a suitable temperature; the yeast being probably added to another portion of flour and water, to form dough to mix with the above before baking. These biscuits seemed to be appreciated by visitors. Messrs. Hill and Son also exhibited some malted nursery biscuits. Benger's wellknown digestive ferments were well displayed, together with an essence of rennet recently introduced."
