Garibaldi biscuit
The Garibaldi biscuit consists of currants squashed and sandwiched between two thin oblongs of biscuit dough before baking. The biscuits are similar to Eccles cake as well as the Golden Fruit Raisin Biscuits once made by Sunshine Biscuits. Popular with British consumers as a snack for over 150 years, the Garibaldi biscuit is conventionally consumed with tea or coffee. The biscuits also exist under different names in other countries, including Australia and New Zealand (with the name "Fruitli Golden Fruit"). In The Netherlands, a similar biscuit, called Sultana, has been produced since 1935 by Verkade. When bought in supermarkets in the UK (under several brands, all very similar), Garibaldi biscuits usually come in four strips of five biscuits each. They have a golden brown, glazed exterior and a moderately sweet pastry, but their defining characteristic is the layer of squashed fruit which gives rise to the colloquial names fly sandwiches, flies' graveyards, dead fly biscuits,[citation needed], squashed fly biscuits, or in New Zealand, fly traps, because the squashed fruit resemble squashed flies.
