Note on the Original Text
This recipe, typical of its time, uses idiosyncratic spelling and punctuation ('ym' for 'them'; 'boyleing' for 'boiling'; 'bisketts' for 'biscuits'), and assumes the cook is already quite skilled. Directions are more narrative than scientific, with quantities given by weight and volume rather than precise ratios. The process relies heavily on the cook’s judgment for doneness and heat—no thermometers or timers here! Being written in a freeform way, the instructions blend technique and ingredient additions together, making close reading essential. The emphasis on beating the mixture 'in a Brass or Silver pan' and heating until 'you cannot keep your fingers in it' shows an intuitive, tactile approach to kitchen science long before the standardization of recipes.

This recipe for 'Spunge Bisketts' is adapted from a mid-18th-century English manuscript compiled by Mary Puleston before 1764. The Puleston family were members of the landed gentry, and their recipe collection offers a glimpse into the refined tastes and culinary creativity of Georgian Britain. At the time, sponge biscuits like these were exquisitely fashionable, frequently served at social teas or as elegant desserts. Novel methods in egg foaming and careful handling of ingredients foreshadow the rise of modern patisserie. The use of rose water and lemon zest is typical of the period’s love for floral and citrus notes, elevating otherwise simple pantry staples.

In Mary Puleston's kitchen, this recipe would have required a large brass or silver mixing pan, a sturdy whisk or bundle of birch twigs (the forerunner of the modern whisk), and a set of small oblong tins or pans for shaping the sponge biscuits. Heat was applied using a hearth or range, often with pans set over gently simmering water to carefully regulate the temperature while whisking the eggs (today's bain-marie). Ingredients were sifted through muslin or a fine sieve. Sugar was often sold in cones and grated or pounded before use. Baking was done in a 'quick oven', meaning a hot wood-fired or coal oven, monitored by hand and experience.

Ingredients
- 18 egg yolks
- 9 egg whites
- 2 lb 3 oz granulated sugar, sifted
- 1 cup plus 2 tablespoons water
- 1.5 fl oz (3 tablespoons) rose water
- 1 lb 8 oz plain (all-purpose) flour, dried or sifted
- Zest of 2 lemons
- Butter (for greasing tins/pans)
- Extra sugar (for sprinkling before baking)
Instructions
- To prepare these historical 'Sponge Biscuits' (early sponge fingers or ladyfingers) in a modern kitchen, start by separating 18 egg yolks and 9 egg whites.
- Whip the yolks and whites together until light and frothy in a stand mixer or with a hand whisk.
- Gradually add 2 lb 3 oz of sifted white sugar while beating.
- Meanwhile, heat 1 cup plus 2 tablespoons water with 3 tablespoons (about 1.5 fl oz) of rose water to boiling.
- Slowly pour the hot rose water mixture, bit by bit, into the eggs and sugar as you continue whisking.
- If possible, use a heatproof metal bowl set over barely simmering water (bain-marie style) to gently heat the mixture, whisking constantly, until it is very hot (but not scrambled)—around 140°F (60°C), or until you can just barely keep your finger in it.
- Remove from heat and continue whisking until just cool.
- Sift in 1 lb 8 oz of well-dried (or plain) flour and the grated zest of 2 lemons, folding gently to keep the mixture airy.
- Spoon or pipe the batter into buttered oblong moulds or small loaf pans (or onto a lined baking tray in finger shapes), dust generously with more sifted sugar, and bake in a preheated, hot oven (about 390°F/200°C) until lightly golden and springy.
- Allow to cool before handling.
