Conferf Van Framboisen
"Neemt van de schoonste Kerssen, doet 'er de Steenen uit, en laat ze een weinig in een weinigje Waters kooken, laatze voorts verzygen, peltse en droogtse wel. Dit gedaan zynde, voegt 'er dan eenige handen vol Framboisen by met haare Kernen; of anders, houd u te vreden met uwe Framboisen door te wringen, en het Zap met uwe Kerssen te mengen; daarna zult gy Suiker à Cassé, dat is aan Brocken, kooken, gy zult daar uwe Compositie by doen, en het alles braaf bearbeiden; dus je Conferf gemaakt zynde, zult gy ze opscheppen als de andere, en mede zoo snyden."
English Translation
"Take the finest cherries, remove the stones, and let them cook for a little while in a small amount of water. Then let them drain well, peel them, and dry them thoroughly. When this is done, add a few handfuls of raspberries with their seeds; or otherwise, be content with pressing your raspberries and mixing the juice with your cherries. Then you will boil sugar à cassé, that is, in pieces; you will add your mixture to it and work it all together thoroughly. Once your conserve is made, you will scoop it out as you would the others, and likewise cut it."
Note on the Original Text
The recipe is written in the spare, instructional style typical of early 18th-century kitchen manuals: direct, relying on practical knowledge, and omitting precise measurements. Spelling reflects contemporary Dutch usage, with words like 'Neemt,' 'doet 'er,' and 'bearbeiden,' which may differ noticeably from modern Dutch orthography. Instructions are grouped together, assuming the reader's familiarity with kitchen basics. The use of 'Suiker à Cassé' refers to boiling sugar to the hard-crack stage, a common preserving technique before the widespread availability of jam-making pectins.

This recipe is drawn from the 1725 Dutch cookbook, 'Het Hollands, of Neederlands kook-boek.' During this era, fruit preserves and 'conferf' (a type of firm fruit conserve or paste) were popular as both delicacies and methods for preserving summer fruits through the year. The technique embodies the culinary ingenuity of 18th-century Dutch households, where sugar became increasingly accessible and fruit cookery flourished. The recipe highlights the resourceful use of available fruit—cherries and raspberries—and the process of preserving their vibrant flavors for later enjoyment, reflecting both the seasonality of ingredients and the practical preservation methods of the day.

Back in the early 18th century, cooks would have employed a sturdy iron or copper kettle for simmering the fruit and dissolving the sugar. Wooden spoons were used for stirring, and a sieve or coarse cloth would help in straining the fruit. Finished preserves would be set in shallow earthenware or pewter trays, and once cooled, a sharp knife was used for slicing the firm confection. Open hearths provided the heat, requiring careful attention to temperature by the cook, especially when heating sugar to the 'cassé' stage.

Ingredients
- 1 lb 2 oz sweet cherries, pitted
- 5 oz fresh raspberries, whole or juice
- 3.4 fl oz water
- 12.3 oz granulated sugar
Instructions
- To make 'Conferf van Framboisen' as described in the 1725 Dutch cookbook, begin by taking about 1 lb 2 oz of the freshest, high-quality cherries.
- Remove their pits, then simmer them gently in a small amount of water (approximately 3.4 fl oz) until they start to soften and release juice—about 10 minutes.
- Strain the cherries, peel off the skins if possible, and dry them well.
- Next, add a few handfuls (about 5 oz) of fresh raspberries, including their seeds, to the cherries.
- If you do not have enough whole raspberries, crush the raspberries and squeeze to extract their juice, mixing this juice with the prepared cherries.
- Take granulated sugar (about 12.3 oz) and heat until it forms hard lumps or cracks (known as 'à cassé' stage, 284-302°F).
- Mix your cherry-raspberry blend with the hot sugar and stir diligently until fully incorporated.
- Once your 'conferf' has thickened and is glossy, transfer it to a container.
- Let it cool, then cut into slices to serve.

Cooking Estimates
Preparing and pitting the cherries takes about 15 minutes. Simmering the cherries takes 10 minutes, while straining and mixing with raspberries takes another 10 minutes. Heating the sugar and combining everything adds another 10 minutes. The finished conferf is quite sweet and dense, so the recipe can be cut into about 10 servings. Each serving contains around 180 calories, mainly from the sugar and fruit.
