To Preserve Wallnuts
"Take green Wallnuts before they bee shelled, (before midsumer) prick them full of holes, lay them in water 4 or 5 Dayes; shift them twice or thrice a day, then put them in a Skillet of water, set them on ye fire, till ye water is boiling hot; then put them out, & put them in more water when tis warm; so shift them, till it colours no more; boil them a little ye last time, then take them up, & wipe them with a coarse cloth till ye Skin is off; then take to a pound of Wallnuts a pound of Sugar, & a Quart of water, & make it into Syrup; then prick yor Wallnuts with a stick of Cinnamon & a Clove; let them boil leisurely for an hour, then set them by for a week, & then you must make a fresh Syrup of good Sugar."
Note on the Original Text
Recipes of this period were transmitted orally or in manuscript, meant for experienced cooks who knew standard kitchen techniques. Measurements are given by weight (pounds) or volume (quarts), without standardization. Directions are sequential, lacking explicit times or temperatures—and counting on a practiced sense of readiness ('shift them, till it colours no more'). Spelling is phonetic ('wallnuts', 'boil them a little ye last time') and punctuation is loose, making historical context essential to understanding. Clarifications: 'wallnuts' are 'walnuts', 'yor' is 'your', and 'bee shelled' means before their shells are hard.

This recipe hails from late 17th-century England, attributed to Mary Cruso in 1689. Preserving green walnuts was a seasonal tradition, taking advantage of their short period of edibility before hard shells formed. Such preserves were enjoyed as luxurious sweetmeats, often accompanying cheese, game, or as delights at the end of elaborate feasts. Sugar was expensive but increasingly accessible in upper-middle-class English households, while spices like cinnamon and cloves signified hospitality and status. The meticulous method of soaking and blanching reflects both concerns for bitterness and the indulgence of time-rich foodways of the era.

The original recipe would have been made with simple household tools of the period: a sharp skewer or fine fork for pricking the walnuts, a large earthenware or wooden bowl for soaking, an iron or brass skillet or saucepan for blanching and boiling, and a linen or coarse cloth for peeling skins. For boiling syrup, cooks would have used a heavy-bottomed pan over an open hearth or kitchen range, adjusting heat with coals and judging readiness by eye and taste.

Ingredients
- 1 lb young, green walnuts (pre-shelled, before mid-summer)
- 1 lb white granulated sugar
- 1 quart water (for making syrup; extra water needed for soaking and blanching)
- 10–12 whole cloves
- 1–2 sticks of cinnamon, broken for piercing
- Coarse cloth for rubbing skins
- Optional: additional water for successive blanchings
Instructions
- To recreate this 17th-century walnut preserve, begin by sourcing young, green walnuts—try to find them before the shells begin to harden, usually before late June.
- Using a sturdy pin or skewer, prick each walnut with holes all over.
- Soak the walnuts in a bowl of cold water for 4–5 days, changing the water 2–3 times daily to draw out bitterness.
- Next, place the drained walnuts in a saucepan, cover with water, and heat until the water is just boiling.
- Drain and repeat this blanching with fresh warm water several times until the water runs clear and no longer stains.
- For the final blanch, boil the walnuts for a few minutes, then drain and rub off the skins with a coarse cloth.
- Prepare a syrup by dissolving an equal weight of white sugar to cleaned walnuts (e.g., 1 lb walnuts to 1 lb sugar) in water (1 quart per 1 lb walnuts) and heat just to dissolve.
- Pierce each walnut with a small stick of cinnamon and a clove.
- Add the walnuts to the syrup and simmer gently for about an hour.
- Store the walnuts in their syrup for a week, then prepare a fresh batch of syrup and re-cover the walnuts for longer storage.
