Strawberry Preserves
Cap the berries. Put one and a half pounds sugar to each pound fruit. Let them stand two or three hours, and then boil thirty minutes.
Three sentences that assume you already know what a preserving kettle is. The proportions are sound; the timing and the storage need translating.
- "Cap the berries"Capping means removing the green calyx and hull, which was done with the fingers or the point of a knife. Choose berries that are ripe but firm — soft fruit collapses into jam rather than holding its shape in syrup.
- Weigh, don't measureOne and a half pounds sugar to each pound of hulled fruit is a weight ratio, not a volume one. Two pounds of berries takes three pounds of sugar, which is roughly 6 3/4 cups — a very high-sugar preserve by current taste, and the reason it sets and keeps without added pectin.
- The standing time is the pointThe two or three hours of maceration draws juice out of the fruit and dissolves the sugar before any heat is applied. Skip it and you get scorched sugar on the bottom and hard, shrunken berries on top.
- Thirty minutes is longA modern preserve is boiled hard until it reaches the gel point, 220F at sea level, which with this much sugar usually takes 10 to 20 minutes. Thirty minutes of open boiling will darken the syrup and taste caramelised; start testing early with a chilled plate or a thermometer.
- Skim, and use a wide panStrawberries throw a great deal of pink foam. Skim it off as it rises for a clear syrup, and use the widest heavy pan you have so the water evaporates fast and the fruit spends less time cooking.
- Acid and pectinStrawberries are low in both, which is why old recipes lean so heavily on sugar. A tablespoon or two of lemon juice per pound of fruit improves the set and brightens a flavour that thirty minutes of boiling tends to flatten.
- Storage is not addressedThe original stops at the boil; no sealing or processing of any kind is described. For shelf storage, follow current water-bath canning directions for jars and times; otherwise refrigerate and eat within a few weeks.
- YieldTwo pounds of berries with three pounds of sugar gives roughly five to seven half-pint jars, depending on how far you boil it down.
Housekeeping in Old Virginia (1879), compiled by Marion Cabell Tyree from contributions by some 250 Virginia housekeepers, belongs to a period when preserving was arithmetic rather than instruction: name the fruit, give the sugar ratio, name a boiling time, and trust that the cook has done it every June of her life. The pound-and-a-half-to-a-pound proportion is heavier than the equal-weight rule common for firmer fruits, and reflects both the wateriness of strawberries and the fact that sugar was the preservative — a preserve kept because its syrup was too concentrated to spoil, not because it had been processed. Recipes like this one are also a reminder of how short the strawberry season was: the fruit appeared for a few weeks, was put up in quantity, and then did not reappear until the following year.
