Strawberry Jam

I was recently gifted an overload of strawberries: I bought four baskets from a vendor at the market, whose booth I shop at often, and he threw in two extra baskets for free, the equivalent of a carte de fidelité (loyalty card) in Paris. So I’ve spent the past few days washing, hulling, cutting and cooking my unexpected bounty.

I’ve been making a number of things with the gorgeous strawberries. But I also realized that while I have a Strawberry-Rhubarb Jam recipe on the site, I didn’t have a strawberry jam. So here it is.

Although I’m giving you a recipe for the amount of strawberries that I used, you can use the same proportions if you have just a basket…or a bushel. You’ll just need to do a slight amount of math. Only the cooking time will change, so keep an eye on things.

Jam-making is not something you walk away from and you need to rely more on look and feel, rather than exact times. Another thing about jam-making is that fruit and berry jams are always better made in small batches; the shorter the cooking time, the better the flavor. So if you have more than 2-pounds (900g) of strawberries, consider making jam in a couple of batches rather than one big one.

Strawberry Jam

2 pounds (900g) strawberries
1 1/4 pounds (2 2/3 cups, 580g) sugar
one lemon, organic or unsprayed
optional: kirsch (or eau-de-vie, or crème de cassis)

Wash and hull the strawberries and cut them into quarters. If some are larger or smaller, just make sure the pieces all about the same size.
2. Toss them in a large pot, such as a Dutch oven casserole made of a nonreactive material, with the sugar. Cut the lemon in half, squeeze the juice into the pot, and add the lemon halves to the berries. Stir well, cover, and let sit a couple of hours (up to 8 hours) at room temperature, stirring one or two times while they marinate.
Put a small plate in the freezer. Turn the heat on under the strawberries to medium-high and cook the strawberries, stirring occasionally, as they reduce and the juices thicken. If a lot of foam rises to the surface, skim it away. When the syrup is the consistency of warm maple syrup – it will take about 10 to 15 minutes or so, depending on the pot and berries, turn off the heat and put a spoonful of the jam on the frozen plate and return the plate to the freezer. Check it in a few minutes; if it wrinkles when you nudge it, it’s done. If not, return the plate to the freezer and cook the jam a little more, testing it again. It may take a few times before you get it to the right consistency.
When the strawberry jam is done, remove the lemon and stir in a few drops of kirsch, if using, then ladle the jam into the prepared jars.
