The idea came from wanting to do something different with the same dough I use every weekend. A calzone felt right. The same flour, the same starter, the same long fermentation, but folded around something that surprises you when you cut it open.

Fig jam and dates together have a particular kind of sweetness. It's not sharp or cloying. It's deep and a little earthy, the kind of thing that makes sense alongside the tang of sourdough in a way that refined sugar wouldn't. The sesame crust adds a toasted, nutty finish that pulls the whole thing together.

Formula#

Ingredient	Weight	Baker's %
Bread flour	500g	100%
Water	350g	70%
Starter (active)	100g	20%
Fine sea salt	10g	2%
Fig jam	3 tbsp	-
Medjool dates, roughly chopped	80g	-
Sesame seeds (for coating)	~30g	-

The hydration here is lower than my standard sourdough. I bring it down to 70% instead of the usual 76 to 78%, because you need a dough that holds its shape when folded and sealed rather than one that wants to spread.

Notes on the Filling#

Fig jam. Use a good one with visible fruit texture rather than a smooth, jellied version. You want small pieces of fig throughout the filling, not a uniform paste. The jam also acts as a binder, helping the dates stay in place when you fold the dough over.

Dates. Medjool dates are worth it here. They're softer and more caramel-like than other varieties, and they hold their shape when baked rather than drying out. Remove the pits, tear or chop them roughly into thirds, and don't be too neat about it. Irregular pieces create better texture variation in the finished calzone.

Getting the ratio right. Three tablespoons of jam to 80g of dates gives you a filling that's generous but not overpacked. Too much filling and the seam tears in the oven. You want just enough that every bite has filling without the dough struggling to hold it.

Mix and Bulk Fermentation#

Mix and bulk ferment as you would a standard sourdough. At 70% hydration the dough will feel stiffer than usual, and that's fine. Three sets of stretch and folds over the first 90 minutes, then leave it alone.

Total bulk is around 4 hours at 76°F. You're looking for about 50% volume increase and a dough that holds its shape when you pull a piece away.

Shaping#

Turn the dough onto a lightly floured surface and flatten into a circle, roughly 10 to 12 inches across. Spread the fig jam over one half of the circle, leaving a 1-inch border at the edge. Scatter the date pieces over the jam. Fold the empty half of the dough over the filling, aligning the edges, then press and crimp the seam firmly. Use your fingers to press down along the edge, then fold it over itself.

Brush the top generously with water and press the surface into a plate of sesame seeds to coat. The seeds need to adhere before baking, so press firmly enough that they embed slightly into the surface.

Baking#

Place on a parchment-lined baking sheet. No Dutch oven here. You need the open oven heat to get the crust properly crisp on all sides.

Bake at 500°F for 18 to 22 minutes. The calzone is done when the crust is deeply golden and the sesame seeds are toasted, not pale. The base should be firm when you tap it.

Rest for at least 20 minutes before cutting. The jam filling holds heat for a long time, and cutting too early collapses the interior.

How to Eat It#

In thick slices, warm or at room temperature. It's good on its own. It also works alongside a soft cheese like ricotta, labneh, or fresh chèvre, which provides a cool, milky contrast to the sweet filling and toasted sesame crust.

It keeps well for two days, tightly wrapped. The crust softens but the interior improves slightly as the fig and date flavours meld together overnight.
