Cooked grape must
Mosto cotto is grape must concentrated by cooking into a sweet, dark condiment. In chestnut calzoncelli it joins the filling, bringing grape sweetness alongside chocolate and spice.
- Base
- Grape must.
- Preparation
- Concentrated by cooking.
- For this filling
- A finished sweet grape condiment, measured separately from the pastry wine.
Measure the finished condiment
Use prepared cooked grape must rather than reducing the recipe’s white wine. Stir the measured amount into the mashed chestnuts with the chocolate and aromatics. Mix thoroughly so sweetness is distributed throughout the filling, then let it cool before shaping the pastries.
Grapes in the sweet pantry
Cooking grape must reduces its water and concentrates its flavor. The resulting condiment appears in the sweet cooking of several Italian regions. In Lucanian chestnut calzoncelli, it is one of the filling ingredients, while white wine belongs to the pastry dough. Names such as mosto cotto and vincotto can appear on different products. Read the actual ingredients: grape must, fig syrup, fermented cooked wine and vinegar-based condiments do not identify the same preparation. The grape base is the useful distinction when shopping for this filling.
A little with cheese or dessert
Outside the filling, use small spoonfuls as a sweet condiment with cheese or a simple dessert. Add gradually and taste: concentration varies between products. Its fluid syrup texture is useful when you want sweetness to spread over a surface rather than stay in a solid piece.
Check the grape ingredient
Choose a product identified as cooked grape must and suitable for sweet cooking. Read the ingredients and any storage instructions before buying. The word vincotto alone is not enough to distinguish a grape preparation from one based on figs or from a flavored balsamic condiment.
Close the bottle after measuring
Follow the maker’s directions for the unopened bottle and after opening. Refrigerate when directed, close the cap and use clean utensils. Do not infer a home-preserving schedule or an opened shelf life from the syrup’s sweetness.
