Grandmother Antonietta’s Mixed-Fruit Jam — Quattro Stagioni
Italian mixed-fruit jam from a Quattro Stagioni promotional collaboration, retained with an explicit refrigerator/freezer safety adaptation.
Ingredients
Mixed-Fruit Jam
- 1 kg mixed fruit cleaned and prepared
- 700 g granulated sugar
- 1 lemon juice
Equipment
- 3 Quattro Stagioni-style jars clean, heat-safe jars
- Canning funnel optional
- Cold saucer optional gel test
Directions
Documented Preparation
- Clean and prepare the mixed fruit, removing pits, cores, or damaged portions as appropriate.
- Combine the prepared fruit, granulated sugar, and lemon juice in a nonreactive saucepan.
- Cook while stirring until the fruit breaks down and the mixture reaches a jam consistency. Use a cold-plate gel test if desired.
- Transfer the hot jam to clean heat-safe jars, leaving room for expansion if freezing.
- Because the available source does not provide a validated jar size, headspace, heat-process, or altitude schedule, cool promptly and refrigerate or freeze. Do not store at room temperature.
Keep this card open while you work. Ingredients and directions stay together on larger screens and stack clearly on phones.
Recipe Notes
Safety status: incomplete/untested for shelf-stable home canning. The source supplies ingredients and yield but no validated jar size, headspace, processing temperature or time, altitude adjustment, or mixed-fruit specification. Refrigerate or freeze. For shelf-stable storage, choose a tested jam formula for the exact fruit combination and follow its complete boiling-water process.
