Combine chopped apples, both sugars, cinnamon, nutmeg, salt, lemon juice, caramel sauce, and vanilla in a heavy-bottomed pot. Stir to blend.

ook over medium-high heat, stirring occasionally, until juices bubble and apples begin to soften—about 10–15 minutes.

Reduce heat to medium or medium-low; continue cooking until apples are tender and the mixture thickens—about 15–20 more minutes. Stir frequently to prevent scorching.

If desired, mash lightly for a chunkier or smoother texture. Continue simmering until jam reaches preferred consistency (test on a chilled plate).

Remove from heat and let cool slightly. Spoon into sterilized jars and refrigerate. Jam will thicken as it cools.
