Homemade Ketchup with Apples

Wash the vegetables thoroughly. Quarter the tomatoes. Also quarter the apples, remove the core, and cut them into smaller pieces. Peel and quarter the onions.

Place the prepared vegetables in a large pot. Add cloves, allspice, peppercorns, and bay leaves. Simmer over medium heat for about 45 minutes, stirring occasionally.

Purée the mixture with an immersion blender and then strain it through a fine sieve to remove seeds and skins. Return the mixture to the pot.
