Wash tomatoes, quince, bell and hot peppers in warm water. Cut out the core with seeds from quinces and peppers. Cut the quince into large cubes, bell and hot peppers into large slices. Wash the dill, horseradish and currant leaves, dry on a paper towel, then chop coarsely. Peel the garlic. Sterilize a canning jar with a lid.
Fill the jar. Place in a jar layers of tomatoes, pieces of quince, bell and hot peppers, dill, horseradish and currant leaves, garlic, black peppercorns.
Make the marinade. Pour 1.5 cups of water into a saucepan and place on the stove. When the water boils, pour it into the jar to the very top and cover with a lid. Leave for 15 minutes, then pour this water into an empty saucepan and let it boil.
Preserve quince with tomatoes. Add salt and sugar to the jar. 30 seconds after the water boils, pour it back into the jar. Add vinegar to the jar and seal it with a sterile lid and a preservation key.
For a beautiful serving, you can use small jars, pouring the brine into it along with the appetizer, so that it is convenient to serve it in portions, preserving the taste of the preparation.
