Preserve fruit juice without preserving
If you want to preserve fresh fruit juice or tomato juice, etc., without cooking, then this is done as follows:
Fill the appropriate juice in bottles with a slender neck, to about 2-3 cm below the opening. Then fill in the space with a good olive oil and close everything either with plastic wrap or with the closure of the bottle. It should be ensured that now no longer the bottle may be tilted. For later use, simply put some kitchen paper in the neck of the bottle and let it absorb.
