Just done this Tara, using a Rumtoph jar, speciial for the purpose, made in Germany, a layer of fruit, then sugar, then rum or any spirits and keep repeating. Leave for several months.Keep it weighted down with a saucer, or if a saucer won 't fit, use a large mug as I've done . Have been picking cherries for the last week, run out of ideas on how to use 'em. Do you think sweet jars filled with syrup would serve the same purpose as rum jars.
