Chiaverini Apricot Jam. The two young Chiaverini brothers founded F.lli Chiaverini & C. in 1928 in Florence. It was a small operation situated just outside the ancient walls of the city. The brothers carefully selected their ingredients from the local farmers’ produce and followed time-honoured family recipes to create marmalades, jams and preserves. Perfect to be spread on dried toast in the morning.
