Andrzejki, or St. Andrew's Day, is a very popular tradition in Poland
'In (...) Poland (...) superstitious belief exists that the night before St. Andrew's Day is specially suitable for magic that reveals a young woman's future husband or that binds a future husband to her. Many related customs exist: for example (...) the pouring hot wax from a candle through a key hole into cold water, divining the future husband's profession from the shape of the resulting piece'.

This is a little off the food topic, but it's a fun after-dinner activity. We celebrated the Polish Feast of St. Andrew – Andrzejki. Always celebrated on Nov. 29 or the 30, depending on what region in Poland you are from, as it is either celebrated on the day or the eve. You melt wax and pour it through a hollow key handle into a bowl of cold water where it solidifies. You look at its shadow against the wall and interpret it. It is a prediction for the upcoming year.
