If you can’t find any green glacé cherries then you could substitute it for Angelica. Angelica is in the parsley family, and is often candied to be used as cake decoration. In fact, it was the original green candy in fruit cake recipes. Angelica can also be a bit of a nightmare to track down though! If you can’t find any then you can just use red glacé cherries alone. Your mini chocolate Christmas puddings won’t look quite the same, but they’ll still taste delicious.
