If you are going to bake a Christmas Stollen, it would be good to prepare these rum-preserved dried fruits beforehand. You can also try a smaller batch as the amount is easy to adjust.
This is the first time in over 10 years since I made this for Stollen and fruit cake.
The amount to make is up to you and you can make small amount. Be sure to prevent the fruits from sticking out from the rum.
Enjoy Japanese food around the world.
