These homemade sugar plums taste best if you toast the nuts ahead of time. To do so, spread the nuts on a sheet pan and bake at 350˚F for 6-7 minutes, until they smell fragrant and nutty. If you want to skip the toasting step, that's fine.
Chop all of the dried fruit finely. Add the fruit and nuts to a food processor and pulse until finely chopped. Add all remaining ingredients (except sugar) and pulse again until the mixture is sticky and comes together.
Use a 1 tbsp cookie scoop to portion out the plums, then shape into an oval. Optional: use a toothpick to make an indentation on the front. Roll in sugar until well coated and (optional) stick a little rosemary sprig in the top as a stem. Enjoy!
