The rosehips do must be wrinkled and wilted from the first frost. Cut out stems and flowers, put fruit in balloon, bring sugar with vanilla sticks and tap water to a boil until sugar is dissolved. Add juice of one lemon or Citropect, skim. Pour lukewarm over the rose hips. Cover with a muslin cloth and keep warm. Ferment for about 3-4 weeks, drain through a muslin cloth. Store in a cool place and let sit for a couple of weeks.
Tip: Always use organic lemons for cooking, if possible!
