I just finished making a small batch of Christine Ferber's raspberry with chocolate jam. It was incredibly messy after walking away from the stove for 2 minutes resulting in my biggest kitchen mess ever. Thank goodness this wasn't my own kitchen. Considering the very small yield, itt was also incredibly expensive to get organic raspberries and top notch bittersweet chocolate. In the end, it was so worth it, and I am a jam snob for life.
