Chef's tips: Chop chocolate finely so it melts completely. Don't skip the strainer — it catches any bits of cooked egg for silky texture. Patience with chilling is non-negotiable; a warm base in the churn leads to ice crystals. If the gelato is too hard straight from the freezer, let it sit on the counter for 10 minutes before scooping. Storage: Press plastic wrap directly onto the surface before sealing the lid to prevent ice crystals. The gelato keeps for up to 2 weeks, best within 5 days. Variations: For dairy-free, substitute full-fat oat milk or coconut milk for whole milk. For spicy gelato, add 1/4 tsp cayenne to the milk as it heats. For kid-friendly, swap 3 oz dark chocolate for milk chocolate. For mint chocolate, steep fresh mint leaves in the milk then strain and add a drop of peppermint extract.
