Chef Tips
Keep the heat low when melting the chocolate
Chocolate is sensitive to heat. If the bowl touches the simmering water, or the water boils hard, the temperature can spike and the chocolate will seize into a grainy, unworkable mass. Keep the water at a gentle simmer, not a boil, and make sure the base of the bowl sits above the waterline. Stir regularly and remove from the heat as soon as it’s smooth. You can also melt in the microwave in 30-second bursts at 50% power, stirring between each round.
Layer the mix-ins rather than stirring everything together
Pouring half the chocolate in first, then scattering the mix-ins, then covering with the rest gets everything suspended evenly through the slab. If you stir all the mix-ins into the chocolate before pouring, they sink to the bottom as it sets and you end up with a thick chocolate top and a crowded base. The layering method takes an extra 30 seconds and makes a significant difference to how the finished pieces look and eat.
Storage
Keep in an airtight container in the fridge for up to 2 weeks. Rocky road can be kept at room temperature but the chocolate softens quickly, especially in summer. Always slice it cold straight from the fridge for the cleanest cuts. Use a sharp knife and press firmly straight down rather than dragging through. You can also put it in the freezer to keep it longer.
FAQs
Can I swap out the mix-ins? Yes, the mix-ins are completely flexible. Glace cherries, pistachios, dried cranberries, honeycomb, or different M&M colours all work well. Keep the total weight of add-ins roughly the same so the chocolate-to-mix-in ratio stays balanced. The only rule is that anything you add should be dry. Wet or juicy mix-ins can cause the chocolate to seize.
Can I use dark chocolate instead of milk? Yes, though the result will be noticeably more bitter and the slab will set harder. Dark chocolate also slices differently, with a sharper snap. I prefer milk chocolate for this recipe because it balances the sweetness of the marshmallows and lollies, but a 50/50 mix of dark and milk is a good middle ground if you want something less sweet.
Is this recipe gluten free? Yes, as written. None of the core ingredients contain gluten. Just check the labels on your chocolate and M&Ms if you need to be strict about it, as some brands use shared manufacturing facilities. Turkish delight is naturally gluten free but worth confirming on the packet.
