Step-by-Step Guide to Making Mary Berry Rocky Road

• Melt the chocolate mixture – In a heatproof bowl over simmering water, melt the chocolate, butter, and golden syrup until smooth.

What I Got Wrong (And How I Fixed It)

• Used too much butter – It made the mixture greasy; reducing butter fixed the texture.
• Over-crushed the biscuits – The bars became dense; leaving larger chunks improved the crunch.
• Added marshmallows too early – Hot chocolate melted them; cooling the mixture solved it.
• Skipped lining the tin – Removing the rocky road was difficult; parchment paper fixed this.

FAQs

How do I keep my Rocky Road from falling apart?

To keep Rocky Road firm and easy to slice, make sure the melted chocolate mixture is fully mixed with the biscuits and marshmallows so everything binds together. Press the mixture firmly into the tin and chill it for at least 2–3 hours. Using enough chocolate and not over-crushing the biscuits also helps the bars hold their shape.

Why did my marshmallows melt in the Rocky Road mixture?

Marshmallows melt when the chocolate mixture is too hot. Let the melted chocolate, butter, and syrup mixture cool for 8–10 minutes before stirring in the marshmallows. This helps them stay whole and gives the Rocky Road its classic chewy texture.

How can I cut Rocky Road without it crumbling?

For neat slices, remove the chilled Rocky Road from the fridge and let it soften for 5–7 minutes. Then use a sharp knife warmed under hot water and wiped dry. The warm blade glides through the chocolate and biscuit pieces without cracking or crumbling.

Can I make Rocky Road ahead of time for parties?

Yes, Rocky Road is perfect for making in advance. Prepare the mixture the day before, chill it overnight, and store it in an airtight container. This helps the flavours develop and makes slicing easier before serving.
