Halloween needs at least one treat that looks slightly dangerous. These are classic toffee apples with an optional jet-black “poison” shell: crunchy, glossy, and perfect for parties or a trick-or-treat table. Best eaten the same day, while the shell is perfectly brittle.

One bite won’t send you to sleep. Probably.

Makes: 8 apples
Hands-on time: about 30 minutes
Setting time: 15–30 minutes

Ingredients

  • 8 small–medium apples (Granny Smith for tart contrast, or red apples)
  • 400 g caster (superfine) sugar
  • 100 ml water
  • 4 tbsp golden syrup (or light corn syrup / liquid glucose)
  • 1 tsp lemon juice or white vinegar
  • Black gel food colouring (or red), optional for the Halloween look
  • Optional: edible glitter, crushed nuts, pretzels, or Halloween sprinkles
  • 8 sturdy lolly sticks, thick skewers, or clean twigs

Equipment

  • Heavy-based saucepan
  • Candy thermometer (ideal)
  • Baking parchment or a silicone mat
  • Pastry brush

Method

  1. Prep the apples. Wash thoroughly. Dunk in boiling water for a few seconds to remove the wax coating (this helps the toffee stick), then dry completely. Remove the stems and firmly insert the sticks into the stem end. Line a tray with parchment.
  2. Make the toffee. In a clean, grease-free heavy saucepan, combine the sugar, water, and lemon juice or vinegar. Heat gently, stirring only until the sugar dissolves, then stop stirring. Add the golden syrup. Bring to the boil and cook without stirring until it reaches hard-crack stage: 150 °C / 302 °F on a thermometer. No thermometer? Drop a little into cold water: it should set instantly into a hard, brittle piece. Off the heat, swirl in the food colouring (black for dramatic poison apples) and let the bubbles subside for a smoother finish. Brush down any sugar crystals on the sides of the pan with a wet pastry brush as needed.
  3. Dip. Working quickly, tilt the pan and dip each apple, turning to coat evenly. Let the excess drip off, then stand it on the parchment, stick upright. If the toffee thickens, reheat it briefly and gently. If you like, roll the still-warm coating in nuts, pretzels, or sprinkles.
  4. Set. Leave at room temperature until fully hard, 15–30 minutes. Do not refrigerate.

Tips for success

  • Keep the pan and tools completely grease-free to avoid crystallisation.
  • Work fast once the toffee is ready. It sets quickly.
  • For extra Halloween flair, use natural twigs, add black glitter, or stick on candy eyes while the coating is still tacky (or gently reheat a spot with a kitchen torch).
  • Store wrapped in parchment or cellophane at room temperature for up to a day. The coating softens over time.
  • Clean-up: soak the pan in hot water and the hardened toffee dissolves.

Safety note

Hot sugar is extremely dangerous. Keep children and pets away, and never touch the toffee until it is fully set.
