Wash the strawberries and pat them completely dry.
Melt the white chocolate in a heatproof bowl over simmering water or in short bursts in the microwave.
Stir in the vegetable oil if using.
Hold each strawberry by the stem and dip into the melted white chocolate, leaving a ghost-like shape at the bottom.
Place onto baking parchment and allow excess chocolate to drip down naturally.
Before the chocolate sets, add two chocolate chips for eyes, or pipe eyes with black icing.
Chill in the fridge for 10-15 minutes until set.
