Ingredients

• 350ml Martini Rosso
• 150ml gin
• 4 tsp icing sugar
• 24 frozen raspberries
• 2 bottles chilled Prosecco or other sparkling wine

Mix the Martini and gin together and chill or store in a bottle if making ahead.

If you have room in your fridge or freezer, chill your Champagne glasses, too.

When your guests are due to arrive, spoon ½ tsp icing sugar into 8 Champagne glasses. Pour over the Martini mixture, mix with a spoon and add the frozen raspberries. Top up with the sparkling wine just before serving.
