Reserve 8 strawberries for decoration. Blend the remainder in a food processor or blender, or use a hand-held blender to give a smooth puree. Strain the strawberry liquid through a fine sieve to remove the pips. Add the sweetener, if using, then chill until icy cold.

When ready to serve, share the chilled strawberry mixture between 8 Champagne flutes. Partially slice through the reserved strawberries, so that they sit on the rim of each glass, then top up with chilled Champagne or Cava.

Serve immediately. Cheers!
