          Method: 
          Whisk the egg whites in a clean, 
          grease-free, heatproof bowl until frothy, then gradually whisk in the 
          icing sugar followed by the vanilla essence. Set the bowl over a pan 
          of gently simmering water and whisk until the meringue holds its shape 
          and leaves a thick trail when the whisk is lifted out. Line a baking 
          (cookie) sheet with baking parchment and draw six 7.5 cm/3 in circles 
          on the paper. Using half the meringue mixture, spoon a layer of 
          meringue inside each circle. Place the remainder in a piping bag and 
          pipe two layers of meringue round the edge of each base. Dry in a 
          preheated oven at 150°C/300°F/gas mark 2 for about 45 minutes. |
