Lychee martini

Step 1

To make the sansho vodka, combine the sansho peppercorns and vodka. Leave to infuse overnight, then filter out the peppercorns using a fine muslin cloth.

Step 2

For the lychee syrup, weigh the lychees and add the same volume of water. Tip into a high-powered blender and whizz until smooth, then pour through a fine sieve set over a bowl. Weigh the lychee liquid and add the same weight of caster sugar, then stir to dissolve.

Step 3

To make the cocktail, measure out all of the ingredients for the cocktail into a shaker. Fill with ice and shake vigorously for 20-30 seconds. Strain into a chilled martini glass and garnish with a strip of lime peel, gently twisting over the drink to release the oils.
