Combine the blackcurrant leaf gin, morello cherry and lemon and chervil water in a mixing glass. Stir over ice until well chilled and diluted. Strain into a Nick and Nora glass. Top carefully with lemon foam using a siphon to build a clean, flush top on the drink.

Blackcurrant Leaf Gin

Combine 250ml gin with 5 large blackcurrant leaves in a heatproof container, making sure to tear the leaves slightly first. Bain marie for 1 hour at a gentle simmer, or seal in a zip-lock bag and submerge in hot water from the tap, topping it up every 15 minutes to maintain the temperature. Strain and cool before using.

Lemon and Chervil Water

Place 2 strips of lemon peel and 5 chervil sprigs in 500ml of water. Bain marie for 30 minutes. Again, if you don't have a bain marie just follow the step above. Strain and cool. Can be made ahead and refrigerated for up to 3 days.

Lemon Foam

Combine 150ml fresh lemon juice, 150ml sugar syrup and 1g xanthan gum. Blend briefly to incorporate the xanthan. Pour into a siphon and charge with 2 N2O canisters. Allow to rest in the fridge for 20 minutes. Shake well before each use.
