Besides excellent beef, Hawksmoor in London have very good and sophisticated cocktails , and a very pleasant cocktail bar in Seven Dials (here is a link to their catalogue). They have published a book (Hawksmoor at Home) that is an excellent and entertaining read, celebrating Britishness in food (if you have the book take a look page 117).
There a section on anti-fogmatics ( anti-fogmatic: An alcoholic drink taken in the morning to brace oneself before going out into bad weather, before 11am, or whenever steam and energy are needed). We take ours on a latter hour, and here is our favorite:
1 tsp orange marmalade
50ml good gin
15ml lemon juice
a dash of orange bitters
a twist of orange peel
Place a headed barspoon (or teaspoon) of marmalade in a shaker. Add the gin and stir, pressing the marmalade against the side of the shaker to loosen it up. Add the other ingredients, fill up the shaker with ice cubes and shake hard to break down and dissolve the marmalade. If you’re left with a big glob of marmalade after shaking you either haven’t shaken hard enough or your marmalade is particularly resilient – in which case dissolve it in a small amount of boiling water and shake it all up again (but do it quickly so the drink doesn’t become too diluted). Strain into a Martini glass and serve with a twist of orange peel.
For the twist of orange peel: To make the orange twist, use a potato peeler to pare off a rough rectangle of rind from the top of the bottom of an orange. Using your fingers bend the rind over the drink -outer side of the orange over the drink – until the oils in the skin spray over the drink. Then twist the rind into a spiral and drop into the drink.
