Does the gin I use actually matter here?

Yes, but maybe less than you think. A classic London Dry gives the juniper a clean platform to meet the Fernet's menthol, and that contrast is the whole pleasure. A softer, more floral modern gin can get bulldozed. If you only own one bottle and it is a workhorse London Dry, you are fine. Spend your worry on the vermouth instead.

Can I scale up the Fernet if I love the stuff?

You can do anything you want in your own kitchen, but understand the cost. Push past two dashes and the Fernet stops being a haunting back note and starts being the entire conversation, at which point you have essentially made a bitter sipper and buried the gin and vermouth for nothing. If you genuinely want a Fernet-forward drink, just drink Fernet. The Hanky Panky is about restraint doing more than excess.

Why orange peel and not lemon, like a Martini?

Because the drink is sweeter and darker than a dry Martini, and lemon's sharp brightness would fight it. Orange oil is rounder and warmer, and it shakes hands with both the sweet vermouth and the Fernet's herbal bitterness instead of slicing across them. Try it with lemon once if you are stubborn. You will go back to orange.

The Hanky Panky: Fernet's Trojan Horse in a Coupe

Two dashes of anything sounds like a rounding error. In the Hanky Panky it is the whole point. Fernet-Branca, that bitter Italian medicine that bartenders drink to punish themselves, goes into a soft gin-and-vermouth bed and turns it into something that argues back. This is the drink for the night you want a Martini that has lived a little.

1.5 ozSweet Vermouth

Garnish: Orange peel

Stirred, always. You are building a clear, spirit-heavy drink, and shaking would bruise it into cloudy nonsense for no reward. The ratio is the trick: equal parts gin and sweet vermouth, a true 50/50, which means your vermouth has to be alive. Old, oxidized vermouth that has been sweating in a warm well for three months will make this taste like cough syrup. Buy a fresh bottle, keep it in the fridge, and treat it like the wine it is. The Fernet goes in by the dash, and you respect that. Two dashes, no more, because Fernet is a bully and given an inch it eats the whole glass. Stir over good ice until properly cold and slightly diluted, then strain into a chilled coupe. Express an orange peel over the top and drop it in. The citrus oil bridges the gin's botanicals and the Fernet's menthol bitterness, and it matters more than its size suggests.

The Hanky Panky is a Martini at its bones, and the bones are what matter. The Martini family is built on a base spirit braced by an aromatized wine, and here that is gin leaning on sweet vermouth in equal measure. Strip the Fernet out and you have a sweeter, redder cousin of the dry Martini, the same skeleton as a Bijou or a Bobby Burns, drinks where vermouth is a structural partner rather than a rumor. That is the family logic: spirit plus fortified wine, stirred cold, no citrus to muddy the architecture. You can see the same DNA running through the Bamboo and the Adonis, which lean on sherry, through the Boulevardier, which swaps in whiskey and Campari, through the Algonquin and the Bensonhurst. The Fernet here is a modifier, the way orange bitters modify a classic Martini. It does not change what family the drink belongs to. It just gives the Martini a darker mood and a longer finish.

Ada Coleman ran the American Bar at the Savoy in London at the turn of the last century, back when a woman running one of the most famous bars in the world was close to unthinkable. She was good enough that nobody could argue. The story goes that the actor Charles Hawtrey, a regular, asked her for something with real punch, something to wake him up after a long day. She kept tinkering and handed him this. He knocked it back and said it was the real hanky-panky, and the name stuck. Whether the quote is exact or polished by a century of retelling, the drink is real and it is hers, which is more than most cocktails can claim about their origins. What makes it endure is the nerve of it. Fernet-Branca was, and is, a digestivo, the bitter brown stuff Italians and now every bartender in your city drink after service to settle the stomach and signal tribe membership. Coleman saw it as an ingredient before that was a fashionable idea. Two dashes is a restrained, confident move from someone who knew exactly what that amaro would do to a gentle drink. Most modern versions overpour the Fernet because the bartender wants you to taste their cleverness. Resist. The Hanky Panky works because the bitterness arrives late, on the back end, after the gin and vermouth have already lulled you. It is a drink with a second act.
