I bought ganache chocolates by Alain Ducasse on a recent trip. They are made of single-origin cocoa and are incredibly dark and rich. Like smoking or drinking, tasting this kind of chocolate for the first time can be repulsive, but then it becomes like a delicious, addictive drug.

I love Godiva’s Truffle Speculoos chocolates. They’re inspired by the traditional Belgian biscuit speculoos and are utterly irresistible, with a light mousse centre. I buy them loose in bags from Godiva’s in-store shop at Harrods. harrods.com.

I adore the I Am Joy chocolates from Café Gratitude in Los Angeles. They’re delicious and deceptively healthy, made of shredded coconut, almonds and a hard chocolate shell, with no added sugar. $3 each; 639 North Larchmont Boulevard, Los Angeles, CA 90004 (+1323-580 6383; cafegratitude.com).

I recommend a visit to the chocolatier Jacques Genin, who is based in Le Marais in Paris. He uses unusual ingredients such as jasmine – his work actually inspired my Noir Aphrodisiaque fragrance. jacquesgenin.fr.

I’ve given up lots of things to be healthy, including coffee, but there’s no way I could give up dark chocolate – even my nutritionist is relaxed about it. My favourite is Pierre Marcolini’s; I can’t get it in the States, so I stock up when I’m in Europe. eu.marcolini.com.

My absolute favourites are Booja Booja Almond Salted Caramel Chocolate Truffles, which are dairy-free, gluten-free, soya-free and the best truffles I’ve tasted. £3.99 for 69g; ocado.com.
Alberto Morillas, perfumer
For me, it’s Amandes Princesse chocolate almonds from the Geneva confiseur Auer. Opening the packet is dangerous because each almond tastes better than the previous one. About £25 for 250g; Rue de Rive, 1204 Geneva (+4122-311 4286; chocolat-auer.ch).

Chocolate is the one indulgence I couldn’t forego. In San Francisco I go to Poco Dolce for their thick slabs of dark chocolate; in London I go to Rococo for the really fantastic sea-salt wafers. Poco Dolce, 2419 3rd Street, San Francisco, CA 94107 (+1415-255 1443; pocodolce.com). Rococo Chocolate, 321 King’s Road, London SW3 (020-7352 5857; rococochocolates.com).

I love very dark chocolate, and Villars from Switzerland is my favourite; it’s made without added sugar, so I like to snack on it throughout the day. Villars, about £2.50 for 100g; villars.com.
