Unlike truffle oils, which are composed of chemicals combined to simulate the flavour of truffles, truffle salts contain the real deal. I've seen black truffle salts, but have had a hard time finding them flavoured with white truffle. The Tartufi Morra sale al tartufo bianco, available at Pavilion Gourmet (45 Hau Wo Street, Kennedy Town, tel: 2698 1090), contains grey sel de Guerande and 2 per cent white truffle ( Tuber magnatum pico). It costs HK$164 for 100 grams.
I ate a delicious salad on a recent trip to France and, when I asked about the dressing, the waiter said it was made with hazelnut oil. So I was excited to find Beaufor huile de noisette, made in Reims, France, at City'super (Times Square, Causeway Bay, tel: 2506 2888). The 500ml container (HK$133) is quite large, so it's best to store it in the fridge; the oil will thicken in the cold but becomes liquid again at room temperature.
I love the Kin No Mame rice crackers sold at Fresh Mart at Sogo (555 Hennessy Road, Causeway Bay, tel: 2833 8338); the vendors are happy to give out samples of their wares, which are far more delicate than many other types of rice cracker. There's a large variety of flavours, too, including salty, sweet, green tea, nut and - my favourite - chilli. They cost HK$110 for 250 grams.
